Pip Install a List of Packages

Question

Relatively simple question, how does one pip install several packages/modules within a python script? I have a script that calls on other scripts, and several people use the main script. So when someone runs it, it needs to install or update all listed packages automatically.

I tried using the solution linked but was unable to get something working.

Below code,

# Implement pip as a subprocess:
package = ['os', 'time', 'glob2', 'selenium', 'chromedriver_binary',
           'time', 'datetime']
def install(package):
    subprocess.check_call([sys.executable, '-m', 'pip', 'install', package])

It doesn't. See above, might still be an error on my side. – Cordell Jones Feb 17 '22 at 18:51 — Cordell Jones, Feb 17 '22 at 18:51
`os`, `time`, and `datetime` are all python builtins – C.Nivs Feb 18 '22 at 14:30 — C.Nivs, Feb 18 '22 at 14:30

You should be getting an error here, because the list items in the call to check_call should be strings, but you're passing packages, which is a list of strings. I think you want:

subprocess.check_call([sys.executable, '-m', 'pip', 'install'] + package)

Here, we're appending the package list to the arguments, so we'll end up with a command line like:

python -m pip install glob2 selenium...

I get this error, CalledProcessError: Command '['C:\\Users\\GAS02224\\Anaconda3\\python.exe', '-m', 'pip', 'install', 'os', 'time', 'glob2', 'selenium', 'chromedriver_binary', 'time', 'datetime']' returned non-zero exit status 1. – Cordell Jones Feb 17 '22 at 19:28

You can't `pip install` a Python builtin like `os` or `time`. – larsks Feb 17 '22 at 19:37
