vue-electron使用serialport时问题解决方案

报错如下：

Uncaught TypeError: Cannot read property ‘modules’ of undefined
at Object.eval (webpack-internal:///./node_modules/bindings/bindings.js:29)
at eval (webpack-internal:///./node_modules/bindings/bindings.js:223)

总结下来：webpack不能解析二进制什么的…github有讨论

系统：win10  
"dependencies": {
    "core-js": "^3.6.5",
    "electron-prebuilt": "^1.4.13",
    "serialport": "^9.2.1",
    "vue": "^2.6.11"
},
"devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "babel-eslint": "^10.1.0",

    "eslint-plugin-vue": "^6.2.2",
    "vue-cli-plugin-electron-builder": "~2.1.1",
    "vue-template-compiler": "^2.6.11"
},

解决方法：

const { IgnorePlugin } = require('webpack')
 
module.exports = {
  pluginOptions: {
    plugins: [
      new IgnorePlugin({
        resourceRegExp: /serialport/
      })
    ],
    electronBuilder: {
      nodeIntegration: true,
      externals: [
        'serialport'
      ]
    }
  }
}

app.allowRendererProcessReuse = false

重新运行即可
