在windows 10上安装google助手时出错

Question

我试图在Windows 10上安装gogle-助手-sdk，但是我发现了一个奇怪的错误，我无法理解。

在为所有用户安装python并在运行以下命令时设置ENV变量后-

py -m pip install google-assistant-sdk[samples]

我跟错了-

Command ""C:\Program Files (x86)\Python37-32\python.exe" -u -c "import 
setuptools, tokenize;__file__='C:\\Users\\ramji\\AppData\\Local\\Temp\\pip- 
install-p29c8ggl\\grpcio\\setup.py';f=getattr(tokenize, 'open', open) 
(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, 
__file__, 'exec'))" install --record C:\Users\ramji\AppData\Local\Temp\pip- 
record-7znlf3rz\install-record.txt --single-version-externally-managed -- 
compile" failed with error code 1 in C:\Users\ramji\AppData\Local\Temp\pip- 
install-p29c8ggl\grpcio\

详细输出-

我甚至尝试在另一台windows 10机器上执行这个逗号，并得到了相同的结果。

有谁知道问题和解决办法是什么吗？

谢谢和问候。

Answer 1

看起来，编译某些依赖项需要构建工具：

需要MicrosoftVisualC++ 14.0。使用"Microsoft Visual C++ Build Tools“获得它：http://landinghub.visualstudio.com/visual-cpp-build-tools

Answer 2

不幸的是，用于MicrosoftVisualC++的独立构建工具已不复存在。相反，微软更喜欢你安装他们的6GB的视频工作室，许多旧的链接直接指向这个工作室。我们中的许多人意识到，这一要求是专制的，并希望独立安装程序回来。

下面的位置似乎承载了VS2015的构建工具。然而，它告诉我，它们的大小将在3gb到6gb之间：https://visualstudio.microsoft.com/vs/older-downloads/

对于C++构建工具来说，这个大小没有任何意义。然而，我被告知这是正确的。看起来，在真正的MS时尚，它带来了许多额外的行李，大多数用途，甚至不会关心。
