To update pip:

Answer 4

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

Answer 5

I think the best one-liner is:

pip install --upgrade <package>==<version>

Answer 6

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.
