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：

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

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。
