推荐答案

您需要将您的新目录添加到环境变量 PYTHONPATH 中，并用冒号与之前的内容隔开.在任何形式的 Unix 中，您都可以在适合您使用的任何 shell(.profile 或其他，取决于您最喜欢的 shell)的启动脚本中使用命令执行此操作，该命令再次取决于有问题的外壳；在 Windows 中，您可以通过系统 GUI 来实现.

You need to add your new directory to the environment variable PYTHONPATH, separated by a colon from previous contents thereof. In any form of Unix, you can do that in a startup script appropriate to whatever shell you're using (.profile or whatever, depending on your favorite shell) with a command which, again, depends on the shell in question; in Windows, you can do it through the system GUI for the purpose.

superuser.com may be a better place to ask further, i.e. for more details if you need specifics about how to enrich an environment variable in your chosen platform and shell, since it's not really a programming question per se.
