To enable extensions, verify that they are enabled in your .ini files:
- D:\phpstudy\PHPTutorial\php\php-7.2.1-nts\php.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
方法
我的本地是7.0.1，而下载下来的原来是运行在7.0.8版本的，
于是执行:composer install 时，报了一堆错。解决办法：删掉composer.lock,重新composer install
