使用 docker 设置 Jupyterhub - TraitError

我正在尝试在 docker 上设置 jupyterlab。

我的解决方案基于https://opendreamkit.org/2018/10/17/jupyterhub-docker/主要的例外是使用本地 Linux 用户帐户授权。

登录后出现以下错误：

有没有什么办法可以修复或者解决这个问题？

看起来问题出在网络名称上，因为引用的链接中提出的网络名称不是默认的。

它还要求在重建之前删除所有容器（至少在docker-compose中指定）

更改的文件：

.环境：

COMPOSE_PROJECT_NAME=myhub

docker-compose.yml：

version: '2'
