Ionic3项目添加平台/插件失败：Cordova不识别add命令求助

Alright, let's get this sorted out. The error you're hitting is a straightforward command syntax mistake—here's how to fix it step by step:

The error message Cordova does not know add tells us exactly what's wrong: you're using an invalid Cordova command structure. cordova add platform isn't a valid command—Cordova expects you to specify the target (like platform or plugin) first, followed by the action (like add).

1. Correct the Platform Add Command #

Replace your incorrect command:

cordova add platform

With the proper syntax (using Android as an example; swap with ios if needed):

# Pure Cordova command
cordova platform add android
# Or use the Ionic-wrapped command (better for Ionic 3 projects)
ionic cordova platform add android

2. Validate the Plugin Install Command #

Your plugin install command syntax is actually correct, but if you still run into issues after fixing the platform command, try re-running it after ensuring your Cordova environment is stable:

ionic cordova plugin add https://github.com/moust/cordova-plugin-videoplayer.git

3. Extra Troubleshooting (If Issues Persist) #

• Check your Cordova version to ensure it's compatible with Ionic 3 (Ionic 3 works best with Cordova 8.x to 9.x):

  cordova -v
  

• Clear Cordova's cache to eliminate any cached corruption:

  cordova clean
  

• If all else fails, reset your platforms and plugins folders (they can sometimes get corrupted):

  # Delete the problematic folders
  rm -rf platforms plugins
  # Re-add your platform and plugin
  ionic cordova platform add android
  ionic cordova plugin add https://github.com/moust/cordova-plugin-videoplayer.git
