Question

我在加载 Angular 8 项目时遇到此错误 http://localhost:4200

Uncaught TypeError: Cannot read property 'bind' of undefined
        at new t (backend.js:31)
        at Object.<anonymous> (backend.js:31)
        at Object.<anonymous> (backend.js:31)
        at r (backend.js:1)
        at Object.<anonymous> (backend.js:31)
        at r (backend.js:1)
        at Object.<anonymous> (backend.js:31)
        at r (backend.js:1)
        at Object.<anonymous> (backend.js:31)
        at r (backend.js:1)

this.clearImmediate=t.clearImmediate.bind(t);else{this.nextHandle=1,this.tasksByHandle={},this.currentlyRunningATask=!1,this.canUseProcessNextTick()

Answer 1

确保t.clearImmediate是在调用.bind()方法之前定义的。
