当我尝试创建新的rails项目时，我面临与缺少json gem相关的错误。

当我尝试安装json gem时，会发生以下错误：

Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing json:
        ERROR: Failed to build gem native extension.

Answer 1

如果要在Windows 7（64位）上安装Ruby 2（或更高版本），则还需要安装DevKit 64位。您的Devkit必须与您的操作系统兼容。

因此，请确保在系统上安装了正确的Ruby和兼容的Devkit。

有关详细信息，请参阅this tutorial。

Answer 2

有一组宝石依赖在一起。所以，我必须一步一步地安装。

正如我根据错误消息一个接一个地做的那样，我忘了记下这些步骤。
