I'm trying to install matplotlib for python 3.6.3 using, but I keep getting this exception all the time. I have tried using the whl files too, to do it manually, but same result. I'm using this link to get the whl:
https://www.lfd.uci.edu/~gohlke/pythonlibs/#setuptools
Also tried Anaconda, and python 2.7,3.4 and 3.5, and still can't fix the issue.

Try upgrading pip
pip install --upgrade pip
You might have to use the full path to pip, if it's not in the PATH variable, like so:
C:\Users\Marcin\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pip install --upgrade pip
Edit:
After searching and finding some duplicates on the web (with no solutions), it seems to me it might have something to do with the path of your python installation.
Such as: duplicate 1, and duplicate 2.
Is there a reason its not installed on the default C:\Python36-32 folder?
You might want to download and install the windows msi installer for python in the recommended way, and see where that gets you.
Solution:
After OP's comment, it seems that moving Python to C:\ path (preferably with a clean install with windows .msi from python.org should fix this issue.

actually i am beginner, please tell me what to do, i am at the last step to finish my first website, and i need to install the pillow in order to make imagefield in my model.
could you help me Please?
First try the following-
pip install Pillow
If the above doesn't work, try the following-
pip3 install Pillow
Edit 1:
If pip is showing error, do the following-
1) Check which version of python you are using. The latest version is 3.8. See if the following shows any error?
python3
If the above command shows error, that means you may need to install the latest version of python from its website.
2) Check the pip version-
pip -V
# pip 20.0.2 from /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/pip (python 3.8)
python3 -m pip install --upgrade pip
The above should install the lates pip version (20.0.2). Then try to install Pillow with pip.
Good morining,
I was trying to install RabbitMQ in my Ubuntu18.04 but it was like brain surgery. I have decided to remove everything, but now when I try to install python packages with pip, the terminal return strange exceptions. I have similar problems when I try to compile a python script with visualStudio. I really appreciate your help. Stay tech!

I tried this method
cd /usr/lib/python2.7/dist-packages
sudo ln -s /home/pi/.local/lib/python2.7/site-packages/paho
But it still shows the same problem. This problem have been occuring for a long time and i did alot of research using various solution but the problem still remain the same. Apparently, anything regarding to pip installation i would face the traceback problem. I really need some help regarding this. Thank you!
I manage to solve the problem which is there is something went wrong with my OS installation, i was using NOOBS previously and now i tried to install the OS of "Raspbian Stretch with desktop" and now it is working perfectly fine.
I got this same error in previous days.
You should try this before installing paho-mqtt.
pip install --upgrade setuptools
please let me know if its work or not!
for more information, Go to Onion Docs

This seems like a bug in virtualenv. See how virtualenv.py limits versions of setuptools and wheel for Python 2.6, but not for pip. It must limit pip to version '<10' for Py 2.6. Please report the bug or better send a pull request.
Meanwhile create a virtualenv with --no-pip and later install pip into the virtualenv manually.
Try using pyenv. At least it claims to support versions of Python back to 2.1.3
I get this error whenever I try to install any module using pip, but easy_install work perfectly. I have no proxies configured in my Ubuntu 12.04 machine.
Previously it was working fine, just dnt know, how it stoped working suddenly.
This is error i get, while running sudo pip install <any_package_name>:
Exception:

AttributeError: '_socketobject' object has no attribute 'set_tlsext_host_name'
I found a potential solution here. Here's the relevant quote:
"That happend because Ubuntu 12.04 (that is my server's OS) has old pyOpenSSL library which not accept attribute 'set_tlsext_host_name'.
For fix that, you need to add dependence pyOpenSSL >= 0.13.
On Ubuntu for update pyOpenSSL use pip, you also need to install libffi-dev and remove python-openssl by apt."
$ sudo apt-get purge python-openssl
$ sudo apt-get install libffi-dev
$ sudo pip install pyOpenSSL
Let me know if this is unclear or if it doesn't work for you.
