Python pip安装web3未安装

如有任何建议，将不胜感激。我已经安装了visual studio，就像它在错误中告诉我的那样，我还尝试在venv环境中pip安装它，但是它仍然不起作用。我在下面包含了完整的错误消息

错误消息有点长这是它给出的最后一条消息

error:command'C:\\Program Files（x86）\\Microsoft Visual Studio \\2019\\Community\\VC\\Tools\\MSVC\\14.23.28105\\bin\\HostX86\\x64\\cl.exe“失败，退出状态为2

，如前所述，我已安装Visual Studio，因此我不明白我是否已将其视为一个需要创建的环境变量。从外观上看，它似乎是一个丢失的文件夹错误，如果是，我该如何着手解决此问题

多谢各位

pip

在这里所做的是下载

web3

源代码，并尝试使用visual studio在

C:\Program Files（x86）\Microsoft visual studio中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
（另请参见）捆绑在一起的头文件，您可以使用
Visual Studio安装程序安装这些头文件。只需选择“修改”，然后选择“单个组件”，然后安装“Windows10SDK”。这应该可以解决你的问题了
看起来你在使用python3.7，你能尝试一下
pip3安装…
而不是
pip安装…
hummm谢谢你刚才给我的建议“pip3安装web3”但不幸的是，它导致了同样的错误。如果我使用pip3，这是否意味着我需要将python版本降级到3？我只是看了一下，它说它支持Python3.6+，没有pip3适用于任何Python3+，无论是3.5还是3.7。另外，你已经安装了python3.7，所以应该不会有问题。谢谢你，我刚刚在python3.6上提供了它，以防3.7不适用于web3。您是否对我如何修复此错误有任何想法？谢谢您的帮助，我刚刚修改了visual studio并安装了“visual studio SDK”和Windows 10 SDK（10.0.16299.0），但是重新启动后，我仍然收到相同的错误。他们的VS是否还有其他东西我也应该尝试安装？感谢我，
io.h
位于
C:\Program Files（x86）\Windows Kits\10\Include\10.0.16299.0\ucrt
安装
10.0.16299.0 SDK
后，您能检查一下该文件夹是否也存在吗？哦，是多么有趣啊！下面是io.h#pragma once#define#INC#io#include managed中的代码，通过安装just-able everything in VS Thank使其工作！
