从 rxjs 导入时出现意外令牌

Question

我在 main.ts 的打字稿中有以下代码：

import { of } from "rxjs";
import { map } from 'rxjs/operators';

class Main {
  public process() {
    console.log("Hello world!!!");
    of(1, 2, 3).pipe(map(x => x * 2));
  }
}

let main: Main = new Main(); main.process();

当我跑步时

node main.ts

我收到：

main.ts:1
import { of } from "rxjs";
       ^

Answer 1

如果你想运行 rxjs，你需要在 package.json 中输入 type="module"
