动态模块导入在 python 中不起作用 - 为什么不呢？

Question

I'm trying to dynamically import a python script foo.py into another executable script, which is in a deeply nested folder. I'm using

import os
sys.path.insert(0, '../../../../.') 
from foo import Bar

this works, and I can use Bar happily.

I would like to make the script dynamically determine the folder depth eg

import os
root_path = os.path.relpath(os.popen("git rev-parse --show-toplevel").read()).replace("../reponame", ".")
print(root_path) # prints '../../../../.'
sys.path.insert(0, root_path)
from foo import Bar

However this doesn't work, the script complains it can't find Bar when it is run.

Why is this?

Answer 1

If you debug you see root_path is actually '../../../../.\n' . Remove the \n

root_path.strip()
