macOS，Rails:“无法构建gem本机扩展" [英] macOS, Rails: "Failed to build gem native extension"

问题描述

我一直在尝试在Mac上安装滑轨.我有OS X 10.6.8，并且已经确认我有Ruby，版本1.8.7

I'm stuck trying to install rails on my mac. I have OS X 10.6.8 and I have confirmed that I have Ruby, version 1.8.7

我运行了 sudo gem update 和 sudo gem update --system 以获得该软件的最新版本.

I ran sudo gem update and sudo gem update --system to get the latest versions of the software.

但是，当我运行 sudo gem install rails 时，出现此错误:

However, when I run sudo gem install rails I get this error:

ERROR:  Error installing rails:
ERROR: Failed to build gem native extension.

推荐答案

如果您具有XCode 4或更高版本，则需要将其打开并转到首选项"->下载"->组件"并按原样安装命令行工具.•默认情况下已安装.在发生这种情况之前，无法安装Rails.

If you have XCode 4 or later you will need to open it and go to Preferences -> Downloads -> Components and install the Command Line tools as they aren't installed by default. Couldn't install Rails until this happened.
