Hi,

Getting a build failure when trying to build an ionic2 app for android.

[11:15:16]  copy started ...
[11:15:16]  ngc started ...
[11:15:17]  copy finished in 286 ms

Hi I had the same problem a few days back.
I’ve tried a few changes and it worked finally but I’m not sure which solved the problems.

I guess it happened after updating ionic-cli.
If so, you can try upgrading to the latest ionic-app-scripts also. You need to do some changes on the config files.

Another thing I did is simply removing all the caret symbols in package.json
I don’t know if this could help, but I read this somewhere.

Do you have any object with a property “text” in a view?

I had the same error during ngc.
It was due to upgrading typescript from 2.0.6 to the latest 2.1.4.
Since downgrading back to 2.0.6 it builds fine.

I had the same error.

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

after

has own your app /src/app/main.ts

main.dev.ts and main.prod.ts are depreciated

my package.json
"devDependencies": {
"@ionic/app-scripts": “^1.0.0”,
“typescript”: “2.1.4”
},
