在python中找不到模块

我有如下目录结构：

MainDir --FooBar --foobar.py, __init__.py
         |
         Ltests -- foobartest.py, __init__.py

在Foobertest.py内部， 我在进口

从FooBar.FooBar.func_导入FooBar*

__init__.py in foobar contains from .foobar import *

tests文件夹中的init.py是空的

但是当我试着经营食品店的时候 我得到这个错误

No module named FooBar.foobar.func_in_foobar

我认为你可以用索林在这里给出的答案来解决这个问题-：

您可以在MainDir中创建一个主文件，如

main.py

，该文件可以访问所有目录。对于测试，我发现成功地使我的测试依赖于我的python项目，并使用setuptools开发模式将其正确地放入path

import os, sys, inspect
 # realpath() with make your script run, even if you symlink it :)
 cmd_folder = os.path.realpath(os.path.abspath(os.path.split(inspect.getfile( inspect.currentframe() ))[0]))
 if cmd_folder not in sys.path:
     sys.path.insert(0, cmd_folder)

 # use this if you want to include modules from a subforder
 cmd_subfolder = os.path.realpath(os.path.abspath(os.path.join(os.path.split(inspect.getfile( inspect.currentframe() ))[0],"subfolder")))
 if cmd_subfolder not in sys.path:
     sys.path.insert(0, cmd_subfolder)

 # Info:
 # cmd_folder = os.path.dirname(os.path.abspath(__file__)) # DO NOT USE __file__ !!!
 # __file__ fails if script is called in different ways on Windows
 # __file__ fails if someone does os.chdir() before
 # sys.argv[0] also fails because it doesn't not always contains the path
