ModuleNotFoundError: Could not find python module-CodePudding

I got an ModuleNotFoundError error as seen below:

sample % python3 sample1.py 
Traceback (most recent call last):
   File "sample1.py", line 4, in <module>
       from util_lib.helper1 import helper1_print 
ModuleNotFoundError: No module named 'util_lib' 
sample %

.../Testing/sample/:
            sample1.py (calls helper1.helper1_print())
 
 .../Testing/util_lib/:
        helper1.py (has helper1_print())

Codes

sample1.py:

import sys
sys.path.insert(0, '/Absolute/Path/Testing/util_lib')
from util_lib.helper1 import helper1_print
helper1_print()


**util_lab/helper1.py:**
def helper1_print():
        print("Helper 1 Print")

Am I missing something?

I still have error when I used relative path instead of absolute path, see below:

sample1.py

import sys

sys.path.insert(0, '../Testing')
from util_lib.helper1 import helper1_print

helper1_print()

Error:

sample % python sample1.py
Traceback (most recent call last):
  File "sample1.py", line 4, in <module>
    from util_lib.helper1 import helper1_print
ModuleNotFoundError: No module named 'util_lib'

CodePudding user response：

It seems there is an issue while you are inserting path to sys.path as I see sample and util_lib directories are subdirectories of Testing not API_Testing

So instead of

sys.path.insert(0, '/Users/pluu/PycharmProjects/API_Testing/util_lib')

try

sys.path.append("abs/path/to/Testing")
