Fixing “Permission denied:” errors¶
The purpose of this section of documentation is to provide practical
suggestions to users seeing a “Permission denied” error on pip freeze.
This error occurs, for instance, when the command is installed only for another user, and the current user doesn’t have the permission to execute the other user’s command.
To solve that issue, you can try one of the following:
Install the command for yourself (e.g. in your home directory).
Ask the system admin to allow this command for all users.
Check and correct the PATH variable of your own environment.
Check the ACL (Access-Control List) for this command.
