If you are behind a proxy  you must do some extra configuration steps before starting the installation  You must set the environment variable http proxy to the proxy address  Using bash this is accomplished with the command   export http proxy  http   user pass my site port      You can also provide the   --proxy  user pass  url port    parameter to pip  The  user pass   portion is optional

For myself  it turns out that wlan0 was down  which resulted in me being unable to connect out   So  ensuring that wlan0 was up  allowed pip   pip3 to work without issue

port 443 is not open  just allow custom tcp port 443 if on AWS else open the port 443 for the outbound connections

What happens here is that the the vendored versions of request urllib3 clash when imported in two different places  same code  but different names   If you then have a network error  it doesn t retry to get the wheel  but fails with the above error  See here for a deeper dive into this error   For the solution with system pip  see above   If you have this problem in a virtualenv built by python -m venv  which still copies the wheels from  usr share python-wheels  even if you have pip installed separately   the easiest way to  fix  it seems to be    create the virtualenv   usr bin python3 6 -m venv     install requests into the environment  this might raise the above error    lt venv gt  bin pip install requests remove the copied versions of requests which would be used by pip  rm  lt venv gt  share python-wheels  requests chardet urllib3 -  whl   Now a  lt venv gt  bin pip uses the installed version of requests which has urllib3 vendored

First of all  this problem exists because of network issues  and uninstalling and re-installing everything won t be of much help  Probably you are behind proxy  and in that case you need to set proxy   But in my case  I was facing the problem because I wasn t behind proxy  Generally  I work behind proxy  but when working from home  I set the proxy to None in Network settings   But I was still getting the same errors even after removing the proxy settings   So  when I did type   env   grep proxy   I found something like this     http proxy http   127 0 0 1 1234    And this was the reason I was still getting the very same error  even when I thought I had removed the proxy settings   To unset this proxy  type  unset http proxy   Follow the same approach for all the other entries  such as https proxy

check for network issues  to bypass the exception case code  In my case  I was using a custom index  that index had no route and such would trigger the exception case code  The exception case bug still exists and still masks the real issue  however I was able to work around this by testing the connectivity with other tools such as nc -vzw1 myindex example org 443 and retrying when the network was up

Just upgrade pip worked for me   pip install --upgrade pip

Bizarrely if I remove the proxy from the environment and add it to the command line it works for me  For example to upgrade pip itself   env http proxy  https proxy  pip install pip --upgrade --proxy  http   proxy-url 80    My issue was having the proxy in the environment  It seems that pip only honors the one in argument

Ubuntu comes with a version of PIP from precambrian and that s how you have to upgrade it if you do not want to spend hours and hours debugging pip related issues   apt-get remove python-pip python3-pip wget https   bootstrap pypa io get-pip py python get-pip py python3 get-pip py   As you observed I included information for both Python 2 x and 3 x

Solution      1   sudo apt remove python-pip     2  pip3 install pip  or install pip by get-pip py   Why  This error occurred on pip 8 0 1 which installed by apt-get  And happened only when your network is unstable     If you have a pip installed with apt  it hides the pip you installed by other ways  so you should remove the apt one first     I disconnected the network and tested 8 0 1  9 0 3  10 x the 3 versions installed with pip3 or get-pip py  no error occurred   nbsp  nbsp So  I think only the apt version of pip 8 0 1 has that bug  the others is ok
