easy_install makes installing new packages extremely convenient. However, as far as I can tell, it doesn’t implement the other common features of a dependency manager – listing and removing installed packages.
What is the best way of finding out what’s installed, and what is the preferred way of removing installed packages? Are there any files that need to be updated if I remove packages manually (e.g. by
rm /usr/local/lib/python2.6/dist-packages/my_installed_pkg.egg or similar)?
There are several sources on the net suggesting a hack by reinstalling the package with the -m option and then just removing the .egg file in lib/ and the binaries in bin/. Also, discussion about this setuptools issue can be found on the python bug tracker as setuptools issue 21.
Edit: Added the link to the python bugtracker.
If the problem is a serious-enough annoyance to you, you might consider virtualenv. It allows you to create an environment that encapsulates python libraries. You install packages there rather than in the global site-packages directory. Any scripts you run in that environment have access to those packages (and optionally, your global ones as well). I use this a lot when evaluating packages that I am not sure I want/need to install globally. If you decide you don’t need the package, it’s easy enough to just blow that virtual environment away. It’s pretty easy to use. Make a new env:
virtual_envt installs setuptools for you in the new environment, so you can do:
You can even create your own boostrap scripts that setup your new environment. So, with one command, you can create a new virtual env with, say, python 2.6, psycopg2 and django installed by default (you can can install an env-specific version of python if you want).
To uninstall an
.egg you need to
rm -rf the egg (it might be a directory) and remove the matching line from
$ easy_install -m [PACKAGE]
$ rm -rf .../python2.X/site-packages/[PACKAGE].egg

If you have replaced a package with another version, then you can just delete the package(s) you don’t need by deleting the PackageName-versioninfo.egg file or directory (found in the installation directory).
If you want to delete the currently installed version of a package (or all versions of a package), you should first run:
easy_install -mxN PackageName
This will ensure that Python doesn’t continue to search for a package you’re planning to remove. After you’ve done this, you can safely delete the .egg files or directories, along with any scripts you wish to remove.
To list installed Python packages, you can use
yolk -l. You’ll need to use
easy_install yolk first though.
Came across this question, while trying to uninstall the many random Python packages installed over time.
Using information from this thread, this is what I came up with:
cat package_list | xargs -n1 sudo pip uninstall -y
package_list is cleaned up (awk) from a
pip freeze in a virtualenv.
To remove almost all Python packages:
yolk -l | cut -f 1 -d " " | grep -v "setuptools|pip|ETC.." | xargs -n1 pip uninstall -y
I ran into the same problem on my MacOS X Leopard 10.6.blah.
Solution is to make sure you’re calling the MacPorts Python:
sudo port install python26 sudo port install python_select sudo python_select python26 sudo port install py26-mysql
Hope this helps.
First you have to run this command:
$ easy_install -m [PACKAGE]
It removes all dependencies of the package.
Then remove egg file of that package:
$ sudo rm -rf /usr/local/lib/python2.X/site-packages/[PACKAGE].egg
All the info is in the other answers, but none summarizes both your requests or seem to make things needlessly complex:
For your removal needs use:
pip uninstall <package>
For your ‘list installed packages’ needs either use:
which can output more package details.
easy_install yolk or
pip install yolk)
For me only deleting this file : easy-install.pth
worked, rest pip install django==1.3.7
This worked for me. It’s similar to previous answers but the path to the packages is different.
