unknown property 'optimization'

Question

I'll trying to use uglify with webpack but got this error:

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
 - configuration has an unknown property 'optimization'. These properties are valid:
   object { amd?, bail?, cache?, context?, dependencies?, devServer?, devtool?, entry, externals?, loader?, module?, name?, node?, output?, performance?, plugins?, profile?, recordsInputPath?, recordsOutputPath?, recordsPath?, resolve?, resolveLoader?, stats?, target?, watch?, watchOptions? }

I have

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

and

optimization: {
        minimizer: [new UglifyJsPlugin()]
    }

在我的webpack.config.js中，看起来webpack无法识别“优化”？

Answer 1

也许您使用的是旧版的webpack版本（3？），并且可能需要将插件实例放在plugin属性中：

module.exports = {
    ...
    plugins: [new UglifyJSPlugin()]
};

始终尝试查找与您使用的版本匹配的文档，或者将webpack更新为较新的版本。当前版本为4.19.0（于2018-09-17）。
