I am trying to run jupyterhub for multiuser mode:

sudo jupyterhub

I am able to login successfully with the user I used to install jupyterhub. However, when I try to login with other users I get the following message:

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

And in the terminal:

user@server:~$ sudo jupyterhub

I don't know if that would be the source of the problem, however, I have jupyterhub version: 0.7.0. I tried to update it to 0.8.0 using: 

sudo pip install -U jupyterhub

But, I got:

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

I tried so long to find a solution online; I failed though.

Would someone please help me with this issue?

Thanks :)

你可能会从源代码安装 jupyterhub 并看到这个日志：</p>

“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......这是由安装二进制 jupyterhub 并且不安装包引起的......在 exec 之后

pip3 install -r dev-requiremetns.txt .

日志让我们通过“为jupyterhub运行setup.py开发”来执行setup.py，然后运行python setup.py build然后python setup.py install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 .
