Ionic starter and plugin error

Hello,
I’m using ionic since about 6 months, now I have problems with the starter and plugins. When I use the starter there are this errors:

PS C:> ionic start Demo blank
√ Creating directory .\Demo - done!
√ Downloading and extracting blank starter - done!

? Would you like to integrate your new app with Cordova to target native iOS and Android? Yes
√ Personalizing ionic.config.json and package.json - done!

ionic integrations enable cordova --quiet
[ERROR] Error with .\emo\node_modules\ionic-angular\package.json file: FILE_NOT_FOUND
[ERROR] Error with .\emo\node_modules@ionic\app-scripts\package.json file: FILE_NOT_FOUND
√ Downloading integration cordova - done!
√ Copying integrations files to project - done!
[OK] Added cordova integration!

Installing dependencies may take several minutes.

  • IONIC DEVAPP *

Speed up development with the Ionic DevApp, our fast, on-device testing mobile app

  • Test on iOS and Android without Native SDKs
    
  • LiveReload for instant style and JS updates
    

️–> Install DevApp: Ionic DevApp - Appflow

npm i

the path in the error is every time truncate.
When I install the plugins there are many dependency warning and during debug the plugin is not installed.

What am I doing wrong?

Thank you
