Question

我正在设置MacBook Pro，并遇到了一些与Python版本和pip有关的障碍。

我尝试运行：

$ ./myscript.py
Traceback (most recent call last):
  File "./better_publishing.py", line 7, in <module>
    import requests
ImportError: No module named requests

但是当我尝试pip install时：

$ pip install requests
Requirement already satisfied: requests in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (2.22.0)
Requirement already satisfied: chardet<3.1.0,>=3.0.2 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from requests) (3.0.4)
Requirement already satisfied: certifi>=2017.4.17 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from requests) (2019.6.16)
Requirement already satisfied: idna<2.9,>=2.5 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from requests) (2.8)
Requirement already satisfied: urllib3!=1.25.0,!=1.25.1,<1.26,>=1.21.1 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from requests) (1.25.3)

pip版本：

$ pip --version
pip 19.3.1 from /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pip (python 3.7)

Python版本：

$ python --version
Python 3.7.5

希望得到一些帮助。谢谢！

Answer 1

如果您是我，我将尝试卸载模块并重新安装。这是命令：

$ pip uninstall requests
$ pip install requests

Answer 2

您是否尝试过查看请求是否以pip list列出？

如果是，那么您可以尝试pip uninstall requests。如果这也使您出错，则可以尝试在查找器中删除该程序包。

此后，我可以再次使用pip install <some_package>。

Answer 3

也许您必须将其添加到myscript.py的第一行

#!/usr/bin/env python

pip安装请求失败，因为它已经安装，但我也收到“ ImportError：无模块请求”
