I have Python 3.5 on my computer, installed on Windows, although the installation process selected pip, but in the command line after entering pip still can not succeed, try to try a method, finally solved the problem!
1, use the following statement to ensure that there is no more error reporting
python3.5 -m ensurepip
2, use pip -V command to view, still prompted no, continue to enter the following command to test whether available
python3.5 -m pip install readline
3, suspect that the environment may not be configured well, so update the pip to try!
python -m pip install --upgrade pip
Type in pip and now it works.
The above article to solve the problem that pip can not be used after the installation of Python is all that I have shared with you, I hope to be able to give you a reference, and I hope that you will support me more.
