Flask Beanstalk部署錯誤

Question

我對Python比較陌生，我正在嘗試將Flask應用程序部署到AWS Beanstalk。我遵循官方教程，瀏覽了很多關於在Beanstalk上使用Flask/Django的部署問題的在線資源（這裏或其他地方）。沒有成功，我不斷收到我無法修復的錯誤。 下面我的應用程序的結構：

|-application.py 
|-config.py 
|-const.py 
|-requirements.txt 
|-app/ 
|--__init.py__ 
|--views.py 
|--models.py 
|--static/ 
|--templates/ 

我application.py

from app.views import application 

application.run(debug=False) 

我views.py文件的前幾行包含瓶應用的聲明：

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)

而且我requirements.txt：

appdirs==1.4.3 
bcrypt==3.1.3 
beautifulsoup4==4.6.0 
cffi==1.10.0 
click==6.7 
django-htmlmin==0.10.0 
dominate==2.3.1 
Faker==0.7.12 
Flask==0.12.2 
Flask-BasicAuth==0.2.0 
Flask-Bcrypt==0.7.1 
Flask-Bootstrap==3.3.7.1 
Flask-WTF==0.14.2 
html5lib==0.999999999 
itsdangerous==0.24 
Jinja2==2.9.6 
MarkupSafe==1.0 
packaging==16.8 
pycparser==2.17 
pyparsing==2.2.0 
python-dateutil==2.6.0 
PyYAML==3.12 
requests==2.14.2 
six==1.10.0 
ua-parser==0.7.3 
user-agents==1.1.0 
uuid==1.30 
visitor==0.1.3 
webencodings==0.5.1 
Werkzeug==0.12.2 
WTForms==2.1 

我有沒有青苗配置文件（還），但我已經進行手動安裝的：yum install libffi-devel

我的第一個問題是，我們如何確定，當我們需要將-devel包添加到我們的部署？ （我通過安裝上面的devel軟件包解決了第一個部署問題。） 我認爲所有必需的軟件包/庫都將與requirements.txt一起安裝？

我的第二個問題是你有任何線索，爲什麼這個部署失敗？ （有望被鏈接到的第一個問題？）

在此先感謝您的幫助，

嘗試從requirements.txt刪除以下行

uuid==1.30 

uuid是與2.5版本左右的Python捆綁在一起。
