【中文标题】登录 jupyterhub 时，报告 500 : Internal Server Error

【英文标题】：when log in jupyterhub ,report 500 : Internal Server Error

【发布时间】：2022-01-07 21:22:12

【问题描述】：

我从源代码安装 jupyterhub，版本是 0.9.4。我尝试使用 root 用户登录，但服务器响应 500 消息。

500 : 内部服务器错误 Spawner 无法启动 [status=1]。 root 的日志可能包含详细信息。 您可以尝试从主页重启服务器。

然后我点击主页并启动我的服务器，它失败并显示消息：

生成失败：http://192.168.183.148:47297/user/root/ 的服务器在 30 秒内没有响应

我的 jupyterhub_config.py

c.JupyterHub.authenticator_class = 'dummyauthenticator.DummyAuthenticator'
c.JupyterHub.bind_url = 'http://192.168.183.148:8000'
c.JupyterHub.data_files_path = '/usr/local/share/jupyterhub'
c.Spawner.ip = '192.168.183.148'
c.Authenticator.admin_users = 'root'
c.Authenticator.whitelist = 'root','vinwin'
c.PAMAuthenticator.encoding = 'utf8'

[root@localhost jupyter]# jupyterhub -f jupyterhub_config.py

我在 ubuntu 和 centos 有同样的错误。 他们都安装了python3和python2。

【问题讨论】：

我尝试了两种安装jupyterhub的方法：python3 -m pip install jupyterhub-0.9.4.tar.gz和python3 setup.py build && python3 setup.py install && python3 -m pip install .

你有 IP 192.168.183.148 吗？也许使用127.0.0.01 或0.0.0.0

欢迎堆栈溢出。感谢您发布完整的堆栈跟踪 - 非常有帮助！

我将其部署在 vmware 而不是 localhost。

【参考方案1】：

查看这个 github 问题：https://github.com/jupyter/notebook/issues/6100

最近发布的 jupyter_client 与 python ≤ 3.5 不兼容。您需要使用更新版本的 python 或将 jupyter_client 固定到 6.1.12 或更早版本。

【讨论】：

"/usr/local/lib/python3.5/site-packages/jupyter_client/channels.py" 引发了错误，所以您使用的是 python 3.5 - 可能在 docker 容器内？

谢谢，但是没用，我试过python3.9.7和notebook 5.0.0，python 3.5.0和notebook 5.6.0。

我部署在vmware，centos和ubuntu都试过了。
