正如标题所述，我创建了一个新的数据科学VM（Ubuntu），即使仅使用默认的jupyter hub扩展，运行jupyter build也失败。
在尝试此操作之前，我仅安装了两个其他软件包：Azure存储和pyarrow，用于读取Parquet文件。这些都不应该影响到jupyter。
该配置是Standard B4ms实例，但是我尝试了另一种配置，但它存在相同的问题。
环境是默认的py35 conda env。 Jupyter未安装在根环境中。
更新Jupyter或Jupyter Lab或ipython没有帮助。
这是完整的输出：

我有同样的问题。我通过将jupyterhub版本从0.34.9更新到3.5来解决了这个问题：
conda install jupyterlab=0.35 "ipywidgets>=7.2"
我通过以下链接遵循了说明：JupyterLab Support (Python 3.5+)
希望它能起作用！
