ruby-on-rails – Openshift上的Ruby“bundle install”错误

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但是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并且Open shift默认运行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文件放在哪里.我试着把它放在/var/lib/openshift/xxxxxxxxxxxxxxxxxxxxxxxxxx/app-root/runtime/repo/.openshift/action_hooks/下.但我不确定运行时是否是正确的回购.

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]

解：

正如@Rajarshi Das所说我必须改变

gem 'sdoc',group: :doc

成

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

我不知道为什么.也许是一些语法问题,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.之后我不得不运行gem install rails,即使我使用了rails快速启动.最后我不得不手动添加到Gemfile gem’nokogiri’.最后我可以运行bundle install并开始运行应用程序.

解决方法

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

删除Gemfile.lock,因为您已经激活了机架1.5.2,但您的Gemfile需要机架1.6.0

然后检查捆绑安装
