Ionic Serve throws a Type-Error: Appscripts.serve

Question

I recently cloned a project and when I tried to serve it, I got an error:TypeError: AppScripts.serve is not a function.

How would I go about fixing this issue/where should I look?

I have already tried updating ionic, and reinstalling all plugins(just in case).

Assistance on this would be greatly appreciated !

Answer 1

Running this command works for me

npm install --save-dev @ionic/app-scripts@latest

and then

ionic serve

I face the same issue when i started developing old ionic 2 project with ionic 3. follow the following steps works for me :

npm cache clear

delete the node-modules folder

npm install

npm install --save-dev @ionic/app-scripts@latest

ionic serve

Answer 3

Execute this command:

npm install --save-dev @ionic/app-scripts@latest

After that your app should work using

ionic serve
