The cause in my case was having a jupyter notebook open, which was importing the relevant library; the root cause seems to be windows error due to the file being open / in use (see also @Robert's answer, and the recommendation to reboot).

So another thing to verify is that no other python processes are running.

For me, shutting down the notebook server solved the issue.

I met a similar problem But the error report is about    SSL  TLSV1 ALERT ACCESS DENIED  tlsv1 alert access denied   ssl c 777    First I tried this https   python-forum io Thread-All-pip-install-attempts-are-met-with-SSL-error pid 28035  but seems it couldn t solve my problems and still repeat the same issue   And Second if you are working on a business computer generally it may exist a web content filter but I can access  https   pypi python org through browser directly  And solve this issue by adding a proxy server   For windows open the Internet properties through IE or Chrome or whatsoever  then set valid proxy address and port and this way solve my problems  Or just adding the option pip --proxy  proxy-address  port install mitmproxy But you always need to add this option while installing by pypi   The above two solution is alternative for you demand

One additional thing that has not been covered in previous answers and that often cause issues on Windows and stopped me from installing some package despite running as admin is that you get the same permission denied error if there is another program that use some of the files you  or pip install  try to access  This is a really stupid  feature  of Windows that pops up many times  e g  when trying to move some files   In addition I have no clue how to figure out which program locks a particular file  so the easiest ting to do is to reboot and do the installation before starting anything  in particular before running e g  Spyder or any other Python-based software  You can also try to close all programs  but it can be tricky to know which one actually holds a file  For a directory for example  it is enough that you have an Explorer window open at that directory
