User installed python modules

Question

On Linux, how do I see the list of all python modules that are installed by a specific user.

Where does

pip install --user install <module>

install?

Is there a way to identify modules installed by a specific user using tools other than pip except the ones that are individually downloaded which could be anywhere?

Answer 1

The --user switch, by default, installs into the site.USER_BASE location :

Path to the base directory for the user site-packages. Can be None if getuserbase() hasn't been called yet. Default value is ~/.local for UNIX and Mac OS X non-framework builds, ~/Library/Python/XY for Mac framework builds, and %APPDATA%\\Python for Windows.

You can override this by setting the PYTHONUSERBASE environment variable, as detailed in the User installs” section of the pip manual.

Answer 2

You should be able to see all your python modules (and versions) like this ( docs here ):

C:\Users\joe>pip freeze
Cython==0.19.2
Flask==0.10.1
Jinja2==2.7.1
MDP==3.3
MarkupSafe==0.18
PIL==1.1.7
