ruby-on-rails - Bundler 找不到 gem "nokogiri"的兼容版本

Question

我将 Rails 应用程序推送到 appfog，但收到以下错误消息:

/var/vcap.local/dea/apps/superb-0-dc92a2e492e46c40c06d2abc3ad59841/app/rubygems ruby/1.9.1/gems/bundler-1.1.3/lib/bundler/resolver.rb:129:in `block in resolve' Bundler could not find compatible versions for gem "nokogiri": (Bundler::Versi nConflict) In snapshot (Gemfile.lock): nokogiri (1.5.6) In Gemfile: capybara (= 1.1.2) ruby depends on nokogiri (>= 1.3.3) ruby

Running bundle update will rebuild your snapshot from scratch, using only the gems in your Gemfile, which may resolve the conflict.

和我的 Gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.12'
gem 'mysql2'
gem 'pg'
gem 'thin'
gem 'sqlite3'

group :development, :test do
  gem 'rspec-rails', '2.11.0'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '3.2.5'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.2'

group :test do
  gem 'capybara', '1.1.2'
end

如何解决问题？

编辑:添加 Gemfile.lock

你可以试试这个，

加入你的gemfile

gem 'nokogiri', '1.3.3'

因此您的应用仅使用 nokogiri 1.3.3 而不是最新版本
