jruby的新手。我在尝试运行时遇到错误
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 bundle install”，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，并且未对Gemfile进行任何更改。
My Gemfile（自去年10月以来一直没有改变，曾经工作过）：
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'
