webpack 的 UglifyJSPlugin 一填参数就报错，怎么解决？

Question

正常运行的部分代码：

const UglifyJSPlugin = require('uglifyjs-webpack-plugin');

plugins: [

    new UglifyJSPlugin()

]

但是我一但给UglifyJSPlugin添加配置信息，运行就会报错，比如：

plugins: [

    new UglifyJSPlugin({

        warnings: false

    })

]

无论填什么都报错，不知道哪儿出问题了，求大神指点。

报错信息：

npm ERR! code ELIFECYCLE

npm ERR! errno 1

npm ERR! webpack02@1.0.0 pack: `webpack`

npm ERR! Exit status 1

npm ERR!

npm ERR! Failed at the webpack02@1.0.0 pack script.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
