上午手贱，将Mackbook升级到了Yosemite 10.10.1，结果启动iTerm后，直接就报如下错误：
dyld: Library not loaded: /usr/local/lib/libgdbm.1.dylib Referenced from: /usr/local/bin/zsh Reason: image not found
虽然不影响使用，但看起来实在别扭，于是引起强迫症病发，遂开始修复这个问题。一通乱搜后，大神们都建议link一下，我就执行了下brew link pcre，又是报错：
~ brew link pcre Linking /usr/local/Cellar/pcre/8.36... Error: Could not symlink lib/pkgconfig/libpcre.pc /usr/local/lib/pkgconfig is not writable.
好吧，没有权限，那把Owner改成当前用户总是没问题的吧!
~ chown -R $USER:admin /usr/local/lib/pkgconfig
重新link，这次成功了：
~ brew link pcre Linking /usr/local/Cellar/pcre/8.36... 133 symlinks created
不放心又reinstall了一下：
~ brew reinstall pcre ==> Reinstalling pcre ==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/pcre-8.36.yosemite.bottle.tar.gz Already downloaded: /Library/Caches/Homebrew/pcre-8.36.yosemite.bottle.tar.gz ==> Pouring pcre-8.36.yosemite.bottle.tar.gz /usr/local/Cellar/pcre/8.36: 146 files, 5.9M
重新打开了一下iTerm，终于不再报那个错了。强迫症的威力真是无穷啊！！！
