You seem to be running pip behind a proxy, if so run `pip --proxy "put proxy here" install jupyterthemes` — Mohamed Ali JAMAOUI, Apr 15 '19 at 11:44

It looks like you'd need to add trusted hosts.

Check this GitHub thread out.

Something like:

sudo pip install --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org --upgrade --proxy=127.0.0.1:3128 jupyterthemes

I could not use this command to install because I got the error "Proxy URL had no scheme, should start with http:// or https://". Instead to get it to work I used the command without the proxy argument: ``pip3 install --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org geopy`` – Noah Friedman Nov 27 '22 at 04:12
Used all the --trusted-host=host.com wihtout the proxy part and solved it – gzcarlosrd Aug 02 '23 at 21:01

please check if date is set correctly. this error pops up usually when the time and date are different from that of the server.

I approve, this has failed like this to me just after midnight, when my local time is not sync with UTC because of timezone difference – tiborka Nov 14 '22 at 08:05

You may have a security software installed. Zscaler is usually the culprit in my case, but other security softwares may cause this error to be thrown. VnC's answer is usually a quick fix. See a permanent fix explained.

In summary you will need to create a configuration file pip.ini or pip.conf in Unix. You will need to include trusted hosts in the file like below:

# for system-wide configuration file
[global]
trusted-host = pypi.python.org
               pypi.org
               raw.githubusercontent.com
               files.pythonhosted.org

# per-user configuration file
[user]
trusted-host = pypi.python.org
               pypi.org
               raw.githubusercontent.com
               files.pythonhosted.org

# per-virtualenv configuration file
[site]
trusted-host = pypi.python.org
               pypi.org
               raw.githubusercontent.com
               files.pythonhosted.org

I'm on Windows OS. Refer to the documentation for your OS.

I think some packages need to be installed using administrator privileges on mac try this:

sudo pip install

on window:

you have to open cmd by running it as administrator. I mean right click on cmd, choose

run as administrator then pip install pkg name
