Archlinux pip and setuptools not upgraded

问题

Terminal command :

python -V output: Python 3.5.2

I'm trying pip and setuptools update on pycharm but this error occurred :

Error :python packaging tool 'pip' not found.

Proposed solution:

Try to run this command from the system terminal. Make sure that you use the correct version of 'pip' installed for your Python interpreter located at '/usr/bin/python3.5'.

Terminal command :

which pip output: usr/bin/pip

And I'm trying on terminal command :

pacman -S(or -Syu,-Syy) python-pip or pacman -S(-Syu,-Syy) python-setuptools

resolving dependencies...
looking for conflicting packages...

Packages (5) python-packaging-16.7-1 python-pyparsing-2.1.5-1
             python-setuptools-1:24.0.2-1 python-six-1.10.0-2

Errors occured, no packages were upgraded.

So I'm trying :

python -m pip install -U pip

Output :

/usr/bin/python: No module named pip

How to update pip ?

回答1:

This should work:

pacman -S --force python-pip and pacman -S --force python-setuptools

回答2:

It's not recommended to install python packages along with pacman. because pacman doesn't recognize any package installed by pip. I think you should remove all pip packages instelled using pip and reinstall all python packages using pacman or virtualenv. if you need python packages for arch you can search through AUR or you can install any python packages in a virtual environment.

回答3:

If you want the most up-to-date version from pypi and not from repository, then do something like

pip install -U pip
