无法安装特定的宝石

我有我试图启动和运行，但是当我尝试迁移数据库，它说的exsisting Ruby on Rails项目：无法安装特定的宝石

$ rake db:migrate 

Could not find json-1.6.5 in any of the sources

当我再尝试安装特殊的宝石，它失败了！

$ gem install json -v '1.6.5'

我认为你需要安装系统相关的包libjson，红宝石红宝石。安装这个软件包将解决这个错误。

试过gem install libjson-ruby，但没有找到它。当我谷歌 - 它看起来像它是Debian的宝石。我正在运行Mac.And当我做一个宝石名单--remote json没有任何东西叫做libjson-ruby – lmkk

它看起来像你缺少一些命令行工具。

验证是否已安装使

$ whereis make

应该返回类似：

/usr/bin/make

和

$ make -v

应该类似于：
