关于jupyter突然打不开的问题

好久没有用python了，我的电脑环境是安装过anaconda和pycharm，但是有些简单的东西就希望在jupyter中测试一下，但是最近发现jupyter打不开了。

具体是：

在这里打开jupyter是可以的，但是在命令行就不行，表现为命令行窗口闪退，连错误信息都看不到。

命令行导致窗口闪退，想到的是在命令后加个输出，将输出信息保存到文件中

jupyter-notebook.exe>>lzb.txt

命令>XXX.txt 只是创建或者覆盖XXX.txt文件

命令>>XXX.txt 就是创建或者追加XXX.txt文件

文件中保存的信息为：

_cffi_ext.c

D:\Anaconda3\lib\site-packages\zmq\backend\cffi\pycache\_cffi_ext.c(268): fatal error C1083: 无法打开包括文件: "zmq.h": No such file or directory

奇怪的是，这时命令行窗口竟然停留住了，贱不贱

命令行窗口显示的错误如下

D:\Anaconda3\Scripts>jupyter-notebook.exe>>lzb.txt
