添加到python path mac os x [英] Add to python path mac os x

问题描述

我想

import sys
sys.path.append("/home/me/mydir")

正在将目录附加到我的pythonpath

is appending a dir to my pythonpath

如果我打印sys.path，我的目录就在其中.

if I print sys.path my dir is in there.

然后我打开一个新命令，它不再存在.

Then I open a new command and it is not there anymore.

但是Python不能以某种方式导入我保存在该目录中的模块.

But somehow Python cant import modules I saved in that dir.

我在做什么错了?

我阅读了.profile或.bash_profile将解决问题.

I read .profile or .bash_profile will do the trick.

我是否必须添加:

PATH="/Me//Documents/mydir:$PYTHONPATH"
export PATH

要使其正常工作?

推荐答案

对sys.path的修改仅适用于该Python解释器的生命.如果要永久执行此操作，则需要修改PYTHONPATH环境变量:

Modifications to sys.path only apply for the life of that Python interpreter. If you want to do it permanently you need to modify the PYTHONPATH environment variable:

PYTHONPATH="/Me/Documents/mydir:$PYTHONPATH"
export PYTHONPATH

请注意，PATH是可执行文件的系统路径，它是完全独立的.

Note that PATH is the system path for executables, which is completely separate.

**您可以在~/.bash_profile中编写以上内容，并使用source ~/.bash_profile

**You can write the above in ~/.bash_profile and the source it using source ~/.bash_profile
