你应该改变目录的所有权，让你的当前用户作为所有者，webserver用户（www-data，apache，...）作为组。
chown -R $user:www-data [推荐]。
设置当前用户为所有者，webserver用户为组。
$ sudo chown -R $USER:www-data storage
$ sudo chown -R $USER:www-data
bootstrap/cache 设置目录权限为775
$ chmod -R 775 storage
$ chmod -R 775 bootstrap/cache
chown -R 777 [不推荐]
你可以将两个目录设置为777。
$ chmod -R 777 storage
$ chmod -R 777 bootstrap/cache
