Python ImportError: No module named wx

Question

Im sorry to ask this question again. I have searched and found endles repeats of it both on stackoverflow and also on general google search. Unfortunatly I just cant get my system sorted.

I have the following:

C:\Python27\Lib\site-packages\wx-2.8-msw-unicode

this folder contains the wx folder and also wx & wxPython folders which each contain the _init_.py files

When I import wx I get the error message "no module named wx"

What do I need to do in order to get Python to find the relevant files to allow me to "import wx" succesfully

Answer 1

Ubuntu:

sudo apt-get install python-wxtools

Answer 2

Windows:

1. Go to C:\Python27\Lib\site-packages\ find the folder wx-<version>-msw or similar

2. Move the wx from the above folder to C:\Python27\Lib\site-packages\

Answer 3

For Windows and MacOS, Simply install it with pip

pip install -U wxPython

Reference: Official site

Answer 4

I had the same error today but I tried something and surprisingly it worked. In the site packages folder there will be a file named wx.pth. Open it using notepad and its contents would be like "wx-2.8-msw-unicode"

It is basically the name of the folder containing wxpython. Delete this using Ctrl + A and copy the name of the folder from the site packages and paste it here even if it is the same.

Sounds weird but maybe the original file contained a hidden character...

Answer 5

I had the same problem for a PyMOL plugin that required the wx module, though I installed wxpython by downloading its package from here (Unofficial Windows Binaries for Python Extension Packages) and installing it with the command:

pip install .\wxPython-3.0.2.0-cp27-none-win_amd64.whl

For some reason it gave me that error, for which I uninstalled it with:

pip uninstall wxPython

and then I downloaded it from here (wxPython 4.0.0a1) and reinstalled:

pip install .\wxPython-4.0.0a1-cp27-cp27m-win_amd64.whl

The error at this point has not been presented anymore.

Answer 6

I too face the same problem, I like to share which I was faced so it can be helpful for anyone. In my case I have installed both python2. 7 and python3, and tested the application in python3 after some analysis I used

pip show wxpython-common

to find the location of wx which was in

/usr/lib/python2.7/dist-packages

so i understood in my case wx will work only in python2.7 environment

Answer 7

In fedora you can use following command to install wx

pip install -U \
  -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-16.04 \
  wxPython

Answer 8

If you do not have wx installed on windows you can use :

 pip install wx

Answer 9

I'm on 64-bit Windows 7 and went to:

https://wxpython.org/

Then downloaded the exe for my system, installed it, and it worked for me.

Answer 10

Download the .whl file from this link.

The name of the file is: wxPython‑3.0.2.0‑cp27‑none‑win32.whl for Windows 32 bit and python 2.7 and wxPython‑3.0.2.0‑cp27‑none‑win_amd64.whl for Windows 64 bit and python 2.7.

Then in the command prompt: pip install location-of-the-above-saved-file

Answer 11

This worked for me

pip install --user -U wxPython

Answer 12

You may check if you have the directory where are the packages of Python (in my machine, this dir is C:\Python27\lib\site-packages) in the Path variable on Windows. If Python's path environment variable does not have this directory, you will not find the packages.

Answer 13

Just open your terminal and run this command thats for windows users pip install -U wxPython

for Ubuntu user you can use this

pip install -U \
-f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-16.04 \
wxPython

Answer 14

I restart the IDLE and works for me!

Answer 15

Make sure you choose the right project intepreter in the compiler. I used the Pycharm, and I encountered the same problem. And it was solved by choose the right intepreter. Thisvideo may help you.

Answer 16

Generally, package names in the site-packages folder are intended to be imported using the exact name of the module or subfolder.

If my site-packages folder has a subfolder named "foobar", I would import that package by typing import foobar.

One solution might be to rename site-packages\wx-2.8-msw-unicode to site-packages\wx.

Or you could add C:\Python27\Lib\site-packages\wx-2.8-msw-unicode to your PYTHONPATH environment variable.
