Answer №1

Through persistent effort, I was able to find a solution using the following command:

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

Remarkably, this command proved successful.

In case it fails, you can attempt downgrading the app-script dependency in package.json as shown below:

Initially written as:

"@ionic/app-scripts": "3.2.4"

Change it to:

"@ionic/app-scripts": "3.2.3"

I trust that this information will be of some assistance to others.

Answer №2

In order to resolve the issue, please remove the complete node_modules directory from your project and execute the following command:

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

After implementing this solution, your project should function properly.

Answer №3

Encountering a similar issue (with node v10.3.0 and ionic 3.13.0). This solution worked for me:

Remove package-lock.json file,

Erase the node_modules directory,

Execute npm install once more.

Answer №4

Several files have been either deleted or concealed.

Answer №5

I encountered a problem which was caused by the most recent app-scripts version. To resolve it, I decided to downgrade my app-scripts version by modifying

"@ionic/app-scripts": "3.2.4"

in my package.json file to

"@ionic/app-scripts": "3.2.3"

After making this change, I ran the following command to complete the process:

npm install
