Via windows command prompt  run  pip list --outdated You will get the list of outdated packages  Run  pip install  package  --upgrade It will upgrade the  package  and uninstall the previous version      To update pip   py -m pip install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

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

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

The best way I ve found is to run this command from terminal  sudo pip install  package name  --upgrade   sudo will ask to enter your root password to confirm the action     Note  Some users may have pip3 installed instead  In that case  use  sudo pip3 install  package name  --upgrade

To automatically upgrade all the outdated packages  that were installed using pip   just run the script bellow   pip install   pip list --outdated   awk    print  1     --upgrade   Here  pip list --outdated will list all the out dated packages and then we pipe it to awk  so it will print only the names  Then  the        will make it a variable and then  everything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re confused  I would write a script named  pip-upgrade The code is bellow      bin bash sudo pip install   pip list --outdated   awk    print  1     --upgrade   Then use the following lines of script to prepare it   sudo chmod  x pip-upgrade sudo cp pip-upgrade  usr bin    Then  just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
