我正在使用Electron和serialport开发一个项目。

串行端口库不会自动工作。在 Readme.md 中搜索，我发现需要使用electron-rebuild库为 NodeJS 版本的电子重新编译库。（在 package.json 中插入这个脚本：）"install": "electron-rebuild"。

电子重建需要在计算机中安装 python，所以我通过windows-build-tools安装。（全局安装）

所以现在当我运行命令时，npm install我收到了这个错误：

我怎样才能编译这个库？提前致谢！

安装windows构建工具

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

或者

 npm --add-python-to-path='true' --debug install --global windows-build-tools

然后设置路径变量

setx PYTHON "%USERPROFILE%\.windows-build-tools/python27/python.exe"

set PYTHON

set PYTHON 可帮助您检查其设置是否正确。

在您的项目文件中全局安装电子重建是不够的

npm install -g electron-prebuilt  

npm install --save serialport

我们必须重建串行端口才能使用电子。为此，我们需要安装电子重建：

npm install --save-dev electron-rebuild

最后一步是再次在应用程序的根目录中运行 electron-rebuild：

 ./node_modules/.bin/electron-rebuild

serialport按照这些步骤，我设法在 Windows 10 x64 上为 Electron 1.4.14 编译。这在一周前有效，所以我不太确定在此期间是否发生了变化。

我首先需要 Windows 10 SDK、C++ 通用工具（包含在 Visual Studio Community 2015 中）electron-rebuild。Python 2.x 也是必需的。然后我安装electron-rebuild并serialport使用了 npm（使用 --save-dev 选项）。

然后我删除了node_modules/serialport/build/Release/*我的应用程序文件夹node_modules/.bin中的文件，最后转到项目中的文件夹并运行命令：

electron-rebuild -v 1.4.14 -e node_modules/electron-prebuilt -f我删除的文件再次出现，但为实际版本重建。请务必指定您正在使用的正确 Electron 版本。

这对我有用。

npm config set python /path/to/executable/python2.7

然后尝试。

npm install
