以用户身份执行脚本时,我已经安装了一些软件包.这些软件包是第一个用户软件包,因此python在脚本运行之前没有将~/.local/lib/python2.7/site-packages添加到sys.path中.我想导入那些已安装的软件包.但是我不能,因为它们不在sys.path中.
I've installed some packages during the execution of my script as a user. Those packages were the first user packages, so python didn't add ~/.local/lib/python2.7/site-packages to the sys.path before script run. I want to import those installed packages. But I cannot because they are not in sys.path.
如何刷新sys.path?
我正在使用python 2.7.
I'm using python 2.7.
推荐答案如如何使用Python设置sys.path,何时设置? sys.path借助内置的site.py模块进行填充.
As explained in What sets up sys.path with Python, and when? sys.path is populated with the help of builtin site.py module.
因此,您只需要重新加载它即可.您不能一步一步完成它,因为名称空间中没有site.总结一下:
So you just need to reload it. You cannot it in one step because you don't have site in your namespace. To sum up:
import site from importlib import reload reload(site)就是这样.
