How import module in PyCharm

Question

I have two projects. In first one, I can import my module importme.py like:

import importme

And now I can use my function hello() in importme module without any problem. In second one, I recieve:

ImportError: No module named 'importme'

But I can import it via:

from . import importme

Why I cant import my module the same way in both projects? Should I configure some paths ?

EDIT1:

Directory structure of first project:

testproject/
├── importme.py
└── start.py

Directory structure of second project:

spiders/

file init.py is empty.

Please add some overview on directory structure. And probably yes, there is something like `PYTHONPATH`. — Take_Care_, May 01 '18 at 11:28
so as You can see second project is package, so You should import it like this `from spiders import importme` . I just guess this *not working* one is this with `__init__` — Take_Care_, May 01 '18 at 12:07

I import it from the same directory as main program is. In start.py I import importme.py. inspider.py I import importme.py. so what is the difference? — dorinand, May 01 '18 at 12:19
First one as `python3 start.py`. Second one is run as `scrapy crawl `. — dorinand, May 01 '18 at 14:44

My favorite method of dealing with PYTHONPATH is installing package in edit mode in virtual environment.

Creating virtual environment

# create
$ python -m venv ~/virtualevns/myenv
# then activate it
$ source ~/virtualenvs/myenv/bin/activate
# you can check whether it got activated
$ which python
home/user/virtualenvs/myenv/bin/python

Writing setup.py for your project. For this refer to the official distributing packages tutorial.
Installing package in editable format.

If you install package with -e flag pip will install it in editable format meaning all changes you have in code will be present in your environment's package:
```
$ cd mypkg
$ pip install -e .
```
Finally you need to set your virtual-environment to be used in whatever IDE your editor you are using.

This is a great workflow because it's clean and reliable - you are using exactly what you'd be using in production/finished package environment.

I am using venv, but the problem is, that in first example, I can import module but in second one I cant. So my question is, why, where is the difference and how to solve it. — dorinand, May 02 '18 at 10:15
