Question

我在控制台中尝试执行jupyter-notebook时遇到错误，错误发生在这里：

devnull = open(os.devnull, 'w')
    FileNotFoundError: [Errno 2] No such file or directory: 'nul'

奇怪的是它开始发生在一天到另一天，因为直到最近我才能完美地使用jupyter-notebook，因为我卸载了这个错误，然后重新安装了anaconda，但错误仍然存在。

我的操作系统是Windows 10，我安装了64-bit installer with python 3.6

Traceback是：

C:\Users\username\Anaconda3\Scripts>jupyter notebook
