在使用webpack2.x打包时，出现下面报错（Unexpected token name «i», expected punc «;»）：

ERROR in app.js from UglifyJs
Unexpected token name «i», expected punc «;» [app.js:9461,13]
定位到的报错是：

function oneOf (value, validList) {
    for (let i = 0; i < validList.length; i++) {//此行报错
        if (value === validList[i]) {
            return true;
        }
    }
    return false;
}
看样子是UglifyJs压缩插件在遇到es6语法时出错了。但是项目中自己写的代码是有用babel编译的，上面报错的代码应该是来自vue的库。为什么这些代码没有经过babel编译后才执行UglifyJs压缩呢？

1）调试模式和日志的配置都在 config/app.php 配置文件中

 

2）打开调试模式

'debug' => env('APP_DEBUG', true)
 

3）laravel的日志默认已经打开了（不可以关），我们可以修改一下日志的记录方式（默认 single 单文件记录）

'log' => env('APP_LOG', 'daily')
PS：日志的记录方式有 single, daily, syslog, errorlog

 

4）设置报错级别（避免生成过多日志）

'log_level' => env('APP_LOG_LEVEL', 'error')
PS：config/app.php 文件里默认是没这个配置项的，要自己加，可以使用的值还有 debug, info, notice, warning, error, critical, alert, emergency
