任何建议将不胜感激。我已经安装了Visual Studio，就像它在错误中告诉我的一样，并且我还尝试将其安装在venv环境中，但是仍然无法正常工作，我在下面提供了完整的错误消息。
错误消息有点长，这是它给出的error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Community\\VC\\Tools\\MSVC\\14.23.28105\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2的最后一条消息，如上所述，我已经安装了Visual Studio，所以我不明白我是否将其视为需要创建的env变量。没错，从错误的外观来看，这听起来像是他们的丢失文件夹，如果是的话，我该如何解决呢？
谢谢

这里的问题是
c:\users\carl-\appdata\local\programs\python\python37\include\pyconfig.h(59): fatal error C1083: Cannot open include file: 'io.h': No such file or directory
pip在这里正在下载web3源，并尝试使用C:\Program Files (x86)\Microsoft Visual Studio中的Visual Studio附带的编译器对其进行编译
它失败了，因为它找不到与Windows SDK捆绑在一起的标头（另请参见this post），可以使用Visual Studio Installer安装该标头。只需选择“修改”，然后选择“单个组件”，然后安装“ Windows 10 SDK”。那应该可以解决您的问题
