MAC OSX php dyld: Library not loaded: /usr/local/xxxx.dylib

今天折腾一个叫vips的图像处理扩展,安装官方流程执行 brew install vips 没任何报错, 然后 pecl install vips 就发生报错

dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.62.dylib
  Referenced from: /usr/local/bin/php
  Reason: image not found
[1]    11703 abort      php -m

然后执行php各种命令都报这个错误 , 上网查了下说是icu4c 这个依赖的问题,
brew info icu4c 查看这个库的详情

很明显问题原因出来了:版本问题,我现在的版本是63.1,php需要的版本是 62,估计是我安装其他依赖的时候自动给我升级的吧,切换过来就行了
brew switch icu4c 62.1
