The urllib module used by pip will automatically load proxy configuration from your OS.
In this case, this fails because you appear to have some malformed proxy configuration, in the proxy-bypass field. Verify that your proxy configuration is correct. On Mac, do so under System Preferences > Network.
Bypass proxy settings hosts section. i removed them and its working fine now. ----This worked for me as well
If #Martijn Pieters' answer doesn't fix it for you, be sure to check the "Bypass proxy settings hosts" section.
Try removing the addresses in that field, click apply changes and try again.

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:

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.

Requests can verify SSL certificates for HTTPS requests, just like a

And if you want to avoid the SSLError you can find the requests part and change verify to False:
requests.get('https://google.com', verify=False)
Another way reinstall certifi module:
sudo pip uninstall -y certifi
sudo pip install certifi==2015.04.28

edit: I tired reinstalling ubuntu, and I am still facing this error
Unset socks proxy, in your case:
unset all_proxy
unset ALL_PROXY
Install missing dependencies:
pip install pysocks
Reset proxy, source .bashrc, and pip install works again with socks proxy.
I was also not able to install Django and other stuffs after activating venv than I finally did this [1]
type: sudo gedit .bashrc #or any text editor if gedit is not there
add this line at the last of your .bashrc file
export all_proxy="https://your_proxy:your_port/"
save the changes it should work. Thanks
Ref. [1] https://stackoverflow.com/a/39959360/4706745
This is what worked for me pip install --user --proxy https://user:pass#proxyaddress:port django
Uninstall the installed package using
pip uninstall packagename
and set the proxy
http_proxy=http://username:password#host:port/
https_proxy=https://username:password#host:port/
and try to install using
pip install packagename

Thanks metjuf
There is a strange character in your command, most likely the result of some automatic conversion. I'm talking about – (U+8211, b'\xe2\x80\x93' as UTF-8). So instead of
pip install –pre youtube_dl_server
run
pip install --pre youtube_dl_server

How can I fix this?
pip 6.1.0 has been released, fixing this issue. You can upgrade with:
pip --trusted-host pypi.python.org install -U pip
to self-upgrade.
Original answer:
This is caused by a change in Python 2.7.9, which urllib3 needs to account for. See issue #543 for that project. Your OpenSSL libraries do not support SNI, which means urllib3 won't pass in the host name to the SSL socket wrapper, but Python 2.7.9 expects the hostname to be passed in anyway for different purposes.
urllib3 is indirectly used by requests (see requests issue 2435), which in turn is being used by pip.
I've opened a ticket to track this from pip's perspective.
The underlying issues have been fixed by the project maintainers, and awaiting a new release. You could install the current development version of pip if you are impatient:
pip install --trusted-host=github.com -U https://github.com/pypa/pip/archive/develop.zip
This'll install pip-6.1.0.dev0, when 6.1.0 is fully released you can upgrade again with pip install -U pip to get the final release from PyPI.
I get the same issue, and find that it can be avoided (pip 6.0.8) in my case as follows
pip --trusted-host pypi.python.org install <thing>
It is related to urllib3.
You can resolve it with urllib3 version 1.25.8.
Download that version of urllib3 manually and install it.
Even though you install thia version, pip will still use its own version.So you have to remove it and replace it.
Usually, installed module is on PythonXX/Lib/site-packages
Delete urllib3 in PythonXX/Lib/site-packages/pip/_vendor
Move "PythonXX/Lib/site-packages/urllib3" to "PythonXX/Lib/site-packages/pip/_vendor".
I encountered this problem and tried the above methods, but not work. I finally find it is because I turn on the VPN. When I turn off the VPN, I can successfully download packages.
