mac os升级到10.12.5后,编译PHP扩展无权限？
最后一步报错

sudo make install
Installing shared extensions:     /usr/lib/php/extensions/no-debug-non-zts-20131226/
cp: /usr/lib/php/extensions/no-debug-non-zts-20131226/#INST@79807#: Operation not permitted
make: *** [install-modules] Error 1

出现了没权限,我打算将/usr/lib/php/extensions/权限修改为777,
但是

sudo chmod -R 777 extensions/
Password:
chmod: Unable to change file mode on extensions/: Operation not permitted

已经是root身份操作,有没有遇到的？？
