我认为jupyterhub是官方网站，
c.JupyterHub.hub_ip = '0.0.0.0'
c.JupyterHub.hub_port = 8888
c.PAMAuthenticator.encoding = 'utf8'
c.LocalAuthenticator.create_system_users = True
c.Authenticator.admin_users = {'arvin'}
c.Spawner.cmd=['jupyterhub-singleuser']
c.JupyterHub.ssl_cert = '/mycert'
c.JupyterHub.ssl_key = '/mykey'
当我进入用户页面（登录）时，我得到了这个：
500 : Internal Server Error
Failed to reach your server. Please try again later. Contact admin if the issue persists.
You can try restarting your server from the home page.
有人能给我一些解决方案吗？ 我尝试了一些，但他们似乎没有按摩。
这些是我的日志。

我注意到有些问题可能无法达到产卵者但我真的不知道该做什么，即使我已阅读官方文档。
答案 0 :(得分：1)
如果您在集线器安装之前使用了笔记本，并且存在〜/ .jupyter /文件夹。当您启动集线器程序并启动单用户笔记本时，它会读取那里的配置并导致一些问题，以便集线器永远不会到达单个spawner，直到超时。
我认为这是一个与笔记本配置〜/ .jupyter冲突的BUG。
只要您将$ HOME / .jupyter移开，一切都会正常。
