Can't install python packages with pip


I am a python programmer and sometimes need install global packages (not always venvs), well about 1 month i have a permanently error when i try to install any package, by example:

sudo pip install pgcli

Collecting pgcli
Traceback (most recent call last):
File "/usr/lib/python3.6/site-packages/pip/_internal/", line 228, in main

inst = cls(resp.content, resp.url, resp.headers)
File "/usr/lib/python3.6/site-packages/pip/_internal/", line 753, in init
TypeError: parse() got an unexpected keyword argument 'transport_encoding'

The same with any package. There is no problem with pacman -S python-requests or with pip2 install pgcli and i have try reinstall the pip package.

Any ideas?

Taking as reference

sudo pip uninstall tensorflow (just in case, use only inside venv)
sudo pip uninstall html5lib
sudo pacman -S python-html5lib
sudo pip install html5lib
sudo pip install pgcli

Take a careful read :slight_smile:


Why does everyone who uses Python use sudo pip install and then not be able to fix it? :sob:


It appears you've found a Universal Truth. :sad:

Because they are all startup programmers and not sysadmins ? :japanese_ogre:
(but seriously ... this is like a 3 times a week topic..)

Sounds like another candidate for the big flashing red WARNING before it can be installed.

I'd almost be in favor of a warning, kickoff, point to docs, etc the first time sudo pip was used.
But on the whole I'm still conflicted about the idea of the system protecting users from themselves.

Where I see the major issue is that legitimate technical help requests can go and unanswered because they end up getting buried by a bunch of easily avoidable (but numerous) help requests. That becomes a real issue as Manjaro gets more popular and the volume of help requests increases daily.

Perfect example I just spotted a wifi help post from 15 hrs ago that I missed. I guess Jonathon re-categorized it, and it got bumped up. I totally missed it because of the volume of posts that is happening every day.

On Manjaro - and Arch + derivatives never install systemwide python packages using pip with sudo.

First check with Add/Remove Software app if your python package is available.

Packages starts with python- for Python 3 packages and python2- for Python 2 packages.

If you need a specific package for development purpose - always use the virtual environment wrapper.

sudo pacman -Syu python-virtualenvwrapper

Source the file /usr/bin/ in your .bashrc or .zshrc and create a virtual env

mkvirtualenv your-dev

Inside the virtualenv you can install packages with pip without messing with the systems python packages.

Some times I use a search for unanswered posts to see if I can provide insight.
