pythonpycharmpypiconcurrent.futures

windows pip cant install concurrent due to 'could not find a version that satisfies the requirement' but pycharm can

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 Files\Python311\Lib\site-packages\pip (python 3.11)

my python venv interpreter on pycharm is 3.11 too.

pycharm interpreter 311 my code uses concurrent.futures module, and when I do it from pycharm it installs it correctly without issues. import the package

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

C:\WINDOWS\system32>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:

Solution

  • There is no PyPI package called concurrent meaning that you can't pip install any such package.

    What we have is concurrent.futures which is part of Python's standard library. You don't have to install it as it comes with your Python installation. You simply import concurrent.futures and use it.

    However for Python 2 users, there is a backport of the concurrent.futures standard library module to Python 2 available on PyPI called futures. Python 2 users can pip install futures and use it.
