Configure environment/path to run python scripts from terminale. For Mac

Question

I found that when I run my scripts from environment - everything is OK.

But, when I try to run them from bash - I receive different errors with import modules. (ModuleNotFoundError, ImportError)

I didn't set the environment at all, so, please, tell me, what I should configure to succeed with it.

I use python 3.7

Received the next error:

Traceback (most recent call last): 
File "main.py", line 1, in <module> from package_3.file3 import * 
ModuleNotFoundError: No module named 'package_3'

The structure is:

package_1
   file1.py
package_2
   file2.py
package_3
   file3.py
package_4
   file4.py

Could you provide some more details? What version of python are you using (in what you refer to as 'the environment')? What errors are you getting? also, run 'which python' in the shell, and provide the results. — Roy2012

To help, one really needs to see exactly what you're seeing. What command do you run when you get this error? What's the current directory? What's the exact file structure? You're getting a message about package_suits, but your file structure doesn't contain any such file or directory. — Roy2012

I change directory to mine and run command: python3 package_4/file4.py — Vas23Vewe

What happens is, probably, that your working environment is python3, and when you run things in the shell, it's using python2. To solve it, run your script with python3 in the shell, as in:

python3 my_script.py

what do you see when you run "python3 --version " and "which -a python3" ?

And what version do you use in the environment where it does work? (what do mean by 'environment', by the way)?

When you run this in your environment, what do you get: import sys; print(sys.version_info)

and another thing to check - run "print(sys.argv[0])" in your environment.

so you're using PyCharm. Which Python interpreter is configured there (see this page: jetbrains.com/help/pycharm/configuring-python-interpreter.html)?
