jupyter-notebook - 干净地卸载损坏的 jupyter nbextension

问题描述

前段时间我安装beakerx了一个更新，安装失败了。每次我启动 IPython 时，都会显示一个警告。我怎样才能干净地摆脱扩展和这个输出？

解决方案

遵循卸载说明后，我grep -r beakerx *在 virtualenv 的根目录中运行并发现了以下碎片：

etc/jupyter/jupyter_notebook_config.json:      "beakerx": false
etc/ipython/ipython_config.py:c.InteractiveShellApp.extensions = ['beakerx.autotranslation',
etc/ipython/ipython_config.py:'beakerx_magics.kernel_magic',
etc/ipython/ipython_config.py:'beakerx_magics.groovy_magic',
etc/ipython/ipython_config.py:'beakerx_magics.clojure_magic',
etc/ipython/ipython_config.py:'beakerx_magics.kotlin_magic',
etc/ipython/ipython_config.py:'beakerx_magics.scala_magic',
etc/ipython/ipython_config.py:'beakerx_magics.sql_magic',
etc/ipython/ipython_config.py:'beakerx_magics.java_magic'

我从上述文件中删除了违规行，错误消息消失了。

为了ipython_config.py

c = get_config()
c.InteractiveShellApp.extensions = [
]

为了jupyter_notebook_config.json

{
  "NotebookApp": {
    "nbserver_extensions": {
    }
  },
  "KernelSpecManager": {}
}
