ERROR: Could not find a version that matches requests

I ran:

$ mkdir test
$ cd test
$ pipenv install requests

but this caused the following error:

ERROR: ERROR: Could not find a version that matches requests
No versions found
Was https://pypi.org/simple reachable?

I thought this problem is due to proxy, but the following successfully run.

$ pip install requests

Please help me…

These steps solved similar issue I had recently:

Delete the virtual environment and pipfile(s)

$ pipenv --rm 
$ rm Pipfile
$ rm Pipfile.lock 

then reinstall project dependencies $ pipenv install package1 package2 package3

Why is this issue closed? This is still an issue on Windows. Are there any fixes for WINDOWS machines? Thanks.
