mac phpize执行后报错：grep: /usr/include/php/main/php.h: No such file or directory

$ phpize

grep: /usr/include/php/main/php.h: No such file or directory

grep: /usr/include/php/Zend/zend_modules.h: No such file or directory

grep: /usr/include/php/Zend/zend_extensions.h: No such file or directory

Configuring for:

PHP Api Version:        

Zend Module Api No:     

Zend Extension Api No:

缺少PHP的header头文件，再一看/usr/include文件夹根本不存在敲出如下命令：

$ xcode-select --install

xcode-select: note: install requested for command line developer tools

如果phpize还是无效、执行下列命令安装header头文件SDK即可：

$ cd /Library/Developer/CommandLineTools/Packages/

$ open macOS_SDK_headers_for_macOS_10.14.pkg
