使用MacPort安装软件报错解决

报错：
ash-3.2$ sudo port install wget
Password:
Warning: xcodebuild exists but failed to execute
Warning: configured user/group adm does not exist, will build as root
Warning: Xcode appears to be installed but xcodebuild is unusable; some ports will likely fail to build.
Warning: You may need to run `sudo xcode-select -switch /Applications/Xcode.app`
--->  Computing dependencies for wget

解决方式：

1、打开终端，执行：

xcode-select --install

若是已安装会提示xcode-select: error: command line tools are already installed, use "Software Update" to install updates。

若未安装，则会弹出安装窗口，输入密码安装即可。

2、待安装完成，在终端执行：

sudo xcode-select -switch /Applications/Xcode.app

3、在终端执行：

which xcodebuild

提示：/usr/bin/xcodebuild

在终端执行

/usr/bin/xcodebuild

提示：error: can't exec '/Developer/usr/bin/xcodebuild' (No such file or directory)

xcode-select。
