It seems that pylint on MacOS is not doing anything at all. Here is what I get. I did install pylint by doing pip install pylint
$ pylint tunnel.py

You're mentioning that you're using pylint 1.4.4, which is quite old and won't work with Python 3.5.
You should upgrade to the latest releases of pylint/astroid, e.g. by doing pip install -U pylint.

I've been trying to set up a virtual environment for django using pipenv. I've installed pipenv and configured the path properly. When I run the following command
pipenv --version
I get
pipenv, version 2022.9.8
Which implies that pipenv is working.
But when I attempt to install django with the following command
pipenv install django
I get the following error.
C:\Users\Saifia>pipenv install django

I've been trying to figure this out the whole day and have tried various things but I'm new this and I can't figure out my mistake.
Any help will be greatly appreciated!
I was using virtualenv for virtualization and had to use pipenv to follow a tutorial and could not get pipenv to work. I had to uninstall virtualenv and pipenv and reinstall pipenv for it to work. I am still using pipenv but I do not like it virtualenv works better for me.
I think that the key to your problem is the last message in the traceback:
"ValueError: Not a valid python path: 'C:/Users/Saifia/anaconda3/Scripts/python.exe'"
Check and see if this file exists at this location.
If not, your default python version isn't set correctly in pipenv.
Deactivate any virtual environment and check your python version before you install pipenv.
It fails using pylint version 2.9.0 and 2.9.3. With version 2.8.3 it still works though.
See GitHub-issue under the provided link.

Installing pylint=2.9.3
Installing astroid and pylint (latest versions, no version specification)
Installing astroid and pylint and upgrade astroid to latest version during build-process (in AWS test-buildspec.yml) via pip install --upgrade astroid (suggested here)
It look like you found a bug/crash in pylint 2.9, you can open an issue here. You can downgrade to 2.8.3 while it's being fixed.
Thanks to the work of #Pierre.Sassoulas this issue has been resolved (see here).
After having proven that the following combination of pylint - and astroid - versions worked well together without producing the OP-error, new commits have been made to the GitHub-project to fix the problem:
pip install pylint==2.9.3
pip install git+git://github.com/PyCQA/astroid.git#c37b6fd47b62486fd6cbe77b913b568b809f1a6d#egg=astroid
From here going forward, the issue should not occur again installing the latest version of pylint combined with astroid. Yet, if the issue returns, I'll let you know here.

This exception comes up even for pip update commands. html5lib version is 0.999. The following code seems to be working fine.
import html5lib
document = html5lib.parse("<p>Hello World!")
Any pointers as to why this error is coming up would be helpful. Thanks in advance.
I was using anaconda and recently updated conda and anaconda and I recieved this error.
'conda update pip' fixed it
I'm trying to install twython, but keep getting errors.
First attempt:
pi#raspberrypi ~/twython $ sudo pip-3.2 install twython
Running setup.py egg_info for package requests
Traceback (most recent call last):
File "<string>", line 14, in <module>
File "/home/pi/twython/build/requests/setup.py", line 52, in <module>

Complete output from command python setup.py egg_info:

----------------------------------------
Command python setup.py egg_info failed with error code 1 in /home/pi/twython/build/requests
Next I searched on the last line of the error and followed some suggestions that said to make sure setuptools and ez_install were installed and up to date, but that didn't help.
Then I followed the backup instructions on ReadtheDocs that said to try to install it this way:
git clone git://github.com/ryanmcgrath/twython.git
cd twython
sudo python3 setup.py install
but it failed again:

It turns out that Twython cannot work with Python v3.2 because it depends on the requests module which apparently is not supported in Python 3.2.
One of the developers of Twython just explained this to me on Twitter.
