问题描述

I tried installing Flask and a few packages using sudo in a virtual environment, but on trying to import Flask, it'll throw up an ImportError. 我尝试在虚拟环境中使用sudo安装Flask和一些软件包，但是在尝试导入Flask时，会抛出ImportError。 On installing the same packages with pip install though it works fine. 使用pip install相同的软件包时，尽管效果很好。 So what's the difference between these methods? 那么这些方法有什么区别？ I tried this on Ubuntu. 我在Ubuntu上尝试过。

Also, where does pip install these packages? 另外，pip在哪里安装这些软件包？ Looking through Stack Overflow I could only find questions that answer how to list packages installed by pip, but not where to find them (in context to the virtual environment) 通过Stack Overflow查看，我只能找到回答如何列出pip安装的软件包的问题，​​而不能找到在哪里找到它们的问题（在虚拟环境中）
