Not working on cedar-14 stack

[joelmahoney]

I attempted to upgrade a couple of projects to the cedar-14 stack and got an rgeo build error. Works fine on cedar-10. Here's the deploy error:

I was able to resolve this issue by running heroku repo:purge_cache before heroku stack:set cedar-14 and then deploying. After doing so, RGeo::Geos.supported? returned true, unlike @beejamin's report in #23

[desaperados]

I've got exactly the same issue with the same output as above on cedar-14. I'm also able resolve by running heroku repo purge:cache which results in a successful build with RGeo::Geos.supported? => true

However, the next time I deploy I'm back to the same error. So basically not able to deploy without first running heroku repo purge:cache.

Ran into something quite similar. Here's how we solved it:

1. Put the geos buildpack before the ruby buildpack
2. Run heroku repo:purge_cache (see: https://github.com/heroku/heroku-repo)
3. Push to heroku (you may have to git commit --allow-empty)

Basically gems get cached between deploys, even if you add a new buildpack. So you need to clear out the gem cache, then redeploy to rebuild gems. Output should look like...

$> git push heroku

... [misc gem install stuff] ...

The important part here is that installing the geo buildpack comes before bundle install.

After that I get...

$> heroku run rails c
irb> require 'rgeo'
=> false
irb> RGeo::Geos.supported?
=> true
irb> RGeo::CoordSys::Proj4.supported?
=> true

Hope this helps someone!
