安装thrift时，报错：
Bison version 2.5 or higher must be installed on the system!
使用brew install bison 安装新版的bison
$ brew list bison
/usr/local/Cellar/bison/3.0.4/bin/bison
/usr/local/Cellar/bison/3.0.4/bin/yacc
/usr/local/Cellar/bison/3.0.4/lib/liby.a
/usr/local/Cellar/bison/3.0.4/share/aclocal/bison-i18n.m4
/usr/local/Cellar/bison/3.0.4/share/bison/ (23 files)
/usr/local/Cellar/bison/3.0.4/share/doc/ (14 files)
/usr/local/Cellar/bison/3.0.4/share/info/bison.info
/usr/local/Cellar/bison/3.0.4/share/man/ (2 files)
已经安装3.0.4版本
但是安装thrift，仍然报错
Bison version 2.5 or higher must be installed on the system!
经查是使用了xcode自带的bison，路径 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/
解决办法：
首先将bison改名
cd /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/
sudo mv bison bison111
然后新版本的bison复制到路径下
sudo cp /usr/local/Cellar/bison/3.0.4/bin/bison /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/
再次安装thrift，安装成功。
cd /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/
sudo rm bison
sudo mv bison111 bison
