无法在npm运行生成上缩减代码

Question

我已经完成了使用create-react-app创建的react应用程序，使用npm start在本地运行没有任何问题，但是当我尝试使用npm-build进行构建时

我在缩小代码时遇到错误。我已经尝试克隆我的项目并尝试构建它，我已经尝试创建一个测试项目并尝试npm build，并且没有任何问题，只有当我尝试构建我的完整项目时才会这样。

这是我的错误

Answer 1

您可能正在使用旧版本的react-scripts，请尝试升级到react-scripts@>=2.0.0

Answer 2

它似乎在你的一个依赖项的this line上爆炸了。浏览一下create-react-app代码库，我猜他们在Webpack配置中传递给UglifyJS的选项不会解析ES2015+。新的since包可能应该被Babelified来支持旧版本的Node和旧浏览器，因为人们通常不会Babelify他们的依赖项。

这个包似乎也不是浏览器友好的，它看起来是应该在服务器端使用的东西。
