Python3.7-即使在sys.path中列出，也找不到模块

Question

I try to import some custom modules/packages but get the error "ModuleNotFoundError: No module named 'reader'".

I made sure that the absolute path to my custom package directory is listed in sys.path:

>>> os.getcwd()
'C:\\Python Projects\\reader'
>>> sys.path.append('C:\\Python Projects\\reader')
>>>
>>> sys.path
['', 'C:\\Users\\User\\AppData\\Local\\Programs\\Python\\Python37\\python37.zip', 'C:\\Users\\User\\AppData\\Local\\Programs\\Python\\Python37\\DLLs', 'C:\\Users\\User\\AppData\\Local\\Programs\\Python\\Python37\\lib', 'C:\\Users\\User\\AppData\\Local\\Programs\\Python\\Python37', 'C:\\Users\\User\\AppData\\Local\\Programs\\Python\\Python37\\lib\\site-packages', 'C:\\Python Projects\\reader']
>>>
>>> import reader
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'reader'

Also, all the paths listed in sys.path (except for '' and C:\\Python Projects\\reader) have been added in Environment variables > System variables (I am using Win10).

Is there something else I should to in order to successfully import custom packages in my projects?

Thank you

Answer 1

sys.path.append('C:\\Python Projects')

Then import reader will look for reader under 'C:\\Python Projects' , ie it will test for 'C:\\Python Projects\\reader' . Currently it's testing for 'C:\\Python Projects\\reader\\reader' .
