Ubuntu Jupyterhub : 500 POST Spawner failed to start [status=1]

Question

我正在尝试为多用户模式运行 jupyterhub:

sudo jupyterhub

我能够使用我用来安装 jupyterhub 的用户成功登录。但是，当我尝试与其他用户一起登录时，我收到以下消息:

500: Internal Server Error Spawner failed to start [status=1]

在终端:

user@server:~$ sudo jupyterhub

我不知道这是否是问题的根源，但是，我有 jupyterhub 版本:0.7.0。我尝试使用以下方法将其更新为 0.8.0:

sudo pip install -U jupyterhub

但是，我得到了:

Requirement already up-to-date: ****

我尝试了很久才在网上找到解决方案；不过我失败了。

有人可以帮我解决这个问题吗？

谢谢 :)

你可以从源代码安装 jupyterhub 并看到这个日志:

“pkg_resources.DistributionNotFound: 'jupyterhub==0.8.0.dev0' 分发未找到，应用程序需要”

我遇到了同样的问题，并且...这是由安装二进制 jupyterhub 并且不安装软件包引起的...
执行后

pip3 install -r dev-requiremetns.txt .

日志让我们通过“运行 setup.py develop for jupyterhub”来执行 setup.py，然后运行 ​​python setup.py build和 python setup.py install然后中止，日志让我使用pip install .然后运行 ​​pip3 install . ，然后jupyterhub正常运行。

以下命令:

cd /path to git code/jupyterhub/
python setup.py build
python setup.py install
pip3 install .
