I am writing a small script to do multithreading examples, but I can’t get it to work outside the pycharm environment. When I run it in pycharm (community edition) it is able to install the concurrent.futures and execute the code perfectly. But since I want to see the threads in the resource manager I need to run it outside the pycharm.

Now my python on windows is 3.11:

python -V
Python 3.11.2
                                                                                                                                                                                                                                        
pip -V
pip 24.3.1 from C:Program FilesPython311Libsite-packagespip (python 3.11)
             

my python venv interpreter on pycharm is 3.11 too.

my code uses concurrent.futures module, and when I do it from pycharm it installs it correctly without issues.

and yet when I try to do it on windows it doesn’t work.

C:WINDOWSsystem32>pip install concurrent
ERROR: Could not find a version that satisfies the requirement concurrent (from versions: none)
ERROR: No matching distribution found for concurrent

I have tried the following:
Could not find a version that satisfies the requirement <package>

I dont know if the package name is wrong or something? But if the package name worked in pycharm it should work in pip as well right?

I also tried to downgrade to py 3.8 but I got the same error

C:/Users/jhg/AppData/Local/Programs/Python/Python38/scripts/pip install concurrent
    ERROR: Could not find a version that satisfies the requirement concurrent (from versions: none)

I tried to search concurrent on pypi but I see only a backport for python2, but if there is a backport for python2 where is the python 3 version and how did my pycharm know where to find it?

here is the pip install verbose output:
