无法从 python 包导入 python 模块

Question

I have this repository structure:

py_files_and_packages/ # normal folder 
    package/  
        module1.py # contains a class  
        module2.py

the __init__.py file of this package contains only __author__='my name'

The Problem:
I am trying to import the class from module1.py into model2.py. When I use
from package.model1 import model1
and rung the script(model2.py) within PyCharm it works. However, when I run it from the command line it doesn't find the package. The error message: ImportError: No module named 'my package's name' .

I tried many tricks I found on the web such as ( https://stackoverflow.com/a/22777011/2804070)but it didn't work.
I am using python-3.5.1 (installed locally), PyCharm 5.0.4 community edition, OS debian wheezy

Answer 1

the problom is that python can't find your package, because it is not in search path.

in model2.py, try to add the following before from package.model1 import model1

import sys
sys.path.append('/path/to/py_files_and_packages')

so it looks like this:

import sys
sys.path.append('/path/to/py_files_and_packages')

from package.model1 import model1

# your code here

Answer 2

在model2.py试试这个：

from module1 import your_class_name
