我在rails应用程序中运行bundle install时收到以下错误消息：
An error occurred while installing json (1.8.1), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.1'` succeeds before bundling.
然后我运行gem install json -v '1.8.1'
并收到此错误：

我试过评论宝石'jbuilder'，'〜＆gt; 2.0'
但我仍然得到同样的错误。
不确定我在这里做错了除了我认为可能存在一些依赖性问题，因为我的gem文件中甚至没有json 1.8.1。谢谢你的帮助。
答案 0 :(得分：1)
根据这个thread，您可能需要将json升级到1.8.3才能使用ruby 2.2进行编译（我假设您使用的是2.2）
要更新json，请先尝试使用以下命令安装：
gem install json -v '1.8.3'
之后，使用
更新Gemfile中的json gem
bundle update json
如果它不起作用，那么你可能需要更新你的Gemfile中需要json＆lt;的其他gem。 1.8.3（例如，我可以在Gemfile.lock中看到sdoc (0.4.1)）。尝试运行bundle update（没有参数）。
我还建议更新bundler和rubygems。
