如何获取python模块的路径(不是sys.executable)

Question

我需要在python程序中获取Path for PyQt库.程序作为另一个应用程序的脚本运行,因此我的

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

我需要我的实际python路径(和PyQt库模块的路径)

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

我正在尝试

os.environ['PYTHONPATH']

但我不确定它是否能够健壮.

问候!

PS.我需要它才能插入插件:

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

Answer 1

您可以尝试加载模块,并在检查它的__ file __属性后获取.pyc文件的路径.

例如像这样:

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

此致,HTH!

你在寻找的是sys.path:

>>> import sys
>>> sys.path
