PHP artisan key:generate does not update .env file (laravel 5.2 on AWS EC2 Ubuntu)

Question

I renamed my example.env to .env in order to remove previous errors with my application. However, I noticed

APP_KEY=SomeRandomString

near the top of the .env file an new something was off. When I run

PHP artisan key:generate and recheck the .env file...nothing happens.

My stack includes Apache2, Ubuntu Server 14.04 LTS (HVM), PHP 5.5.36

看起来Laravel仍然使用旧的.env文件，即使该文件已被删除，也可以尝试使用php artisan optimize .env优化类加载php artisan optimize然后重新生成密钥。
