Question

我试图在弹性beanstalk实例上安装peewee包以控制瓶子应用程序。我认为问题在于MySQL-python依赖，但是peewee也没有加载。我的需求文件如下所示：

bottle==0.11.6
peewee==2.1.1
MySQL-python

我还尝试MySQL-python作为MySQL-python==1.2.4b4。由于我认为总结here的一些原因，这不起作用; peewee没有安装，我在日志中收到此错误消息：

所以pip对这些软件包不起作用。我非常确定我可以通过连接到EC2实例并安装没有pip的MySQL-python来解决这个问题，但在我看来，它会破坏弹性beanstalk的目的，因为每次新实例启动它都需要我进去并手动修补它。我有办法解决这个问题吗？我也有同样的问题试图安装像scipy和matplotlib这样的东西，所以广泛地说，有没有办法可以在没有pip的弹性beanstalk实例上安装python包，而不是单独进入每个实例？我应该研究如何制作自定义AMI并在beanstalk上使用它？非常感谢，亚历

抱歉，我忘了我问过这个问题。我最终通过ssh进入实例并使用easy_install而不是pip安装MySQL-Python来解决这个问题。

基本上我去了python虚拟环境方向：

opt/python/run/venv/bin

并使用easy_install安装版本1.2.3：

sudo ./easy_install MySQL-Python==1.2.3

我通过尝试在虚拟环境的python中导入MySQLdb来检查它是否已安装：

./python

>>>import MySQLdb
>>>

它对我有用。然后我通过弹性beanstalk命令行工具再次推送它来重置服务器：

git aws.push

就是这样。有点烦人，但是在新实例启动时它似乎仍然有用。

谢谢，亚历
