Mac下提示autom4te: need GNU m4 1.4

解决问题：

先 mv /Applications/MAMP/Library/bin/m4 /Applications/MAMP/Library/bin/m4_backup

brew reinstall m4

echo 'export PATH="/usr/local/opt/m4/bin:$PATH"' >> ~/.zshrc
或者 
echo 'export PATH="/usr/local/opt/m4/bin:$PATH"' >> ~/.bash_profile 
依据自己的环境配置

进行重新编译

软连接到指定位置
ln -s /usr/local/opt/m4/bin/m4 /Applications/MAMP/Library/bin/m4

./phpize
