windows - Python not working in the command line of git bash

Question

Python will not run in git bash (Windows). When I type python in the command line, it takes me to a blank line without saying that it has entered python 2.7.10 like its does in Powershell. It doesn't give me an error message, but python just doesn't run.

I have already made sure the environmental variables in PATH included c:\python27. What else can I check?

---

A session wherein this issue occurs looks like the following:

user@hostname MINGW64 ~
$ type python
python is /c/Python27/python

user@hostname MINGW64 ~
$ python

...sitting there without returning to the prompt.

Answer 1

Temporary solution

Just enter this in your git shell on windows - > alias python='winpty python.exe', that is all and you are going to have alias to the python executable. This alias will be valid for the duration of the shell session.

winpty is a Windows software package providing an interface similar to a Unix pty-master for communicating with Windows console programs.

Permanent solution

Add the command to your .bashrc in the users home directory.

Using CLI

This can be accomplished from git bash like so:

echo "alias python='winpty python.exe'" >> ~/.bashrc

which will create .bashrc in the current users home directory if the file doesn't exist or append the alias to the end of .bashrc if it does.

Using a text editor

Alternatively, you could first create a .bashrc. Depending on your file manager, this may be easier to accomplish in git bash like so:

cd ~
touch .bashrc

At which point you can open .bashrc in your prefered text editor and add it there.

To apply the change, either use the command source .bashrc or restart the shell.

Answer 2

I don't see next option in a list of answers, but I can get interactive prompt with "-i" key:

$ python -i
Python 3.5.2 (v3.5.2:4def2a2901a5, Jun 25 2016, 22:18:55)
Type "help", "copyright", "credits" or "license" for more information.

Answer 3

This is a known bug in MSys2, which provides the terminal used by Git Bash. You can work around it by running a Python build without ncurses support, or by using WinPTY, used as follows:

To run a Windows console program in mintty or Cygwin sshd, prepend console.exe to the command-line:

$ build/console.exe c:/Python27/python.exe
Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> 10 + 20
30
>>> exit()

The prebuilt binaries for msys are likely to work with Git Bash. (Do check whether there's a newer version if significant time has passed since this answer was posted!).

As of Git for Windows 2.7.1, also try using winpty c:Python27/python.exe; WinPTY may be included out-of-the-box.

Answer 4

I am windows 10 user and I have installed GIT in my system by just accepting the defaults.

After reading the above answers, I got 2 solutions for my own and these 2 solutions perfectly works on GIT bash and facilitates me to execute Python statements on GIT bash.

I am attaching 3 images of my GIT bash terminal. 1st with problem and the latter 2 as solutions.

PROBLEM - Cursor is just waiting after hitting python command

SOLUTION 1

Execute winpty <path-to-python-installation-dir>/python.exe on GIT bash terminal.

Note: Do not use C:\Users\Admin like path style in GIT bash, instead use /C/Users/Admin.

In my case, I executed winpty /C/Users/SJV/Anaconda2/python.exe command on GIT bash

Or if you do not know your username then execute winpty /C/Users/$USERNAME/Anaconda2/python.exe

SOLUTION 2

Just type python -i and that is it.

Thanks.

Answer 5

Try python -i instead of python, it's a cursor thing.

Answer 6

Git Bash Workaround- Launch Python 2 & Python 3 with aliases

HI. This is (for me) the best solution to run both Python (Python 2.7 and Python 3.x) directly from Git Bash on Win 10 => adding aliases into the aliases file that Git Bash uses for.

Git Bash aliases file is aliases.sh. It is located in:

C:\path where you installed Git\etc\profile.d\aliases.sh

1) Open (with a text editor like Atom or other) the aliases.sh

for ex: in my case the file is in C:\Software\Develop\Git\etc\profile.d\aliases.sh

2) Add your alias for Python

In my case the python.exe are installed in:

C:\Networking\Network Automation\Python 2.7\python.exe
C:\Networking\Network Automation\Python 3.7\python.exe

So you must create 2 aliases, one for Python 2 (I named python2) and the other for Python 3 (I named just python) Git Bash uses linux file structure so you need to change the "\" for "/" and if you have a path like my example Network Automation you put it with " "

"Network Automation", for ex.

winpty is the magic command that will call the executable.

So add these lines at the beginning of aliases.sh

alias python2='winpty C/Networking/"Network Automation"/"Python 2.7"/python.exe'
alias python='winpty C/Networking/"Network Automation"/"Python 3.7"/python.exe'

3) Add or Modify other aliases (if you want)

I modified also the ll alias to show all the files and in a human readable list:

alias ll='ls -lah'

---

4) Save the aliases.sh file

---

5) OK!!! close and relaunch your Git Bash

Now, permanently you could launch both Python directly from Git shell just writting

$ python -> launch Python 3

$ python2 -> launch Python 2

$ ll -> enters a ls -lah to quickly show your detailed file list

Cheers, Harry

Answer 7

In addition to the answer of @Charles-Duffy, you can use winpty directly without installing/downloading anything extra. Just run winpty c:/Python27/python.exe. The utility winpty.exe can be found at Git\usr\bin. I'm using Git for Windows v2.7.1

The prebuilt binaries from @Charles-Duffy is version 0.1.1(according to the file name), while the included one is 0.2.2

Answer 8

2 workarounds, rather than a solution: In my Git Bash, following command hangs and I don't get the prompt back:

% python

So I just use:

% winpty python

As some people have noted above, you can also use:

% python -i

2020-07-14: Git 2.27.0 has added optional experimental support for pseudo consoles, which allow running Python from the command line:

See attached session.

Answer 9

type: 'winpty python' and it will work

gitbash has some issues when running any command that starts with python. this goes for any python manage.py commands as well. Always start with 'winpty python manage.py' At least this is what works for me. Running Windows 10.

Answer 10

You can change target for Git Bash shortcut from:

"C:\Program Files\Git\git-bash.exe" --cd-to-home 

to

"C:\Program Files\Git\git-cmd.exe" --no-cd --command=usr/bin/bash.exe -l -i

This is the way ConEmu used to start git bash (version 16). Recent version starts it normally and it's how I got there...

Answer 11

In addition to @Vitaliy Terziev answer

try touch .bash_profile and then add alias into the file.

Answer 12

I am using MINGW64 via Visual Studio Code on Windows 10 and trying to install node-sass (which requires python2). I followed felixrieseberg/windows-build-tools #56 on Github which solved my issue.

This is a special case, but I'm posting in case someone has the same problem:

npm --add-python-to-path='true' --debug install --global windows-build-tools

This installs python and other required build tools to %USERPROFILE%\.windows-build-tools\python27.

Answer 13

For python version 3.7.3 in vscode with gitbash as the default terminal I was dealing with this for a while and then followed @Vitaliy Terziev advice of adding the alias to .bashrc but with the following specification:

alias python=’“/c/Users/my user name/AppData/Local/Programs/Python/Python37/python.exe”’

Notice the combination of single and double quotes because of “my user name” spaces.

For me, "winpty" couldn't resolve python path in vscode.

Answer 14

Type the command PY instead of Python. Invoking the Interpreter (python.org).

Answer 15

Another example of this issue is using the AWS Elastic Beanstalk command line interface (awsebcli, eb cli) from the git bash (MINGW64, Mintty) in windows (using git version 2.19.0.windows.1).

I'm just posting this because it took me a while to end up here, searching for eb-cli specific issues.

Commands such as eb init or eb config save, which require user input, appear to cause a freeze/hang. In reality I guess the console is not updated with the text requesting user input. Moreover, eb deploy only updates the console text after the command has finished, so I don't get to see progress updates until finished.

As mentioned in the git for windows release notes (for v2.19.0) and e.g. in Xun Yang's answer, a workaround is to run

winpty eb <command> (instead of just eb <command>)

A alternative, as suggested in this git for windows issue, could be to use the windows native console instead of mintty (option during git installation).

Answer 16

The one worked for me is as mentioned earlier in these great answers above is the alias as follows: (I'm using anaconda, so first find where is the python path, then add it into the alias on git bash). 1. on anaconda terminal I run: where python 2. on git bash I run: alias python='winpty "C:\ProgramData\Anaconda3\envs\your_env_name\python.exe"' 3. Done. Python is defined inside the git Bash using the alias.

Thanks to (Vitaliy Terziev & hygull) for their very helpful answers.

1. python.exe -i works but got issues in exiting from the interactive mode by sending "^Z" (CTRL+Z). So, seem better to use winpty python.exe in Git Bash for Windows.
   

2. Use ~/bin directory to make a wrap/reference file (like ~/bin/python) which will be accessible everywhere (you may use different version reference like ~/bin/python37).
   Code inside the file:

#!/usr/bin/env bash
# maybe declare env vars here like
# export PYTHONHOME=/c/Users/%USERNAME%/.python/Python36
# export PATH="${PATH}:/c/Users/%USERNAME%/.python/Python36"

# replace %USERNAME%,
# or use "~" instead of "/c/Users/%USERNAME%" if it works
winpty /c/Users/%USERNAME%/.python/Python36/python.exe ${@}

I just don't like these "magic" aliases which you're always forgetting where it's coming from, and sometimes leads to issues in some cases.

3. Use ~/bin/python file and -i parameter:

#!/usr/bin/env bash
if [ -z "${@}" ]; then
    # empty args, use interactive mode
    /c/Users/%USERNAME%/.python/Python36/python.exe -i
else
    /c/Users/%USERNAME%/.python/Python36/python.exe ${@}
fi

Answer 18

I know this is an old post, but I just came across this problem on Windows 10 running Python 3.8.5 and Git 2.28.0.windows.1

Somehow I had several different 2.7x versions of Python installed as well. I removed every version of Python (3x and 2x), downloaded the official installer here, installed 3.8.5 fresh (just used the defaults) which installed Python 3.8.5 at this location:

C:\Users\(my username)\AppData\Local\Programs\Python\Python38

Then to get the command python to work in my git bash shell, I had to manually add the path to Python38 to my path variable following the instructions listed here. This is important to note because on the python installer at the bottom of the first modal that comes up it asks if you want to add the python path to your PATH environment variable. I clicked the checkbox next to this but it didn't actually add the path, hence the need to manually add the path to my PATH environment variable.

Now using my gitbash shell I can browse to a directory with a python script in it and just type python theScriptName.py and it runs no problem.

I wanted to post this because this is all I had to do to get my gitbash shell to allow me to run python scripts. I think there might have been some updates so I didn't need to do any of the other solutions listed here. At any rate, this is another thing to try if you are having issues running python scripts in your gitbash shell on a Windows 10 machine.

Enjoy.

Answer 19

if you run a Windows PowerShell command and an error occurs, the error record will be appended to the “automatic variable” named $error.

You can use the $error variable to find the errors, in the same PowerShell session.

The $Error variable holds a collection of information, and that’s why using $Error[0] can get to your error message objects. Also the $Error[0] variable will hold the last error message encountered until the PowerShell session ends.

Answer 20

Have a look at this answer:

Git Bash won't run my python files?

the path in Git Bash should be set like this:

PATH=$PATH:/c/Python27/
