无法在 GCP AI Platform Notebooks 上安装 Jupyterlab 扩展

问题描述

我在为 Jupyterlab 安装扩展时开始遇到我过去没有遇到过的问题。为 Jupyterlab 安装新扩展后，我无法构建。

我正在使用 GCP AI Platform Notebooks 运行 Jupyterlab。我在 Debian 10 上使用标准 Python 3 环境。我尝试在不同类型的机器上运行。

我收到状态 500 错误。这是我运行 jupyter lab build 时的日志：

[LabBuildApp] WARNING | Config option `kernel_spec_manager_class` not recognized by `LabBuildApp`.
[LabBuildApp] JupyterLab 1.2.16

An error occured.

这是包含详细信息的日志文件：

由于我过去能够在其他 VM 实例上为 Jupyterlab 安装相同的扩展，因此我希望它与安装的 Jupyterlab 版本有关。但是，我希望 Google 安装最新版本的 Jupyterlab。

错误日志似乎表明这是一个权限错误，我不明白，因为我在基础上运行 jupyter lab build。创建实例后我更改的唯一设置是启用扩展。

解决方法

您需要以 root 身份编译 jupyter-lab。它不太直观，因为 jupyter 不包含在 root 用户的 $PATH 中。

这是要做的：

sudo apt-get install nodejs  # needed to compile jupyter-lab
sudo /opt/conda/bin/jupyter lab build

gcp-ai-platform-notebook jupyter-lab python
