Xcode6.4安装CommandLineTools

本文介绍了一种在Xcode 6.4及以上版本中安装CommandLineTools的方法。由于直接通过Xcode的偏好设置无法找到该工具,文章提供了一个替代方案:通过Xcode的菜单栏打开更多开发者工具,并从官方网站下载对应的版本。

因为编译FFMPEG需要用到CommandLineTools,所以需要安装这个工具,但是网上都说在Xcode上Preferences > Downloads > Components 中安装。但是根本找不到这个工具。

这里提供Xcode6.4(往上的版本应该也可以)安装CommandLineTools的办法



进入Xcode,菜单栏->Xcode->Open Developer Tool,点击More Developer Tools...,到官网上下载,下载的时候注意版本和Xcode对应
