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... ?

使用PyCharm (JetBrains套件的一部分)，你需要定义你的脚本目录为Source: 右键单击>将目录标记为> Sources Root

通过编写print (sys.path)修复了我的问题，并发现尽管清洁安装，python仍在使用过时的包。删除这些会使python自动使用正确的包。

我也犯了同样的错误。这是由于有人在与我的脚本相同的文件夹中创建了一个文件夹，该文件夹的名称与我从其他地方导入的模块冲突。它没有导入外部模块，而是在这个显然不包含预期模块的文件夹中查找。

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。
