Question

我只是想在Python中安装aiohttp。 所以我只是在控制台中输入： pip install aiohttp 。 一开始安装很顺利，但最后却出现了以下错误。

C:\Users\1\AppData\Local\Programs\Python\Python312\Scripts>pip3 install aiohttp

  note: This error originates from a subprocess, and is likely not a problem with pip.

所以我尝试了另一种“pip install pyproject”。 但我无法解决。 请帮助我！

Answer 1

您的错误消息显示：

Microsoft Visual C++ 14.0 or greater is required.

因此您应该使用“Microsoft C++ Build Tools”获取它：https://visualstudio.microsoft.com/visual-cpp-build-tools/`

另请注意，aiohttp 目前支持 Python 3.8 - 3.10，但您似乎使用的是 Python 3.12。
