I'm running Ubuntu 9:10 and a package called M2Crypto is installed (version is 0.19.1). I need to download, build and install the latest version of the M2Crypto package (0.20.2).
The 0.19.1 package has files in a number of locations including (/usr/share/pyshared and /usr/lib/pymodules.python2.6).
How can I completely uninstall version 0.19.1 from my system before installing 0.20.2?
You might want to look into a Python package manager like pip. If you don't want to use a Python package manager, you should be able to download M2Crypto and build/compile/install over the old installation.
To automatically upgrade all the outdated packages (that were installed using pip), just run the script bellow,
pip install $(pip list --outdated | awk '{ print $1 }') --upgrade
Here, pip list --outdated will list all the out dated packages and then we pipe it to awk, so it will print only the names.
Then, the $(...) will make it a variable and then, everything is done auto matically. Make sure you have the permissions. (Just put sudo before pip if you're confused)
I would write a script named, pip-upgrade
The code is bellow,
#!/bin/bash
sudo pip install $(pip list --outdated | awk '{ print $1 }') --upgrade
Then use the following lines of script to prepare it:
sudo chmod +x pip-upgrade
sudo cp pip-upgrade /usr/bin/
Then, just hit pip-upgrade and voila!
pip list --outdated
You will get the list of outdated packages.pip install [package] --upgrade
It will upgrade the [package] and uninstall the previous version.To update pip:
py -m pip install --upgrade pip
Again, this will uninstall the previous version of pip and will install the latest version of pip.
pip install package_name -U
pip install $(pip list --outdated --format=columns |tail -n +3|cut -d" " -f1) --upgrade
for i in $(pip list --outdated --format=columns |tail -n +3|cut -d" " -f1); do pip install $i --upgrade; done
$ pip install pipupgrade
$ pipupgrade --latest --interactive
pipupgrade helps you upgrade your system, local or packages from a requirements.txt file! It also selectively upgrades packages that don't break change. Compatible with Python2.7+, Python3.4+ and pip9+, pip10+, pip18+.
NOTE: I'm the author of the tool.
How was the package originally installed? If it was via apt, you could just be able to do apt-get remove python-m2crypto
If you installed it via easy_install, I'm pretty sure the only way is to just trash the files under lib, shared, etc..
My recommendation in the future? Use something like pip to install your packages. Furthermore, you could look up into something called virtualenv so your packages are stored on a per-environment basis, rather than solely on root.
With pip, it's pretty easy:
pip install m2crypto
But you can also install from git, svn, etc repos with the right address. This is all explained in the pip documentation
How can I completely uninstall version 0.19.1 from my system before installing 0.20.2?
In order to uninstall M2Crypto use
pip uninstall M2Crypto
I need to download, build and install the latest version of the M2Crypto package (0.20.2).
In order to install the latest version, one can use PyPi
pip install M2Crypto
To install the version 20.2 (an outdated one), run
pip install M2Crypto==0.20.2
Assuming one just wants to upgrade
pip install M2Crypto --upgrade # Or pip install M2Crypto -U
Notes:
Depending on one's Python version (here's how to find the version) one may use a different pip command. Let's say one is working with Python 3.7, instead of just using pip, one might use pip3.7.
Using sudo is considered unsafe.
Nowadays there are better practices to manage the development system, such as: virtual environments or development containers. The development containers allow one to put the entire development environment (be it modules, VS Code extensions, npm libraries,...) inside a Docker container. When the project comes to an end, one closes the container. There's no need to keep all of those requirements around in the computer for no reason. If you feel like reading more about it: Visual Studio Docs, Github.
