Question

我已经在Windows 10上安装了Anaconda，每次打开Jupyter Notebook时，都会出现以下错误。有人可以帮助您了解问题的解决方案吗？

 import { map } from 'rxjs/operators';
 import { interval } from 'rxjs';
 import { JwtHelperService } from '@auth0/angular-jwt';

 ...

 public validateToken(): void {
    interval(1000).pipe(
      map(() => {
        const isExpired: boolean = this.jwtHelper.isTokenExpired(
          localStorage.getItem('jwt_token'),
        );
        if (isExpired) {
          this.logout();
        }
      }),
    );
  }

jupyter kernelspec列表的输出：jupyter kernelspec列表

我已经在以下文件夹中创建了一个新文件，该文件位于（C：\ Users \ myusername.ipython \ kernels \ pyspark2.2）下，该文件夹用于安装Apache Spark，它将在Jupyter Notebook上启用Pixiedust，但同时不起作用。

引用了以下链接来创建以下kernels.json文件：https://github.com/pixiedust/pixiedust/wiki/Setup:-Install-and-Configure-pixiedust
