Answer 1

tl;dr : use python3.8 or update requirement.txt versions.

More info :

The combination of (A) gevent==20.9, (B) windows 10, and (C) python3.10 does not have a prebuilt wheel. You can check this kind of stuff by going to pypi and looking what is offered for downloads ( https://pypi.org/project/gevent/20.9.0/#files )

I'm assuming that you will not be able to compile things from source yourself (it's a hassle), so you need to change (A), (B) or (C).

(A). Changing this means relaxing or updating the version requirements. For example gevent==21.12 does have a wheel for windows and python3.10

(B). Changing this means not using windows, probably not an option

(C). Changing this means using older python version. For example, python3.8 has a wheel for gevent==20.9.

Answer 2

gevent==20.9.0 probably doesn't support Python 3.10, you can downgrade to Python 3.8 or you can try to download and install the latest version of gevent - gevent 21.12.0 - see https://pypi.org/project/gevent/#downloads .

1. Go to requirements.txt and replace the line gevent==20.9.0 with gevent==21.12.0 .
2. After that you can try to install all dependencies: pip install -r requirements.txt

If the solution above doesn't help, try to manually install a gevent wheel:

1. Download greenlet wheel greenlet‑1.1.2‑cp310‑cp310‑win_amd64.whl from https://www.lfd.uci.edu/~gohlke/pythonlibs/#greenlet
2. Go to the local directory which contains downloaded greenlet wheel and install it

pip install greenlet‑1.1.2‑cp310‑cp310‑win_amd64.whl

3. Download gevent wheel gevent‑21.12.0‑cp310‑cp310‑win_amd64.whl from https://www.lfd.uci.edu/~gohlke/pythonlibs/#gevent
4. Go to the local directory which contains downloaded gevent wheel and install it

pip install gevent‑21.12.0‑cp310‑cp310‑win_amd64.whl

5. Finally you can remove gevent==20.9.0 from requirements.txt and install other dependencies: pip install -r requirements.txt
