After update of Debian (Jessie), pytest doesn't work :

How can I fix this error? Thanx in advance!
The files in /usr/local/lib/python2.7/dist-packages belong to python packages you installed with pip, easy_install or python setup.py. The system update probably messed up some dependencies. Does this work?
sudo apt-get install python-pip
sudo /usr/bin/pip install -U pytest
Some instances might have more than one pytest running.
Try:
sudo apt-get remove pytest
Then run your test again.

I hope to install selenium to make crawling images, but this message makes me crazy. I can't googling this error as it is too long and I can't understand.
I tried to reinstall python with and pip with this code
$ curl -O https://bootstrap.pypa.io/2.7/get-pip.py
$ python get-pip.py
$ python -m pip install --upgrade "pip < 21.0"
I just started to study programming. Plz let me know what is wrong.
I just found what I did wrong.
I used pip instead pip3
With pip3, It works...
For someone in such a problem, I leave this post
I recently updated my Homebrew installation of Python 3.8.2 to 3.8.3. After doing so, I ran
$ pip3 install -U pip
in order to check for any pip updates. It updated my installation of pip from 20.0.2 to 20.1.1, and ever since I ran that command, pip throws an error any time I try to use it. Here's the error:

It seems that something went wrong during the upgrade process that failed to change the version check within the code. I saw this similar question, but the accepted answer is not working for me. How can I make pip usable again?
As per Python documentation, the correct way to use pip now would be via the correct Python executable, e.g.
python3 -m pip install -U pip
I had experienced a similar problem on my Ubuntu and here's how I solved my problem:
First restore the older version by reinstalling it from your OS package manager (You may need to uninstall first).
Upgrade to the latest version for your user (as opposed to installing in a system location) with the following command
pip3 install --user -U pip
Hope this helps.
I tried to download pip with easy install but after installation whenever I type pip into the mac terminal it gives me this error:

and when I try to do pip install pyopengl, it gives me the same error. What do I do to fix this?
Modern pip works with Python 2.6 and higher. It seems you got Python 2.5, so you either need to upgrade Python or use older version of pip.
According to the documentation Python 2.5 was supported through v1.3.1 of pip.
I installed fig on Arch Linux using the following command sudo pip install -U fig. After the installation was completed, I've tried to run fig --version but this gave me following errors:
Traceback (most recent call last):
File "/usr/bin/fig", line 5, in <module>

File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 626, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: fig==1.0.1
As it can be seen in the errors, I use python2. I also tried using python3, but I've got the same error.
Can anyone give me a hint?
You can try upgrading pip with easy_install:
easy_install --upgrade pip
Then try reinstalling fig.
I installed fig when python3 with set as default. After setting python2 as default, I've reinstalled fig and everything works now.
Upgraded to OS X 10.9 Mavericks and installed XCode, Command Line Tools, XQuartz, etc. Trying to run a pip install now, but it says that the distribution is not found:
Traceback (most recent call last):
File "/usr/local/bin/pip", line 5, in <module>
from pkg_resources import load_entry_point
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2603, in <module>

raise DistributionNotFound(req) # XXX put more info here
pkg_resources.DistributionNotFound: pip==1.4.1
So I tried to install pip with an easy_install. Turns out that's borked too:
Traceback (most recent call last):
File "/usr/local/bin/easy_install", line 5, in <module>
from pkg_resources import load_entry_point

raise DistributionNotFound(req) # XXX put more info here
pkg_resources.DistributionNotFound: setuptools==1.1.6
So some of the other threads say to reinstall setuptools with a sudo python ez_setup.py. It seems to work fine:
Installed /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/setuptools-1.1.6-py2.7.egg
Processing dependencies for setuptools==1.1.6
Finished processing dependencies for setuptools==1.1.6
But when running the easy_install pip, the same pkg_resources.DistributionNotFound: setuptools==1.1.6 error occurs. Anyone else have this problem? Any ideas how to fix this?
Install easy_install:
Download ez_setup.py module from https://pypi.python.org/pypi/setuptools
$ cd path/to/ez_setup.py
$ python ez_setup.py
Install pip:
$ sudo easy_install pip
try sudo python -m easy_install pip
I ran into a similar problem with git-review.
$ git review -s

The git-review team said it was a bug with pkg_resources that could be fixed with
sudo pip install --upgrade setuptools
This worked fine for me.
