Jupyterhub无法启动服务器-500错误 [英] Jupyterhub cannot start server - 500 error

问题描述

我正在尝试为多用户模式运行jupyter hub.我从PIP安装了jupyterhub.

I am trying to run jupyter hub for multiuser mode. I installed jupyterhub from PIP.

[root @ ip-of-machine hadoop]#echo $ PATH

[root@ip-of-machine hadoop]# echo $PATH

/usr/local/bin/jupyterhub-singleuser:/usr/local/bin/jupyterhub:/sbin:/bin:/usr/sbin:/usr/bin:/opt/aws/bin

/usr/local/bin/jupyterhub-singleuser:/usr/local/bin/jupyterhub:/sbin:/bin:/usr/sbin:/usr/bin:/opt/aws/bin

当我调整jupyterhub时​​，我收到一条错误消息

When I tun jupyterhub I get an error saying

500:内部服务器错误

500 : Internal Server Error

无法启动服务器.请联系管理员.

Failed to start your server. Please contact admin.

我以

[root@ip-of-machine hadoop]# /usr/local/bin/jupyterhub -f ./jupyterhub/jupyterhub_config.py --no-ssl

日志包含

[I 2016-05-03 17:13:09.406 JupyterHub spawner:465] Spawning jupyterhub-singleuser --user=jupyter --port=40770 --cookie-name=jupyter-hub-token-jupyter --base-url=/user/jupyter --hub-host= --hub-prefix=/hub/ --hub-api-url=http://127.0.0.1:8081/hub/api --ip=127.0.0.1

但是路径中有单用户.我将其显式添加到path并导出.

But there is singleuser in path. I explicitly added it to path and exported.

有任何线索吗?谢谢.

推荐答案

PATH应该包含目录的列表，其中包含应该找到的可执行文件，而不是可执行文件本身.

PATH should contain a list of directories containing executables that should be found, not the executables themselves.

所以不是

/usr/local/bin/jupyterhub-singleuser:/usr/local/bin/jupyterhub:/sbin:/bin:/usr/sbin:/usr/bin:/opt/aws/bin

您的路径应为:

/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/opt/aws/bin

应该同时找到jupyterhub和jupyterhub-singleuser.
