  brew install cmake
  

  zeromq vendor napi.h error unknown type name napi_callback_scope

• 问题：用electron-rebuild编译报错：zeromq vendor napi.h error unknown type name napi_callback_scope
• 原因：未深究
• 解决办法：无需解决，后续继续：

npm install
./node_modules/.bin/electron-rebuild

是可以正常启动Electron的。

.electron-gyp node v8.h error unterminated conditional directive #ifndef INCLUDEV8_H

• 原因：
  • 表面上是node的v8.h头文件有问题
    • 实际上：的确也是v8.h文件内容有问题
      • 此处内容不全，只有7000多行，实际上完整的文件大概1万多行
  • 但是根本原因在于：
    • 此处的node版本是v8.17.0
      • 最高支持的electron版本是2.0.18
        • 而当前设置的electron的版本是7.1.2
• 解决办法：去把electron版本从7.1.2改为2.0.18

修改后：

文件：electron_python/electron-python-example/.npmrc

npm_config_target="2.0.18" # electron version
npm_config_runtime="electron" # 为elelctron编译
npm_config_disturl="https://atom.io/download/electron" # 资源下载地址
npm_config_build_from_source="true" # 从源码编译

文件：electron_python/electron-python-example/package.json

{
...
  "devDependencies": {
    "electron": "^2.0.18",
...
  }
}

即可。
