能不能够启动jupyter

Question

当我尝试jupyter运行它给我的错误： -

ERROR: the notebook server could not be started because no available port could be found.

终端登录如下： -

[I 20:52:08.747 NotebookApp] The port 8888 is already in use, trying another random port. 
[I 20:52:08.748 NotebookApp] The port 8889 is already in use, trying another random port. 
[I 20:52:08.748 NotebookApp] The port 8890 is already in use, trying another random port. 
[I 20:52:08.749 NotebookApp] The port 8891 is already in use, trying another random port. 
[I 20:52:08.750 NotebookApp] The port 8892 is already in use, trying another random port. 
[I 20:52:08.750 NotebookApp] The port 8988 is already in use, trying another random port. 
[C 20:52:08.779 NotebookApp] ERROR: the notebook server could not be started because no available port could be found. 

而且，我也检查了我系统来检查哪个进程正在该端口上运行，我发现没有进程正在运行，并且所有这些端口都没有被任何进程使用。但是，仍然有这个错误。

我也改变jupyter其他各种端口的默认端口，但仍然得到同样的错误。

错误可能不是由jupyter引起的，而是您的系统。

要清除此问题，您可以尝试在端口8888上打开一个简单的http服务器，并查看失败的消息是否相同。

你可以试试下面的命令之一启动HTTP服务器：

python -m SimpleHTTPServer 8888 (Python2) 
python -m http.server 8888 (Python3)
