正如标题所说，我创建了一个新的数据Science VM（Ubuntu），即使只使用默认的jupyter hub扩展，运行jupyter build也会失败。
在尝试此操作之前，我只安装了另外两个软件包：Azure存储和用于读取Parquet文件的pyarrow。这些都不应该影响jupyter。
配置是标准B4ms实例，但我尝试了另一种配置，它有同样的问题。
环境是默认的py35 conda env。 Jupyter没有安装在root环境中。 更新Jupyter或jupyter实验室或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来修复它：
conda install jupyterlab=0.35 "ipywidgets>=7.2"
我使用以下链接进行了解释：JupyterLab Support (Python 3.5+)
希望它有效！
我和你的同一天有类似的问题。你的vega-lite 3.0.0-rc14？如果是这样，请尝试使用3.0.0-rc13并构建：
首先通过nam安装rc13：
sudo npm install --prefix /usr/share/jupyter/lab/staging [email protected]
然后更改目录并构建：
cd /usr/share/jupyter/lab/staging
sudo node /usr/lib/python3.4/site-packages/jupyterlab/staging/yarn.js run build:prod
以上解决了我的问题。
