Question

我是Ruby的新手，也是通过远程工具部署应用程序的条款。我试图在免费的openshift帐户上部署我的应用程序。我不会运行应用程序。

当我运行应用程序时，我收到此错误：

You have already activated rack 1.5.2, but your Gemfile requires rack 1.6.0.
Using bundle exec may solve this. (Gem::LoadError)

所以我尝试运行bundle exec，但我又遇到了另一个错误：

Gemfile syntax error:
/var/lib/openshift/xxxxxxxxxxxxxxxxxxxxxxxxxx/app-root/runtime/repo/Gemfile:24: 
syntax error, unexpected ':', expecting $end
gem 'sdoc', '~> 0.4.0', group: :doc

我想这可能是因为我在本地使用Ruby 2.1.5，而默认情况下Open open运行Ruby 2.0。

我有这个话题How can I force a bundle install on OpenShift Online when my RAILS_ENV is set to development? 但我不知道我做得对。我甚至不知道把这个pre_build文件放到哪里。我试着把它放在/var/lib/openshift/xxxxxxxxxxxxxxxxxxxxxxxxxx/app-root/runtime/repo/.openshift/action_hooks/下面。但我不确定runtime是否是正确的回购。

编辑1：

这是我的Gemfile：

source 'https://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.0'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '~> 4.1.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
group: :doc do
    gem 'sdoc', '~> 0.4.0'
end

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

# Use Unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug'

  # Access an IRB console on exception pages or by using <%= console %> in views
  gem 'web-console', '~> 2.0'
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :jruby]

SOLUTION：

@Rajarshi Das说我必须改变

gem 'sdoc', '~> 0.4.0', group: :doc

进入

group: :doc do
    gem 'sdoc', '~> 0.4.0'
end

我不知道为什么。可能是一些语法问题，因为我在本地使用Ruby 2.1.5，并且必须在生产中使用2.0.0。之后，即使我使用了rails快速启动，我也必须运行gem install rails。最后我不得不手动添加到Gemfile gem 'nokogiri'。最后，我可以运行bundle install，应用程序开始工作。

Answer 1

您可以通过以下方式简单地解决错误

 group :doc do
    gem 'sdoc', '~> 0.4.0'
 end

对于平台

platforms :jruby, :mingw, :mswin do
  gem 'tzinfo-data'
end

将Gemfile.lock移除为You have already activated rack 1.5.2, but your Gemfile requires rack 1.6.0

然后检查bundle install

Answer 2

我ssh到$ app_root目录

gem install rack

它有效

Answer 3

确保您的分支用于部署

rhc app-configure --deployment-branch [BRANCH]

然后在您的开发环境中更新gems

#bund install

它会改变Gemfile.lock

$ git add -A $ git commit -am“更新gemfile” $ git push

等到部署更新

Answer 4

我在这里尝试了大部分解决方案，但我仍然陷入困境。问题是为正在使用的当前版本的ruby安装bundle。您将需要在app-root / runtime / repo中执行gem install bundler。然后RAILS_ENV=production bundle exec rails console
