Try to follow these steps.
in your project directory run these commands:

rm -rf node_modules

ionic build android

ionic run android


Thanks for the reply. rm -rf node_modules is not working,

'rm' is not recognized as an internal or external command,
operable program or batch file.

which OS are you using?

If you are using windows then this may work:
del node_modules

or you can go to directly into your project directory and just delete the node_modules directory.

After that try to run these commands:
ionic build android
ionic run android

I am using windows.
del node_modules worked
but getting same error on ionic build android

after del node_modules

try npm install

and after that ionic build android

npm install worked. Same error on ionic build android

Try this may help cmd - 'ionic' is not recognized as an internal or external command - Stack Overflow

compare your tsconfig.json file with the following and then use ionic build command

OR try this too


$ ionic platform remove ios or ionic platform remove android
$ ionic hooks add
$ ionic platform ios or ionic platform android

Did you managed to fix that?? I have the same issue. tried install ionic and cordova after unistall and it still not working

No, Didn’t managed to fix this. Will work on the same later, currently working on mac for both (ios and android). Please let me know if you fix this.

Wasn’t working on this topic since one month. Worked yesterday and solved.

Run below commands step wise in your project:

  1. npm install @ionic/app-scripts@latest
  2. npm rebuild node-sass
  3. ionic platform remove android
  4. ionic platform add android

Now try to run ionic run android. It should work (worked for me).
