标签： javascript python node.js npm electron

【解决方案1】：

根据您提供的日志，它说构建脚本找不到 Python。 Electron 使用 node-gyp 构建自身，需要安装 python 和 Visual Studio 构建工具。

我建议你在npm 上安装windows-build-tools。它可以使用命令npm install --global windows-build-tools 安装。

【解决方案2】：

原因是您的模块使用 node-gyp - https://github.com/nodejs/node-gyp - 而 node-gyp 需要平台编译器。在此处阅读有关这些要求的更多信息：https://github.com/nodejs/node-gyp

如果您的开发者机器运行的是 Windows，您可以安装所需的编译器：

npm install --global --production windows-build-tools
