ruby-on-rails – Bundler找不到gem“activesupport”和“railties”的兼容版本

我在Win 8 PC上成功安装了Railsinstaller并启动了一个项目.我设置了 github并将项目推送到它.在第一台电脑上,一切都在找工作.然后我在第二台Win 8 PC上安装了Railsinstaller.在第二台PC上,我运行了gem update rails.然后我运行了git clone [url],这也很成功.但我无法启动rails服务器,因为缺少gem.这是gem列表的输出：

我试过捆绑安装：

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    rspec-rails (= 2.6.1) x86-mingw32 depends on
      railties (~> 3.0) x86-mingw32

    sass-rails (~> 4.0.0) x86-mingw32 depends on
      railties (4.0.0)

和捆绑更新：

Bundler could not find compatible versions for gem "activesupport":
  In Gemfile:
    rspec-rails (= 2.6.1) x86-mingw32 depends on
      activesupport (~> 3.0) x86-mingw32

    rails (= 4.0.0) x86-mingw32 depends on
      activesupport (4.0.0)

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    rails (= 4.0.0) x86-mingw32 depends on
      railties (= 4.0.0) x86-mingw32

    sass-rails (~> 4.0.0) x86-mingw32 depends on
      railties (4.0.0.rc2)

但这没有帮助.我也删除了gemfile.lock并运行了上面提到的命令,但仍然没有运气.我觉得奇怪的是它抱怨了宝石的版本冲突,但是当我查看gem文件时,我看到所有必需的版本都已安装.你能不能指出我可能做错了什么,因为我完全没有想法？谢谢.

更新：

这是我的gemfile：

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails',github: 'rails/rails'
gem 'rails','4.0.0'

# Use sqlite3 as the database for Active Record
#gem 'sqlite3'

# Use SCSS for stylesheets
gem 'sass-rails','~> 4.0.0'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier','>= 1.3.0'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails','~> 4.0.0'

# 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','~> 1.2'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc',require: false
end

# Use ActiveModel has_secure_password
# gem 'bcrypt-ruby','~> 3.0.0'

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

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

# Use debugger
# gem 'debugger',group: [:development,:test]

group :development do
  gem 'sqlite3'
  gem 'rspec-rails','2.6.1',:require => 'rspec-rails'
  gem 'faker','0.3.1'
end

group :test do
    gem 'sqlite3'
    gem 'rspec-rails',:require => 'rspec-rails'
    gem 'webrat','0.7.1'
    gem 'factory_girl_rails','1.0'
    gem 'turn',:require => false
end

group :production do
    gem 'pg'
end

解决方法

如果bundle说它无法找到兼容的gem版本,那可能是因为它无处可寻.你给它版本号,即强制它为每个宝石采取某些版本,或者优于X,或低于X的版本.

尝试从Gemfile中删除罪魁祸首宝石的版本号,然后重试：

gem 'rspec-rails'

代替

gem 'rspec-rails','2.6.1'
