分析Vue取消eslint语法限制

这篇文章主要为大家详细介绍了分析Vue取消eslint语法限制，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随四海网的小编两巴掌来看看吧！

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：

代码如下：

➜ my-project npm run dev 
 
> bblee-app@1.0.0 dev /Users/bianlifeng/my-project
> webpack-dev-server --inline --progress --config build/webpack.dev.conf.js

Errors:

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

代码如下：

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。
