解决Mac安装thrift因bison报错的问题

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
