Python安装在本地目录。

我的目录树是这样的:

(local directory)/site-packages/toolkit/interface.py

我的代码在这里:

(local directory)/site-packages/toolkit/examples/mountain.py

为了运行这个例子,我编写了python mountain.py,在代码中我有:

from toolkit.interface import interface

我得到了一个错误:

Traceback (most recent call last):
  File "mountain.py", line 28, in ?
    from toolkit.interface import interface
ImportError: No module named toolkit.interface

我已经检查过系统了。这里有目录/site-packages。此外,我在工具包文件夹中有__init__.py.bin文件,以向Python表明这是一个包。我在examples目录中也有一个__init__.py.bin。

我不知道为什么Python无法在sys.path中找到该文件。什么好主意吗?会是权限问题吗?我需要一些执行许可吗?


当前回答

对我来说,这是件非常愚蠢的事。我使用pip3 install安装了这个库,但是我运行的程序是python program.py,而不是python3 program.py。

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。

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... ?

在linux服务器上尝试dos2unix script_name

(使用find命令删除所有pyc文件(如果有的话)。- name”*。佩克”删除)

如果你在Windows上使用脚本,重新运行

对我来说,将该文件作为模块运行很有帮助。

而不是

python myapp/app.py

使用

python -m myapp.app

这并不完全相同,但在某些情况下这可能是一种更好的方法。

这招对我很管用: 在父文件夹内创建__init__.py文件(在您的情况下,在site-packages文件夹内)。并像这样导入:

from site-packages.toolkit.interface import interface

希望对你也有用!
