Library not loaded…/libicui18n.63.dylib

使用hexo s时出现这个问题

dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.63.dylib
  Referenced from: /usr/local/bin/node
  Reason: image not found

我还以为没有装node呢，brew list后发现

apr			jansson			ncurses

有node,百度了一下，原因差不多就是系统更新后，新系统不兼容node插件，node也需要更新一下，兼容新系统

brew cleanup
brew upgrade node

这样OK了
