如何从 python 中删除请求并在 pip 中安装

我需要在 pip 中引用请求，但它已经在 python 中安装了。

 Requirement already satisfied: requests in /usr/lib/python3/dist-packages (2.18.4)

我怎样才能将请求更改为 pip？

  • Ubuntu 版本：18.04.2 LTS
  • python3版本：3.6.8
  • pip 版本：pip 19.1.1 来自 /home/biggi/.local/lib/python3.6/site-packages/pip (python 3.6)

运行我的 python 脚本时出现错误

import requests 
ImportError: No module named requests

当我尝试：sudo pip install requests

The directory '/home/biggi/.cache/pip/http' or its parent directory is
not owned by the current user and the cache has been disabled. Please
check the permissions and owner of that directory. If executing pip
with sudo, you may want sudo's -H flag. The directory

使用sudo -H pip install requests解决了该问题：
