请帮我找出为什么我无法在运行Ubuntu 14.04的系统中安装bcrypt。
错误：
somehostname@somehost:~$ pip install bcyrpt

我认为错误不是因为警告，因为这不是该行“Could not find a version that satisfies the requirement bcyrpt (from versions: )”所说的。请告诉我问题出在哪里，为什么会出现这个问题？如何解决这个问题？
我已经尝试过以下方法：
1. pip install --pre bcrypt 2. pip install bcrypt==2.0.0
注意：我已按照 github 存储库中所需并提及的所有依赖项安装，并且我的实例在运行 ubuntu 14.04 的 AWS t2.micro 实例上，具有 1 GB Ram。这只是额外的信息。
