To enable extensions, verify that they are enabled in your .ini files:
– /usr/local/php/etc/php.ini
You can also run `php –ini` inside terminal to see which files are used by PH P in CLI mode.

./configure –with-php-config=/usr/local/php/bin/php-config

make

make install

再到 php.ini 中开启fileinfo

composer
