I want to install pip in cygwin (Windows 10). When I try that I get the comment that the destination file is missing. So how can I choose file? Is there any way to see the entire file system in cygwin? I have, or so I thought, already installed pip from cygwin installation package but when I try to run pip (or virtualenv) from cygwin I only get back command not found. So, if the question seems confused then it reflects my state of mind accurately.
In CYGWIN it is best to install packages via the CYGWIN installation program. Even for other installation packages like pip.
Run the CYGWIN installation program again. Select the pip package you want. Currently, python3-pip and python2-pip are available.
Running this installation again only updates your current CYGWIN installation and does not hurt anything you have installed already.
