MacPorts 迁移至 EI Capitan

老版本的MacPorts在EI Capitan下有兼容性问题。今天运行报错如下：

Error: Current platform “darwin 15” does not match expected platform “darwin 14” Error: If you upgraded your OS, please follow the migration instructions: https://trac.macports.org/wiki/Migration OS platform mismatch while executing “mportinit ui_options global_options global_variations” Error: /opt/local/bin/port: Failed to initialize MacPorts, OS platform mismatch

参考之进行重新安装，依次执行命令：

xcode-select —install
xcodebuild -license

从官网下载安装包： https://www.macports.org/install.php

直接利用安装包安装即可。
