jruby Bundler 找不到兼容的 json 版本

Question

jruby的新手。 尝试运行时出错

jruby -S bundle exec rake assets:precompile
Bundler could not find compatible versions for gem "json":
  In snapshot (Gemfile.lock):
    json (1.8.1)
  In Gemfile:
    carrierwave (>= 0) ruby depends on
      json (>= 1.7) ruby

我尝试删除 Gemfile.lock 并运行"jruby -S 捆绑包安装"，但没有帮助。

我在Mac上使用jruby 1.7.3和ruby 1.8.7。 我之前已成功运行预编译，并且没有对 Gemfile 进行任何更改。

我的宝石文件（自去年 10 月以来没有更改过，曾经工作）：

source 'https://rubygems.org'
gem 'rails', '3.2.13'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'activerecord-jdbcmysql-adapter'
gem 'jruby-openssl'
gem 'mini_magick'
gem 'carrierwave'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'bourbon'
  #gem 'coffee-rails', '~> 3.2.1'
  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  gem 'therubyrhino'
  gem 'uglifier', '>= 1.0.3'
end
gem 'uuidtools'
gem 'amazon-ses-mailer'
gem 'jquery-rails'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'debugger'

谢谢

这

看起来像是一个捆绑器问题。将捆绑程序更新到 1.5.2 并重试：

jruby -S gem install bundler
