Question

我使用以下链接来解决问题。但是还有其他一些问题。

gem install json -v 1.7.3 gives 'Please update your PATH to include build tools'

`enter code here`C:\>ruby dk.rb init
[INFO] found RubyInstaller v2.2.4 at C:/Ruby22

初始化完成！请查看并修改自动生成的内容 'config.yml'文件，以确保它包含所有的根目录您想要通过DevKit增强安装的Rubies。

我不知道我应该做出什么改变以及如何改变。

C:\>ruby dk.rb install

你能帮我解决这个问题。我一直在尝试解决这个问题一个月。谢谢。

Answer 1

您似乎已经安装了DevKit，因此出现错误消息

您必须先安装开发工具。

表示您的Ruby版本与DevKit版本不匹配。确保两者都是64位，或两者都是32位版本，并选择与您的操作系统匹配的任何一种。

与安装Ruby有关的问题
