Anaconda / Jupyter Labs应用程序启动错误

如何解决Anaconda / Jupyter Labs应用程序启动错误

当尝试从anaconda界面启动Jupyter实验室时，我收到以下消息和Jupyter：

const a = [1,2,3,4,5];

const result = [...a.reduce((freqs,item) => freqs.set(item,(freqs.get(item) || 0) + 1),new Map).entries()]
  .sort(([,a],[,b]) => b - a)
  .flatMap(([value,length]) => Array.from({length}).fill(value))

console.log(JSON.stringify(result))

它还会返回另一个错误

Traceback (most recent call last):

ImportError: cannot import name 'secure_write' from 'jupyter_core.paths' (/Users/anaconda3/lib/python3.7/site-packages/jupyter_core/paths.py)

有人知道如何解决此问题吗？
