• For general technical questions, post a question on StackOverflow tagged with errbit.

Step 2: Describe your environment

• Errbit version: master, right now the latest commit is e00a3ba
• OS: heroku stack

Step 3: Describe the problem:

I do everything like the the heroku deployment doc, with a minimal change ( use ruby 2.5.8 instead of 2.5.1 as the tutorial since Heroku force us to use the latest version), then I get the following error while bundle install

An error occurred while installing libv8 (8.4.255.0), and Bundler cannot
       continue.
       Make sure that `gem install libv8 -v '8.4.255.0' --source
       'https://rubygems.org/'` succeeds before bundling.
       
       In Gemfile:
         mini_racer was resolved to 0.3.1, which depends on
           libv8
 !
 !     Failed to install gems via Bundler.
 !
 !     Push rejected, failed to compile Ruby app.
 !     Push failed

Steps to reproduce:

1. Do everything like tutorial
2. Use version 2.5.8

Expected Results:

• bundle install should not raise any error

Hey there, Errbit has some unresolved issues with libv8 and Heroku in combination with current Bundler. This is probably related to #1494

I googled again as this must be a common issue and I found this note about therubyracer so my conclusion is... just don't have mini_racer on Heroku?

I have no idea about Heroku and can't try it (because I'm a german potato with no credit card to verify) but maybe you or someone else can give it a try.

Just be aware that Errbit currently won't run on Ruby 2.7 (until #1508 is resolved) but it should run just fine on 2.6 (or 2.5 for that matter)
