I installed heroku-buildpack-php-tyler on my Heroku app a few days ago, and it all seemed to work fine. I installed it by running the following command:

heroku config:set BUILDPACK_URL=git://github.com/iphoting/heroku-buildpack-php-tyler.git

However I now want to remove it. I tried using the following command:

heroku config:unset BUILDPACK_URL=git://github.com/iphoting/heroku-buildpack-php-tyler.git

But it returns the following error message:

Unsetting BUILDPACK_URL=git://github.com/iphoting/heroku-buildpack-php-tyler.git and restarting hnf-heroku... failed

! Resource not found`

Because PHP isn't officially supported by Heroku, there's not much documentation about this. So how do I uninstall this buildpack?

In the current version of heroku (v3.1.0 as of this writing) you can use heroku buildpacks:remove [BUILDPACK_URL]

Typing heroku buildpacks help lists the available commands: 

  buildpacks:add BUILDPACK_URL       #  add new app buildpack, inserting into list of buildpacks if neccessary
  buildpacks:clear                   #  clear all buildpacks set on the app
  buildpacks:remove [BUILDPACK_URL]  #  remove a buildpack set on the app
  buildpacks:set BUILDPACK_URL       #  set new app buildpack, overwriting into list of buildpacks if neccessary

Try:

heroku config:unset BUILDPACK_URL

  • hey thanks, I already got the answer from somewhere else, but this works (for those coming from Google, it essentially resets the Buildpack back to the default state). Thanks though! :) – Tom Oakley May 04 '14 at 18:54

    `heroku buildpacks:remove BUILDPACK_URL --app [APP_NAME]` is the correct one. – adaam May 16 '18 at 14:17

Running heroku config:unset and heroku buildpacks:remove did not work for me. However, simply running heroku buildpacks:clear did restore everything to its default state. Then, on the next git push heroku, the appropriate buildpack is added on the fly.

  • Your approach may work on some cases but it isn't necessarily true. There are situations that require a little bit of attention in the process of choosing (and even ordering) buildpacks. – Jonathan Soifer Oct 24 '17 at 06:44
