Ionic-app-scripts: 1.2.2 "ionic serve" just hangs and not responding

[anton-white]

Ionic 2
app-scripts 1.2.2

After I updated ionic-app-scripts from 1.1.4 to the latest 1.2.2, ionic serve just hangs without any error message.

I tried setting up a new project with ionic start testIonic --v2 and experienced the same behavior.

@anton-white,

That seems strange to me. How can I recreate it?

Thanks,
Dan

1. ionic start testIonic --v2
2. cd testIonic
3. ionic serve

I can confirm the behavior, just hangs after ionic serve. (Ubuntu)

Me too on Ubuntu 16.04 desktop

I have downgraded the version of app-scripts to 1.1.4 with npm install @ionic/[email protected] --save-dev. Now it works

Man, that's cool :)
but if you look closer at my initial message:

After I updated ionic-app-scripts from 1.1.4 to the latest 1.2.2

This is the issue right now, there are few issues open at ionic-cli repo, the fix so far is to downgrade it back to 1.1.4 as suggested by @pawelkat. However, I think we are looking for the long term fix, which is fix in the latest script rather than downgrade.

@danbucholtz In order to recreate it, you just need to start a new project like before, and then navigate to the project folder and run the serve command

$ ionic start ionic2-blank blank --v2
$ cd ionic2-blank
$ ionic serve

Are you all on linux? There is a known issue fixed in nightly for linux.

Thanks,

@danbucholtz no, windows 7
@ionic/[email protected] up all versions not working,
1.1.4 works

Hi there,
I was having the same issue as described above but with "npm run build", which was hanging on my Linux environment but working fine on macOS. In case somebody has the same issue, I can confirm that upgrading to the nightly build (1.2.2-201703281515 as of today) fixed the issue on Linux.

[danbucholtz]

This should be working now with 1.2.3. Can you please let me know if it's not and I'll re-open.

Thanks,
Dan

[anton-white]

@danbucholtz,
it's working now. Thanks a lot!
