Question

我一直收到以下错误。我有rvm 1.25.17（稳定版），ruby 2.1.0p0修订版44422.另外，我检查了我的Xcode安装，我认为它是最新的（3.2 in / Developer和5.0.2 in / Applications）。在某些时候，错误告诉我可能没有安装我的Xcode。经过长时间的休息后，我又回到了编程状态并且不知所措。只是试图在一些Ruby on Rails上进行设置......

Answer 1

从XCode 5.0.1开始，您可以从终端安装命令行工具。这是命令，请在终端上运行：

xcode-select --install

安装完毕后，请尝试重新安装宝石。

Answer 2

基本上，原子宝石希望你有像gcc 4.2这样的开发者工具，你可以安装查看brew，或者只是像工具一样安装XCode命令，通过rvm重新安装ruby然后安装rails。

Answer 3

您可能缺少gcode和make所需的Xcode命令行工具。从Xcode安装相同的＆gt;首选项＆GT;下载，或者从命令行使用xcode-select --install，然后重试安装Rails。

无法在我的系统上安装Rails
