我有部署瓶应用到AWS EC2实例的问题。 可能与pip安装lxml 。 但我不知道如何解决这个问题。
AWS EC2：
Platform: 64bit Amazon Linux 2015.03 v1.4.6 running Python 2.7
从CLI对eb create ：
CalledProcessError: Command '/opt/python/run/venv/bin/pip install -r /opt/python/ondeck/app/requirements.txt' returned non-zero exit status 1.
从日志：

首先，我说的对与安装问题lxml ？ 如果是这样，你知道如何解决这个问题的AWS，因为我的本地计算机上（的Mac OS 10.9.5）我没有这个错误。
