An error occurred while installing json (1.8.1), and Bundler cannot continue.
在捆绑之前确保gem install json -v '1.8.1' 成功。
【问题讨论】：
-
运行
gem install json -v '1.8.1'会得到什么？ -
错误：安装 json 时出错：错误：无法构建 gem 原生扩展。
-
gem 列表显示：json (1.8.6, 1.8.3, 1.8.2)
-
你能编辑你的问题并发布整个日志输出吗？很难理解为什么它只在第一行就失败了。另外你在什么操作系统上？什么版本的 ruby 和 bundler？
