Heroku Deploy error: 'sh: Syntax error: EOF in backquote substitution' and undefined local variable or method `install_language_pack_gems'
deployment, heroku
Solution
This is Heroku's fault. Perhaps just some caching issue, but maybe they just broke something. Anyway, the solution is to set the `BUILDPACK_URL` for your app to point to the latest Ruby Heroku buildpack:
` heroku config:set BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-ruby -a <app-name> `
Problem
Heroku Deploy for Rails app is failing currently. I am getting the following error message. I haven't changed any gems or rails code but just changed some static HTML and CSS files. ``` -----> Ruby app detected -----> Compiling Ruby/Rails -----> Using Ruby version: ruby-2.0.0 -----> Installing dependencies using 1.5.2 Ruby version change detected.
