Typescript找不到名字'IterableIterator' [英] Typescript Cannot find name 'IterableIterator'

问题描述

我在typescript中的代码有问题
经过tsc编译后，我遇到的错误就是找不到一些名字。

I have problem with my code in typescript After compile by tsc, I have errors like about cannot find some names.

app.ts(1,22): error TS2304: Cannot find name 'IterableIterator'.
app.ts(8,20): error TS2304: Cannot find name 'IteratorResult'.
app.ts(26,6): error TS2304: Cannot find name 'Symbol'.
app.ts(26,26): error TS2304: Cannot find name 'IterableIterator'.

我的代码是：

class Fib implements IterableIterator<number> {
    protected fn1 = 0;
    protected fn2 = 1;

    constructor(protected maxValue?: number) {}

    public next(): IteratorResult<number> {
        var current = this.fn1;
        this.fn1 = this.fn2;
        this.fn2 = current + this.fn1;

        if (this.maxValue && current <= this.maxValue) {
            return {
                done: false,
                value: current
            }
        }

        return {
            done: true
        }
    }

    [Symbol.iterator](): IterableIterator<number> {
        eturn this;
    }
}

fib = new Fib();
console.log(fib.next());

版本tsc是版本2.1.0-dev.20160716

version tsc is Version 2.1.0-dev.20160716

推荐答案

问题是，在运行tsc -t ES6 app.ts代码编译正确后，tsc无法看到我的tsconfig.json。

Problem was that tsc cannot see my tsconfig.json, after run tsc -t ES6 app.ts code was compiled properly.
