Everytime I try to install a package using pip it shows an error

Question

Installing jupyter notebook. Everytime the same error occurs. And the error is the same if I install any other package too. I am currently using python 3.6.5 version which is the latest one. I have recently downloaded python and my windows version is 10.

Answer 1

I could install packages using: pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org <package_name>

Answer 2

Thanks for the help people. It was a silly fault at my side. I accidentally messed up my PATH variable. It's working just fine now after I corrected the path. :) Thanks a lot!

Answer 3

This seems be to be a known issue with pip. See https://github.com/pypa/pip/issues/5309.

I suggest you install Anaconda, it will take care of all these dependencies. It comes preinstalled with jupyter and some other python libraries like numpy, pandas.

Answer 4

It's not an issue with pip,it's an error with your firewall/network. Try allowing python3.exe through the firewall and run the terminal as an administrator. I just ran pip install jupyter in my terminal, it installed perfectly.

Also update your pip with

python.exe -m pip install --upgrade pip

Also, run

ping files.pythonhosted.org

in your terminal to make sure you can connect
