Ionic serve & build both stops mid way before building the app

Zahema · September 5, 2017, 6:02pm

If I run ionic serve I get:

[INFO] Starting app-scripts server: --address 0.0.0.0 --port 8100 --livereload-port 35729 - Ctrl+C to cancel
[19:56:35]  watch started ...

Then nothing, no files created no localhost started, nothing, it just stops.

This started out of no where while I was working today. The localhost stopped working and the serve or build command wont work.
I tried updating everything, uninstalling and reinstalling everything, nothing helped.
My other projects works normally.
www/build only contains polyfills.js & sw-toolbox.js

Here is my ionic info

cli packages: (E:\Ionic\workspace\mb\node_modules)

    @ionic/cli-utils  : 1.9.2
    ionic (Ionic CLI) : 3.9.2

Run the same command with --verbose for more output.
Run npm run ionic:build --verbose for an another angle.

I am guessing this is the error: Cannot read property 'substr' of undefined ?

I found the problem, one of my components had 2 .html files. It kinda was like 2 components in 1 so it had like a template and a child template. Removing the child template html file fixed the problem -I included the html in the .ts file instead.
This is a really weird problem. I know my structure does not really follow the standard but one would never guess it wont work, specially when there is no error message.
Thank you for your help.

Sujan12 · September 5, 2017, 6:27pm

Yes, but not idea what it means.

Do you get this also with a new project created with ionic start blank blank?

Sujan12 · September 5, 2017, 6:28pm

You might want to create a Github issue for app-scripts and describe this problem. This should maybe be cought or at least output in a better way.

Zahema · September 6, 2017, 9:00am

No. As I said in the post my other projects worked normally.

Zahema · September 6, 2017, 9:01am

I am not very knowledgeable on how to do that, but I will try ^^

Sujan12 · September 6, 2017, 9:35am

Just go here and add the information you descirbed above: https://github.com/ionic-team/ionic-app-scripts/issues/new
