Can not uninstall plugin

I’m currently trying to make a custom plugin based on https://www.youtube.com/watch?v=QSZ1sewo0nA

but when I try to uninstall my plugin (appium plugin uninstall appium_plugin) I have the following message
‘Cannot uninstall plugin “appium_plugin” because it is in development!’

extra info:
when I run ‘appium plugin list’
I have the output
:heavy_check_mark: Listing available plugins

  • [email protected] [installed (dev mode)]
  • images [not installed]
  • execute-driver [not installed]
  • relaxed-caps [not installed]
  • universal-xml [not installed]

My question is: what to do to be able to uninstall my plugin?
