详解Vue取消eslint语法限制

由于vue对语法的限制过于严格，以至于在我第一次编译运行的时候一直编译失败，当然也包括一些警告：

You may use special comments to disable some warnings.
Use // eslint-disable-next-line to ignore the next line.
Use /* eslint-disable */ to ignore all warnings in a file.

当然，这里的警告我是知道怎么回事，但是这个错误我就很不明白了，原来eslint是一个语法检查工具，但是限制很严格，在我的vue文件里面很多空格都会导致红线(红线可以关闭提示)，虽然可以关闭，但是在编译的时候老是会跳出来，所以能关闭是最好的了。

关闭方法：

在build/webpack.base.conf.js文件中，注释或者删除掉：module->rules中有关eslint的规则

module: {
 rules: [
  //...(config.dev.useEslint ? [createLintingRule()] : []), // 注释或者删除
  {
   test: /\.vue$/,
   loader: 'vue-loader',
   options: vueLoaderConfig
  },
  ...
  }
 ]
}

然后重新运行一下npm run dev或者构建命令 npm run build就可以啦。
