这是我的.bash_profile

PYTHONPATH=".:/home/miki725/django/django:$PYTHONPATH"
export PYTHONPATH

然后我打开 python,但是我在 .bash_profile 中添加的目录不是第一个:

如何添加到 .bash_profile 中的 python 路径,以便它位于开头。这是用于共享托管。我需要能够导入我的 django 安装而不是使用系统默认值。

谢谢

最佳答案

最好的办法是在运行时修改sys.path。在共享托管环境中,通常在 .wsgi 文件中执行此操作。你可以这样做:

import sys
sys.path.insert(0, '/home/miki725/django/django')

如果您将 export PYTHONSTARTUP=/home/miki725/.pythonrc 添加到 .bash_profile 中,则可以添加您的 .pythonrc 文件,并且它也会在显示交互式提示之前执行。
