Cannot install python external package with pip main

Question

I have external package and i want to install it by code inside my app, the code looks like :

try:
    from pip import main as pipmain
except:
    from pip._internal import main as pipmain            

pipmain(['install', module])

# NOTE : module is string package's name

but there is an error like : TypeError: 'module' object is not callable

You're trying to use pip in a way that's not supposed to be used. Why would you expect it to work? — Marco Bonelli, Jan 16 '20 at 10:38
You can not call pip in a python script. If you want to do an automatic installation I'd recomend you to write a .bat — Ivan, Jan 16 '20 at 10:40
@Ivan You can install a package this way. Though it's not a good practice, generally — Henry Harutyunyan, Jan 16 '20 at 10:42
@HenryHarutyunyan module is just a string name of my own package, it's simillar like 'flask' — Mamen, Jan 16 '20 at 10:44
@HenryHarutyunyan i uploaded my own package with devpi so, my app can install it with external index url param, however the code above is working in 'flask run' environtment, but when i'm using uwsgi , the error is appears — Mamen, Jan 16 '20 at 10:46
@Mamen ohh, then you need to specify those in the question. How was I supposed to know that? — Henry Harutyunyan, Jan 16 '20 at 10:47
i found solution in this question https://stackoverflow.com/questions/58451650/pip-no-longer-working-after-update-error-module-object-is-not-callable but don't know how to implement it @HenryHarutyunyan — Mamen, Jan 16 '20 at 10:47
Should you use only pip main to install the modules from the program? I mean is there a restriction ? — Solen'ya, Jan 16 '20 at 12:04
@Solen'ya yes because i've tried with subproccess it didn't work either — Mamen, Jan 17 '20 at 03:25
@HenryHarutyunyan i've update, the code also didn't work for package from pypi.org ,it shows the same error — Mamen, Jan 17 '20 at 03:27
@Mamen can you use `os` to install by running `os.system("python3 -m pip install module")` — Solen'ya, Jan 17 '20 at 03:35
@Solen'ya i haven't tried it but thank you for your solution, i've just fixed it — Mamen, Jan 17 '20 at 03:42

So after figuring out what happen, i've found the answer in this github issue's comment

it should be pipmain.main() not pipmain()
