在*nix上，还要确保PYTHONPATH配置正确，特别是它具有以下格式:

 .:/usr/local/lib/python

(注意开头的.:，这样它也可以在当前目录上搜索。)

它也可能在其他位置，取决于版本:

 .:/usr/lib/python
 .:/usr/lib/python2.6
 .:/usr/lib/python2.7 and etc.

你正在阅读这个答案说你的__init__.py是在正确的地方，你已经安装了所有的依赖项，你仍然得到ImportError。

我也遇到了类似的问题，除了我的程序在使用PyCharm运行时运行良好，但当我从终端运行时出现上述错误。在深入研究之后，我发现PYTHONPATH没有项目目录的条目。所以，我设置PYTHONPATH每个Import语句在PyCharm上工作，但不是从终端:

export PYTHONPATH=$PYTHONPATH:`pwd`  (OR your project root directory)

还有另一种方法可以使用sys。路径为:

import sys
sys.path.insert(0,'<project directory>') OR
sys.path.append('<project directory>')

您可以根据希望搜索项目的顺序使用插入/追加。

我的观点是:

随地吐痰:

Traceback (most recent call last):
      File "bash\bash.py", line 454, in main
        import bosh
      File "Wrye Bash Launcher.pyw", line 63, in load_module
        mod = imp.load_source(fullname,filename+ext,fp)
      File "bash\bosh.py", line 69, in <module>
        from game.oblivion.RecordGroups import MobWorlds, MobDials, MobICells, \
    ImportError: No module named RecordGroups

This confused the hell out of me - went through posts and posts suggesting ugly syspath hacks (as you see my __init__.py were all there). Well turns out that game/oblivion.py and game/oblivion was confusing python which spit out the rather unhelpful "No module named RecordGroups". I'd be interested in a workaround and/or links documenting this (same name) behavior -> EDIT (2017.01.24) - have a look at What If I Have a Module and a Package With The Same Name? Interestingly normally packages take precedence but apparently our launcher violates this.

编辑(2015.01.17):我没有提到我们使用一个自定义启动器解剖这里。

在我的例子中，问题是我链接到调试python和boost:: python，这要求扩展名是愚息_d。pyd，不仅仅是愚愚。pyd;重命名文件或更新CMakeLists.txt属性修复了错误。

根据你对orip帖子的评论，我猜事情是这样的:

You edited __init__.py on windows. The windows editor added something non-printing, perhaps a carriage-return (end-of-line in Windows is CR/LF; in unix it is LF only), or perhaps a CTRL-Z (windows end-of-file). You used WinSCP to copy the file to your unix box. WinSCP thought: "This has something that's not basic text; I'll put a .bin extension to indicate binary data." The missing __init__.py (now called __init__.py.bin) means python doesn't understand toolkit as a package. You create __init__.py in the appropriate directory and everything works... ?

Does

(local directory)/site-packages/toolkit

有__init__.py?

为了让导入遍历你的目录，每个目录必须有一个__init__.py文件。
