我是编程新手，我已经开始安装Ruby on Rails了。我刚刚尝试创建我的第一个项目。 但是每当我尝试在我的项目中捆绑安装时，我都会在标题中收到消息。我正在使用Windows。
当我尝试捆绑安装时

很抱歉，如果我发布了这个错误。谢谢！
答案 0 :(得分：0)
当您看到消息时：
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
很可能无法构建本机扩展，因为某些系统库存在问题，甚至是您的Ruby / DevKit版本。
我不熟悉Windows上的Ruby，在我第一次使用Rails时切换到了OSX。
在您的情况下，我发现了类似的question 可能可以帮助您。
