When I run python pip on a new brand Ubuntu 15.04 system with all updates installed, I get the following assertion error. This is with Python 2.7.x. I get a very similar result with Python 3.4.x:
➜ pip list
adium-theme-ubuntu (0.3.4)

pyOpenSSL (0.13.1)
pyserial (2.6)

I think you should report this as a bug here. I can reproduce it in my Ubuntu 15.04 (64bit). The man page clearly states the pip list and pip3 list commands should simply list the packages, but in both cases they crash with AssertionError before completing.

Suggestions please, thanks :)

I solved this problem updating pip, i updated from pip 20.3.4 to 21.3
so just type:
pip install pip -U
Seems like there is some bug in pip itself.
I've done some analysis of this bug in in the Debian bugtracker.
It appears to be a race-condition triggered by the way Debian was packaging pip until recently. Dependencies were zipimported from wheels instead of vendored in the source tree, as upstream does.
This should already be resolved in Debian >= 12 (bookworm) and Ubuntu >= 22.04 (jammy).
An updated for pip in Debian 11 (bullseye) is in progress.
Not a fix, but a solution of sorts:
I 'fixed' this by updating every package.
for f in `pip list | tail -n +3 | cut -d' ' -f1`; do
pip install --update "$f";
done
I found OP's problem while logged-in as root and immediately after upgrading to Debian 11; dunno if that's significant.
I'm kind of new in the programming world, and I've heard that pypy3 is 7x faster than python while running code, so I decided to give it a try. I created a bot to farm EXP on the game Yu-Gi-OH! duel links and wanted to run it with pypy3, however I need to install opencv and every time I try to do so I get this error .
commands I ran:
git clone https://github.com/skvark/opencv-python
cd opencv-python
pypy3 setup.py install
Error I got:

This is not actionable for me: I'm not certain what to fix/ how to proceed. Hints?
Note: in the meantime I have installed version 0.10.1 as follows:
sudo pip3 install 'datatable==0.10.1'
This has important by (expression based groupby) and sortvalues() that I need
Most likely this error occurs because you're trying to build datatable using an old version of pip. In order to build datatable from source, pip version 20.0 or higher is required.
Unfortunately, there is no way for a project to specify that it needs a specific minimum version of pip. And I presume if such setting would eventually be added, only the newest versions of pip would know about it anyways, defeating the purpose.
I have just installed Python 3.4.3 on my MAC (Yosemite). I need to install a couple of lxml, however everytime I type in: pip install /""/, I get error messages.
I have followed multiple tutorials and pip is installed.
MAC already had Python 2.7., but I installed the 3.4.3. version, not sure if that is the issue.
The error message is:

try:

I have similar issue with pip install. However, if I do "sudo su -" then do my pip install 'fileName', that solve the problem for me.

a few of our free packages had been flagged as "commercial" by mistake. We fixed the problem and you should be able to install them now.
Sorry about the trouble!
