错误：加载程序...未返回html，当我使用webpack.optimize.UglifyJsPlugin时，HTML_WEBPACK_PLUGIN_RESULT被压缩

Question

这是我的配置文件片段：

new webpack.optimize.UglifyJsPlugin({
        exclude:'/.*\/node_modules\/.*/',
        compress: {
            unused: true,
            drop_console: false,
            drop_debugger: true,
            dead_code: true,
            properties: false,
            warnings: false,
            screw_ie8: false,
        },
        mangle: {
            screw_ie8: false,
        },
        output: {
            screw_ie8: false,
        },
        comments: false,
    })
   ...
   new HtmlWebpackPlugin({
        devscript: process.env.NODE_ENV === 'production' ? '' : scriptInject,
        filename: filename_ssr,
        template: template_ssr,
        inject: false
    })

错误是：

Html Webpack Plugin:
<pre>
  Error: The loader "/Users/xiexing/work/code/static.g.iqiyi.com/game/react/node  _modules/_html-webpack-plugin@2.30.1@html-webpack-plugin/lib/loader.js!/Users/  xiexing/work/code/static.g.iqiyi.com/game/react/node_modules/_html-webpack-plu  gin@2.30.1@html-webpack-plugin/default_index.ejs" didn't return html.
</pre>

但是，如果我删除了webpack.optimize.UglifyJsPlugin，那么一切都会正常运行，并且会使用源代码进行调试。并发现其中有一个source变量的值是js文件的代码，例如：var HTML_WEBPACK_PLUGIN_RESULT ...，该js已被压缩，如果我删除webpack.optimize.UglifyJsPlugin，则该js将被解压缩并正常工作。 / p>
