heroku上的therubyracer错误为“无法通过Bundler安装宝石”。

Question

当我把我的应用程序的Heroku它给了我下面的错误

-----> Ruby/Rails app detected 
-----> Installing dependencies using Bundler version 1.3.2 
     Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin --deployment 
     You are trying to install in deployment mode after changing 
     your Gemfile. Run `bundle install` elsewhere and add the 
     updated Gemfile.lock to version control. 
     You have added to the Gemfile: 
     * therubyracer 
! 
!  Failed to install gems via Bundler. 
! 
!  Heroku push rejected, failed to compile Ruby/Rails app 

我删除了我Gemlock文件并重新捆绑安装，但仍然给了我同样的错误。我也试过bundle install --without development:test生产它也给我同样的错误我能做什么。这里是我的Gemfile

source 'https://rubygems.org' 

gem 'rails', '3.2.9' 

gem 'carrierwave' 
gem 'newrelic_rpm' 

#gem "less-rails" #Sprockets (what Rails 3.1 uses for its asset pipeline) supports LESS 

#gem "twitter-bootstrap-rails" 
gem 'will_paginate', '3.0.3' 
#gem 'bootstrap-will_paginate', '0.0.6' 
# Bundle edge Rails instead: 
# gem 'rails', :git => 'git://github.com/rails/rails.git' 

#gem 'mysql2' 
gem 'dynamic_form' 
gem 'therubyracer', '0.10.2', :platforms => :ruby 
gem 'devise' 
gem 'hirb' 

# Gems used for Facebook

gem 'thin' 
gem 'pg' 
# Gems used only for assets and not required

    gem 'uglifier', '>= 1.0.3' 
end 

gem 'jquery-rails' 

Answer 1

尝试运行bundle install比推送更改为远程回购。

此外，如果你使用therubyracer资产编译，你可以在本地预编译的资产和阅读文档：从 https://devcenter.heroku.com/articles/rails-asset-pipeline#compiling-assets-locally https://devcenter.heroku.com/articles/rails-asset-pipeline#therubyracer

Answer 2

therubyracer宝石是用来评估JavaScript内Ruby（它嵌入JavaScript解释为红宝石） 。

这个宝石是必需的，如果你是在Ubuntu中开发的，ubuntu没有Javascript runtime。

但是它没有与Heroku的情况。

所以，只要保持线为Gemfile下development组therubyracer宝石如下所示：

group :development do 
    gem 'therubyracer', '0.10.2', :platforms => :ruby 
end 

Answer 3

根据Heroku docs：

如果您以前使用therubyracer或therubyracer-的Heroku ，这些宝石不再需要，并且强烈不鼓励，因为这些宝石使用了大量的内存。

由于在Ubuntu的替代，您可以安装的NodeJS：

sudo apt-get install nodejs
