Guys i solved this issue. Just want to share with you to save your time at least. Follow steps.

  1. Remove node_modules.
  2. Downgrade Node to version 6 (run npm install node@6 or brew install node@6)
  3. Add "@ionic/app-scripts": "3.1.9" under dependencies in project.json
  4. npm i

Remove "@ionic/app-scripts": "2.1.4" from your package.json file firstly.

According to your ionic info, you have a problem with app-scripts.So you can install latest as shown below.

and after that compile: 

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

Remove "@ionic/app-scripts": "2.1.4" from your package.json file firstly.

Update from Git

Running on Windows you might try:

  1. Set environment in local command window and verify problem:

    set OPENSSL_CONF=c:\dummy
    npm -v

=> you now probably see this ssl error message

  1. Remove environment and verify problem is gone:

    set OPENSSL_CONF=npm -v

=> no ssl error message

Run:

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

to install app-script.

Then:

npm install

To install node_modules to avoid Typescript error

And it worked for me.

I had the same error. I tried update npm , reinstall app-script. I uninstalled node and npm, and then installed again and work it. I think that error was because the version of npm instaltion was diferent to the original instalation of node
