如何将PYTHONPATH设置为多个文件夹 [英] How to set PYTHONPATH to multiple folders

问题描述

在〜/.bash_profile 文件(OS X)中，我将PYTHONPATH设置为指向两个文件夹:

In ~/.bash_profile file (OS X) I've set PYTHONPATH to point to two folders:

export PYTHONPATH=/Applications/python/common:$PYTHONPATH
export PYTHONPATH=/Applications/sitecustomize:$PYTHONPATH

即使将 sitecustomize 文件夹设置在第二行上(在/common 之后)第一条路径被忽略，我无法从第一行中定义的路径导入任何模块.要使两个文件夹都PYTHONPATH都变为Python，需要对上述语法进行哪些修改?

Even while sitecustomize folder is set on a second line (after /common) the first path is ignored and I am not able to import any module from the path defined in a first line. What needs to be revised in above syntax to make both folders PYTHONPATHish to Python?

推荐答案

附加路径，因此只有一个PYTHONPATH.

Append your paths so there is only one PYTHONPATH.

PYTHONPATH="/Applications/python/common:/Applications/sitecustomize:$PYTHONPATH"
export PYTHONPATH

然后 source〜/.bash_profile

或将它们导入到您的Python脚本中(这仅适用于添加到脚本中的脚本):

OR import them into your Python script (this would only work for the script added to):

import sys
sys.path.append("/Applications/python/common")
sys.path.append("/Applications/sitecustomize")
