pip 安装 web3 未安装

Question

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 环境中安装 pip，但是它仍然无法正常工作，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如前所述我已经安装了 Visual Studio，所以我不明白我已经将它视为我需要创建的环境变量没有avalie，从错误的外观来看，这听起来像是一个丢失的文件夹，如果是这样，我该如何解决这个问题？

谢谢

Answer 1

只需安装 cython

pip install cython #in the same environment

Answer 2

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在这里做的是下载web3源代码并尝试使用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（另请参阅这篇文章），您可以使用Visual Studio Installer这些标头。 只需 select“修改”，然后“单个组件”并安装“Windows 10 SDK”。 那应该可以解决您的问题

Answer 3

不确定我的问题是否相同，但下载 Microsoft C++ 构建工具对我有用

Answer 4

在 Windows 10 上，我尝试安装 Microsoft Visual C++ 构建工具，但这并没有解决问题。 所以我安装了一个基于 Linux 的系统，将其用作双引导，它可以工作。
