Angular 5 – 未捕获的ReferenceError：未定义req

我最近将我的运行项目从Angular 4.4.3更新为Angular5.我根据更新指南将所有角度包更新到Angular 5.0.0.

另外,我还将角度CLI更新为1.5.0.从那时起,我在控制台中遇到以下错误：

polyfills.b8a5e5b….bundle.js:1 Uncaught ReferenceError: req is not defined
    at polyfills.b8a5e5b….bundle.js:1
    at polyfills.b8a5e5b….bundle.js:1
    at polyfills.b8a5e5b….bundle.js:1
    at Function.r.__load_patch (polyfills.b8a5e5b….bundle.js:1)
    at polyfills.b8a5e5b….bundle.js:1
    at c (polyfills.b8a5e5b….bundle.js:1)
    at Object.<anonymous> (polyfills.b8a5e5b….bundle.js:1)
    at Object.eFQL (polyfills.b8a5e5b….bundle.js:1)
    at n (inline.904a54f….bundle.js:1)
    at Object.TU+8 (polyfills.b8a5e5b….bundle.js:1)

我在这里错过了什么吗？

解决方法

删除node_modules并运行npm install.

这个对我有用.
