Question

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：

如何在.bash_profile中添加到python路径，以便它在开头。这是为共享主机。我需要能够导入我的django安装而不是使用系统默认值。

谢谢

Answer 1

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，则可以添加.pythonrc文件，并在显示交互式提示之前执行该文件。

Answer 2

我要说导入site模块时正在修改PYTHONPATH。请查看user模块以提供用户特定的配置（基本上只是将您感兴趣的目录添加到sys.path）。

注意：user模块目前已被弃用，但对于python 2.4，这应该可行。

编辑：为了完整起见，对于python＆gt; = 2.6（不建议使用user模块），您应该在本地usercustomize.py目录中创建一个site-packages文件，如所述{{3} }。

Answer 3

作为替代方法，您可以直接从解释器修改sys.path：

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

Answer 4

如其他人所示，您可以直接在Python中修改sys.path，如下所示：

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

但我认为virtualenv是您正在寻找的解决方案。此工具允许您创建隔离的Python环境。
