如何在Windows上为ruby安装’byebug’？

我是ruby的新手并尝试设置我的开发环境（Windows 10）。 我已经安装了ruby和rails但是无法安装byebug。 从我读到的，我首先需要DevKit。 所以我按照这里的指南安装它：

https://github.com/oneclick/rubyinstaller/wiki/Development-Kit

然后尝试安装gem但没有运气。 我试图卸载然后强制安装DevKit但仍然无法安装byebug。 这就是我所看到的：

C:\RubySDK>gem install byebug Temporarily enhancing PATH to include DevKit... Building native extensions. This could take a while...

还有另一种方法吗？ 谢谢

Answer 1

你必须像这样安装版本：

gem install byebug -v 5.0.0

如果您需要更多信息，请点击链接

Answer 2

我知道这是迟到的回复！

但是当你遇到DevKit的困难时，在这种情况下使用诸如buybug或json之类的本机gem，你必须知道如果你的System类型是64位， 你必须使用RubyInstaller 64位和DevKit 64位。 遵循32位系统类型的相同原则，使用RubyInstaller 32位和DevKit 32位 。

另外，在安装，ruby和rails以及DevKit之后不要忘记运行几个命令，为此通过终端（Windows中的cmd）永久安装DevKit并运行：

命令：

1. ruby dk.rb init – 这将创建配置文件
2. 然后运行ruby dk.rb install

干杯和快乐的编码。 Ibrax。

发现了问题。 看起来我使用的是错误的DevKit版本。 我安装了32位ruby时安装了64位
