我运行laravel new auth，得到以下错误。如果有帮助的话，我用的是Windows 7。
C:'wamp'www>laravel new auth

取消php.ini中的以下行注释
;extension=php_mbstring.dll
;extension=php_exif.dll ; Must be after mbstring as it depends on it
;extension=php_mysql.dll
;extension=php_mysqli.dll
重新启动apache。
Mbstring是创建强散列所必需的
删除C:'wamp'www'auth'bootstrap'cache'这个目录下的所有文件，然后运行
composer install
