由於libv8而無法Git推送Heroku Master

Question

當我運行git push heroku master時，我得到了這個錯誤，紅寶石賽車安裝得很好，所以libv8我在互聯網上看了很多，還沒有解決這個問題，任何幫助都會很棒，我正在嘗試將本地回購推送到heroku

doom@linux:~/rails_projects/first_app$ git push heroku master

   The Ruby Racer requires libv8 ~> 3.11.8
   to be present on your system in order to compile
   and link, but it could not be found.
   In order to resolve this, you will either need to manually
   install an appropriate libv8 and make sure that this
   build process can find it. If you install it into the
   standard system path, then it should just be picked up
   automatically. Otherwise, you'll have to pass some extra
   flags to the build process as a hint.
   If you don't want to bother with all that, there is a
   rubygem that will do all this for you. You can add
   following line to your Gemfile:
   gem 'libv8', '~> 3.11.8'
   We hope that helps, and we apologize, but now we have
   to push the eject button on this install.
   thanks,
   The Mgmt.
   Gem files will remain installed in /tmp/build_201rmwb3smm2n/vendor/bundle/ruby/1.9.1/gems/therubyracer-0.11.0 for inspection.

所以看來，現在有一個已知的問題，我無法解決

Answer 1

我遇到了同樣的問題，並嘗試了建議之一（使用已知的工作therubyracer ）：

# Gemfile
gem 'therubyracer', '0.10.2', :platforms => :ruby

而已。 我可以再次部署到Heroku。

Answer 2

您不需要包括therubyraceret.al。 還有。

Therubyracer

如果您以前使用過therubyracer或therubyracer-heroku，則不再需要這些寶石，並且強烈建議不要使用這些寶石，因為這些寶石會占用大量內存。
