如何获取Python模块的路径（不是sys.executable）

发布于 2024-10-17 08:46:12 字数 471 浏览 2 评论 0原文

我需要在 python 程序中获取 PyQt 库的路径。程序作为另一个应用程序的脚本运行，因此我

sys.executable = 'D:/program files/visum/exe/visum115.exe

实际 python 路径（以及 PyQt 库模块的路径），

Path = C:\Python25\Lib\site-packages\PyQt4\plugins

和我需要我正在尝试的

os.environ['PYTHONPATH']

但我不确定它是否可靠。

问候！

附言。我需要它能够插入插件：

qApp.addLibaryPath('C:\Python25\Lib\site-packages\PyQt4\plugins')

原文

I need to get Path for PyQt library in python program. Program is run as a script from another application, therefore my

sys.executable = 'D:/program files/visum/exe/visum115.exe

and I need my actual python path (and path for PyQt library module)

Path = C:\Python25\Lib\site-packages\PyQt4\plugins

im trying with

os.environ['PYTHONPATH']

but I'm not sure if it can be robust.

Regards!

PS. I need it to be able to plug plugins:

qApp.addLibaryPath('C:\Python25\Lib\site-packages\PyQt4\plugins')

您可以尝试加载模块，并在检查其 __file__ 属性后获取 .pyc 文件的路径。

例如这样：

import MODULE, os
path = os.path.dirname(MODULE.__file__)

问候，
哈！

you can try to load the module and after check for it's __file__ attribute to get the path of the .pyc file.

for example like this:

import MODULE, os
path = os.path.dirname(MODULE.__file__)

HTH!

您正在寻找的是sys.path：

>>> import sys
>>> sys.path
 ['',
 '/usr/lib/python2.7/site-packages/virtualenvwrapper.github-0.1-py2.7.egg',
 '/usr/lib/python2.7/site-packages/pycharm-debug.egg',
 '/usr/lib/python2.7/site-packages/Fom-0.9.2-py2.7.egg',
