Question

我正在尝试在Windows 10上安装gogle-assistant-sdk，但收到一个奇怪的错误，我无法理解。

为所有用户安装python并在运行此命令时设置ENV变量后-

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

我遇到以下错误-

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-

我什至尝试在另一台Windows 10计算机上执行此命令，结果也相同。

有人知道这是什么问题和解决方案吗？

感谢和问候。

Answer 1

看起来像构建工具是必需的，以便编译某些依赖项：

需要Microsoft Visual C ++ 14.0。使用“ Microsoft Visual C ++生成工具”获取它：http://landinghub.visualstudio.com/visual-cpp-build-tools

Answer 2

不幸的是，用于Microsoft Visual C ++的独立构建工具不再存在。相反，Microsoft希望您安装他们的6GB视觉工作室，许多旧链接都直接指向该工作室。我们中的许多人意识到这一要求是分散的，因此需要独立安装程序。

以下位置似乎托管了VS2015的构建工具。但是，它告诉我它们的大小将在3gb和6gb之间： https://visualstudio.microsoft.com/vs/older-downloads/

对于C ++生成工具，大小没有任何意义。但是，我被告知这是正确的。似乎以MS真正的方式，它附带了很多额外的行李，大多数情况下甚至都不会在意。

在Windows 10
