Ionic Native

I initially had cordova 8.0.0. when trying to run ionic cordova run android I faced the following issue.

Ionic build fails with Error: Cannot find module ‘…/cordova/platform_metadata’

I followed this thread Ionic build fails with Error: Cannot find module '../cordova/platform_metadata' and downgraded to 7.1.0

Now am facing different issue as follows

TypeError: Class extends value undefined is not a constructor or null

Can somebody help me how to resolve this?

What is your ionic info output?

The following one… I installed cordova globally but it doesn’t show up

cli packages: (C:\Users\my_user\node_modules)

@ionic/cli-utils  : 1.19.2
ionic (Ionic CLI) : 3.20.0

System:

Node : v7.4.0
npm  : 5.6.0
OS   : Windows 7

Misc:

backend : legacy

You have to run the command in your project directory.

Here is the ionic info output from my project directory

cli packages: (D:\sample\ionic\project_name\node_modules)

@ionic/cli-utils  : 1.10.2
ionic (Ionic CLI) : 3.10.3

global packages:

Cordova CLI : 8.0.0

local packages:

@ionic/app-scripts : 2.1.4
Cordova Platforms  : android 6.2.3 ios 4.4.0
Ionic Framework    : ionic-angular 3.6.1

System:

Node : v7.4.0
npm  : 5.6.0
OS   : Windows 7

Your app scripts version is too old. Try updating it.

Your Cordova tooling seems to be out of date, which might be causing all kinds of problems.
