我对Python比较陌生,我正在尝试将Flask应用程序部署到AWS Beanstalk。我遵循官方教程,浏览了很多关于在Beanstalk上使用Flask/Django的部署问题的在线资源(这里或其他地方)。没有成功,我不断收到我无法修复的错误。 下面我的应用程序的结构:Flask Beanstalk部署错误
|-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文件的前几行包含瓶应用的声明:
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)
最后内容/var/log/eb-activity.log

而且我requirements.txt:

user-agents==1.1.0

visitor==0.1.3
webencodings==0.5.1
Werkzeug==0.12.2
WTForms==2.1
我有没有青苗配置文件(还),但我已经进行手动安装的:yum install libffi-devel
我的第一个问题是,我们如何确定,当我们需要将-devel
包添加到我们的部署? (我通过安装上面的devel软件包解决了第一个部署问题。) 我认为所有必需的软件包/库都将与requirements.txt一起安装?
我的第二个问题是你有任何线索,为什么这个部署失败? (有望被链接到的第一个问题?)
在此先感谢您的帮助,
STF
嗨@Igor T.,谢谢。 我刚刚尝试过,部署仍然失败,我有同样的错误。 –
