Rails中的“安装json（1.8.0）时发生错误，并且Bundler无法继续”

Question

我得到了一个使用Ruby on Rails构建的网站。 我认为该网站大约建于3年前。 我试图在本地计算机上启动并运行它，但是在尝试运行服务器时遇到一些错误。

版本：Ruby 2.4.0p0

Rails 5.1.1

自制软件1.2.3

Git版本2.11.0

当我运行rails s以下错误：

Could not find proper version of railties (3.2.6) in any of the sources
Run `bundle install` to install missing gems.

当我运行bundle install我得到：

An error occurred while installing json (1.8.0), and Bundler cannot
continue.
Make sure that `gem install json -v '1.8.0'` succeeds before bundling.

我有谷歌的错误，并尝试了各种事情，但仍然没有运气。 有人说将gem'json'，'1.8.0'添加到gem文件中，但还是没有运气

这是gemfile

source 'https://rubygems.org'

gem 'rails', '3.2.6'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'mysql2', '> 0.3'
gem 'bluecloth'
gem 'simple_form'
gem 'carrierwave'
gem 'rmagick'
gem 'capistrano'
gem 'rvm-capistrano'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

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'

这是因为版本不兼容吗？

Answer 1

快速编辑：看来我的以下答案可能是错误的：您需要在json租借v2.0中支持ruby 2.4，如此处所述： https : //github.com/flori/json/issues/303

根据您的gemfile，看起来您的rails版本是3.2.6。 此外，您还有gem rdoc ，它具有以下要求：

rdoc (3.12)
  json (~> 1.4)

这会将您的json gem版本锁定为1.4。 您可能需要使用旧版本的json ，或者更新rails和rdoc来处理它。

Answer 2

尝试使用早期版本的Ruby（通过RBENV或RVM）。 我切换到Ruby 2.1.10，错误消失了。
