Failed to detect set buildpack

[igorrKurr]

Hi! I have problem with using this buildpack. It seems like heroku can't fetch ot for some reason. Here what i did:

>>heroku buildpacks:set https://github.com/tonycoco/heroku-buildpack-ember-cli                                   ⏎
Buildpack set. Next release on pacific-brook-4652 will use https://github.com/tonycoco/heroku-buildpack-ember-cli.
Run git push heroku master to create a new release using this buildpack.

>>git push heroku master

My heroku toolbelt version command shows next:

usually running heroku repo:purge_cache -a APPNAME fixes this issue. doesn't seem to help today

[lucascampbell]

working now.

I have the same error. heroku repo:purge_cache -a APPNAME fails with

...
~/tmp/repo_tmp $ cd unpack
~/tmp/repo_tmp/unpack $ tar -zxf ../repo-cache.tgz

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

Any idea?

[tonycoco]

Could you paste the entire output log? Have you set heroku buildpacks:set https://github.com/tonycoco/heroku-buildpack-ember-cli? And have you then run heroku repo:purge_cache -a APPNAME

[dahoo]

Yes, here's what I did:

I'll have to try to reproduce this

[dahoo]

It works now for some reason...
