Can anyone please help me with this?
Got it to work
rm -rf /usr/local/lib/python3.5/dist-packages/OpenSSL/
pip3 uninstall pyopenssl
easy_install pyopenssl
It happened to me as well. (I'm running Python 3.7 on MacOS Catalina with Anaconda).
So apparently that's a problem with either cryptography module. Even pip uninstall wasn't working.
You could use this link for finding out the location of the cryptography package and delete it. Once deleted, just do pip install --upgrade cryptography and it will just work fine.
But in my case that wasn't working. So here's what I did:
Activate your env which has this problem. That could be done using conda activate <env_name> or source <path_to_env>/bin/activate.
(If there's no env, just skip this step)
Next execute where python or just conda info --envs if you're using anaconda. This should give you the path to the python executable. In my case it was ~/opt/anaconda3 as the output for conda info --envs.
Next just cd into that directory and then remove (or move it somewhere else in case you want a backup) the ~/opt/anaconda3/bin/python/cryptography folder. Or you could even do find . | grep cryptography after cding in the particular env folder to know the exact location of the package.
Next execute pip install --upgrade cryptography. In case that didn't work, you could try the same with the pyopenssl package.
Hope it helped.

I uses PyCharm's terminal for the action below.
I was unable to install packages using pip. If I tried to install, it raises a error.

from pip._internal.cache import WheelCache
ModuleNotFoundError: No module named 'pip._internal.cache'
Looking at the error, I found it's related to "caches", And I wrote a program which deletes all files which contains "cache" in it's name a few days ago since my computer is full of cache before.
My question is: Is it possible to add back the pip cache file back?
Looking forward to replys and answers.

ModuleNotFoundError: No module named 'pip._internal.cache'
The error message "ModuleNotFoundError: No module named 'pip._internal.cache'" typically indicates that there is an issue with the version of pip that you have installed on your system. This error message occurs when the module 'pip._internal.cache' is not found in the version of pip that you are using.
To fix this error, you can try upgrading pip to the latest version by running the command:
pip install --upgrade pip
If the issue persists, you can try uninstalling and reinstalling pip using the command:
python -m pip uninstall pip
And then
python -m pip install pip
Alternatively, you can try installing the package using the following command:
python -m pip install package_name
It's also possible that you have multiple versions of python installed on your system, and the one you're using doesn't have pip package. In this case, you can try running the above command with the python version that has pip installed.
It's also a good practice to use virtual environments to keep the dependencies and packages isolated.
Please let me know if there's anything else I can help with.
As you python environment is broken, I'd recommend you to reinstall pip.
If that doesn't work, just reinstall python.
Also, better don't delete all files with a specific name-pattern.
You (as you see) just break programms with it.
Better delete all files in you temp folder (%temp% in windows)
I have been using PyQt6 for a while without a problem. Now I'm trying to do the exercises from a textbook, using pyqtgraph. It does not seem to come bundled with PyQt6 because the import statement failed. I tried installing it with:
pip install pyqtgraph
I tried various combinations of sudo, pip, pip3 (pip points to pip3), python/python3.8/python3.9 -m pip install pyqtgraph (python links to python3). I forced a reinstall of pip from a curl and deleted old site-package versions from .local. I even did a git clone pyqtgraph and tried to build it from scratch. Nothing worked. I always get the same error:

use pip install beautifulsoup4 instead of bs4
Currently BS4/Beautifulsoup4 is not compatible with Python 3.10 (probably will working in future)
BS4 Release was in Sep 8, 2021
https://pypi.org/project/beautifulsoup4/#history
Python 3.10 realease in: October 04, 2021
https://devguide.python.org/#status-of-python-branches
I would assume compatibility issues until BS4 will update.
Until then everything should work with 3.9 so I would go with that.

AttributeError: module 'lib' has no attribute 'Cryptography_HAS_TLSEXT_HOSTNAME'
The versions of my modules are set in a requirements.txt file, which did not change. I was running pyOpenSSL 19.0.0, with Python 3.6. I upgraded to pyOpenSSL 20.0.0 and the problem went away, but I am confused as to how this could happen unless the 19.0.0 version on PyPI was changed, as I've used fixed versions of this module for some time now.
Can anyone explain what happened here? I'd like to avoid anything similar in the future. Thanks.
The root cause for this issue is the latest cryptography-3.3 package which was released 20 hours ago; unfortunately, the pyopenssl-19 has a weird requirement (cryptography >=2.3) hence the pip install automatically upgraded the cryptography to 3.3.
We have both pip and pip3 installed. So the following sequence is what fixed it for me:
sudo apt update; pip install -U cryptography; sudo apt remove python3-openssl -y; sudo apt autoremove; pip3 install -U cryptography;
I think I found it. I didn't have the cryptography module in my requirements.txt, so it was upgraded to the latest version without upgrading pyOpenSSL which was in my requirements.txt file. Seems like some kind of dependency should have prevented this, but I'm updating my requirements.txt to include everything now.
There's a new cryptography 3.3.1 which fixes the issue
I am trying to install readthedocs in local system (Ubuntu 14.04 ) in python3 virtual env from the instructions given in this link
When I ran pip3 install -r requirements.txt , I got an error for Distutils2 . I removed that dependency as the distutils2 is no longer supported and assumed setuptools would suffice.

SyntaxError: Missing parentheses in call to 'print'
I understand from the above stacktrace that the code is in python2 and so print statement is different in python3 .
Does this mean that I have to install readthedocs in python2 virtualenv ?
Can't we host the docs of python3 projects in readthedocs in-house server ?
The read the docs code does not support Python 3 yet. The installation instructions explicitly say to use Python 2.7:
First, obtain Python 2.7 and virtualenv
However, it should still be possible to use your read the docs installation to host docs for Python 3 projects, since the instructions then say:
If you plan to import Python 3 project to your RTD then you’ll need to install Python 3 with virtualenv in your system as well.
