当我运行只是创业板安装JSON它安装细带我在第2版但我想安装此https://github.com/peatio/peatio，它特别需要该版本。

还有其他想法吗？

只是一个猜测：由于红宝石已经内置JSON，我不认为比赛笔者预计，只有人用一个很老的Ruby版本（1.7，也许1.8）使用宝石，和本机C接口不适用于较新的Ruby版本。请问你为什么要使用的宝石，当你在Ruby标准库中有JSON了吗？ – user1934428

我不想使用自己的宝石，但它是在创业板depencie我要安装并在创业板上市的文件我找不到它删除，要么：| – velua

的问题的出现是由于你是不是在正确的目录。请到您的轨道目录文件夹，然后先运行此命令是这样的：

轨@轨：〜/ rails_project/BTC $创业板安装JSON -v“1.8.1” 那么它的做工精细。
