我对Python比较陌生，我正在尝试将Flask应用程序部署到AWS Beanstalk。我已经按照官方教程浏览了大量有关Beanstalk上Flask / Django部署问题的在线资源（此处或其他地方）。没有成功，我不断得到我无法解决的错误。在我的应用程序结构下面：
|-application.py
|-config.py
|-const.py
|-requirements.txt
|-app/
|--__init.py__
|--views.py
|--models.py
|--static/
|--templates/
我的application.py
from app.views import application
application.run(debug=False)
我的views.py文件的前几行包含Flask应用程序的声明：
from flask import Flask, render_template, redirect, url_for, session, request, abort
from flask_bootstrap import Bootstrap
from . models import Datalayer, Config, Signin
from . util import check_user
from flask_basicauth import BasicAuth
from flask_bcrypt import Bcrypt
from faker import Faker
from htmlmin.minify import html_minify
fake = Faker()
application = app = Flask(__name__)
app.config.from_object('config')
bootstrap = Bootstrap(app)
basic_auth = BasicAuth(app)
bcrypt = Bcrypt(app)
最后是/var/log/eb-activity.log的内容

和我的requirements.txt：
appdirs==1.4.3

user-agents==1.1.0
uuid==1.30
visitor==0.1.3
webencodings==0.5.1
Werkzeug==0.12.2
WTForms==2.1
我没有beanstalk配置文件（但）我已经执行了手动安装：yum install libffi-devel
我的第一个问题是我们如何确定何时需要在部署中添加-devel包？ （我修复了上面安装devel包的第一个部署问题。）我假设所有必需的包/库都将与requirements.txt一起安装？
我的第二个问题是你有什么线索为什么这个部署失败了？ （希望能与第一个问题挂钩？）
在此先感谢您的帮助，
STF
尝试从requirements.txt中删除以下行
uuid==1.30
uuid与2.5版左右捆绑在一起。
