可能遇到的问题

无法卸载扩展

如果使用

1	jupyter labextension list

出现

installed 和 uninstalled 相同的条目，可以移除 build_config.json 来解决。

无法安装扩展

因为build jupyterlab 扩展时，需要使用 npm 安装一些插件，所以 npm 按照插件成功与否会直接影响 jupyterlab 扩展 build 的成败。下面介绍如何安装 npm 和配置国内源

sudo apt update 
sudo apt install nodejs
# 配置淘宝源
npm config set registry https://registry.npm.taobao.org
# 或者使用工具 nrm 管理源，首先安装 nrm
npm install -g nrm
# 查看可用源
nrm ls
# 切换国内源
nrm use taobao
