问题描述
我已经安装了开发所需的所有库.但是当我尝试在 Flask 虚拟环境中导入它们时，它说找不到模块".当我尝试在没有虚拟环境的命令提示符下运行 python 时，它会导入它们而没有任何错误.所以我得出的结论是虚拟环境需要重新安装所有库.我不想这样做，还有其他办法吗?
I already have all the libraries required for development installed. But when I try to import them in flask virtual environment, it says "Module not found".When I try to run python in command prompt without a virtual environment, it does import them without any error. So I have reached the conclusion that virtual environment needs all libraries installed again. I don't want to do that is there any other way?
推荐答案
如果您使用 --system-site-packages 标志，你可以使用全局安装的包.默认情况下，您不能.
If you create your virtualenv with the --system-site-packages flag, you can make use of globally installed packages. By default, you cannot.
