意外令牌：运算符>|更新或替换uglify-js以处理ES6？

问题描述

这是我第一次使用react构建一个框架应用，并且在cmd提示符下运行npm run-script build时遇到此错误。

Failed to compile.

static/js/main.9516bce8.js from UglifyJs
Unexpected token: operator (>) [./~/aframe/dist/aframe-master.js:57303,0][static/js/main.9516bce8.js:80512,32]

  },

根据我的研究，我猜测我使用的uglify版本不支持ES6 但是我在网上找不到任何可以帮助我更新或替换uglify-js来处理ES6的东西

解决方法

您可以使用

进行更新

npm update uglify-js

将软件包更新为满足版本标记的最新版本。

如果此新版本不起作用，则可以将其更新为特定版本

npm update uglify-js@3.0.5

或仅将其更新为最新版本

npm update uglify-js@latest

要小心，因为更新可能会破坏一些现有代码

terser-webpack-plugin使用webpack v4为我工作。它确实支持ES6 +
