荘の学習メモ

In my case, there are several python3.x version installed in my system before, and I had to type python3.x and sudo pip3 for developing the code every time, which disturbed me.  Here are the methods I tried to solve this problem. Now I am able to type only the python3 command for the newest python3.8 use and pip3 for installing modules without root privileges. python3.x ... -> python3 ... sudo pip3.x install ... -> pip3 install / python3 -m pip install ...  1. Install pip3 locally under /home/$USER/.local/bin/. $ wget https://bootstrap.pypa.io/get-pip.py $ python3 get-pip.py --user 2. Edit ~/.bashrc $ export PATH=$PATH:~/.local/bin $ export PYTHONPATH=$PYTHONPATH:/usr/lib/python3.8/dist-packages $ source ~/.bashrc 3. Delete redundant pip path or error: ModuleNotFoundError: No module named 'pip._vendor.retrying' will be reported. $ sudo rm -r /usr/lib/python3/dist-packages/pip Check: $ python3 --version * Difference between /usr/local and /usr/.local /usr/local is a place
