突然手贱跑了一下brew update，java环境就GG了，
dyld: Symbol not found: __cg_jpeg_resync_to_restart
Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
Expected in: /usr/local/lib/libJPEG.dylib
in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
网上搜索了一下，感觉这种问题都可能出现在各个地方，QT，啥啥的之类，我这次影响到java环境，基本的问题处理方式都是没发现指定的文件，ln引用一下就OK，下面是处理方式，其他的各自找文件引用一下
cd /usr/local/lib mv libjpeg.dylib libjpeg.dylib.backup ln -s /System/Library/Frameworks/ImageIO.framework/Resources/libJPEG.dylib libJPEG.dylib mv libtiff.dylib libtiff.dylib.backup ln -s /System/Library/Frameworks/ImageIO.framework/Resources/libTIFF.dylib libTIFF.dylib mv libpng.dylib libpng.dylib.backup ln -s /System/Library/Frameworks/ImageIO.framework/Resources/libPng.dylib libPNG.dylib
