在这次部署和上次部署之间，安装一个软件包boto似乎安装了许多其他依赖项，这些依赖项最终阻止EB从requirements.txt安装所有软件包

这是我当前的requirements.txt：

appdirs==1.4.3
beautifulsoup4==4.5.3
blessed==1.14.2
boto==2.46.1
cement==2.8.2
colorama==0.3.7

如果您有任何帮助，我们将不胜感激

您似乎需要先安装g++程序。我是否应该将g++添加到需求中？您如何设置这台机器？最终，你得到了一个Python包（Python CRFSu套），它不是100%纯Python，它需要一个C++编译器。Elastic Beanstalk机器可以有一个类似于

apt get install g++

（对于基于Ubuntu的机器，或者对于基于CentOS的机器，

yum install gcc-c++

）。
