如果您命中了pip安装请求，并且已经满足了Requirement的输出消息，但仍然会收到错误：ImportError:No module named requests。

当您发现自己处于不同的口译员/虚拟环境中时，可能会发生这种情况。

您可以将模块的路径复制并附加到工作环境中。注意：此路径通常带有消息Requirement already confirmed

在导入请求之前，应该导入sys，然后追加复制的路径。

例子：命令提示符：pip安装请求输出：已满足要求：/usr/local/lib/python3.9/site-packages中的请求

import sys
sys.path.append("/usr/local/lib/python3.9/site-packages")
import requests 

如果要在windows上请求导入：

pip install request

然后美容组4：

pip3 install beautifulsoup4

对于windows，只需将路径作为cd和python的“脚本”路径，然后执行命令easy_install.exe请求。然后尝试导入请求。。。

遵循本教程：

Python常见安装问题

如果Homebrew在macOS上破坏了您的路径，这些命令也很有用。

python -m pip install requests

or

python3 -m pip install requests

并行安装多个版本的Python？

我已经安装了python2.7和python3.6

打开命令行~/.bash_profile，我发现#Setting PATH for Python 3.6，所以我将路径更改为path=“/usr/local/Cellar/python/2.7.13/bin:${path}”，（请确保您的python2.7路径），然后保存。这对我有用。
