Flask Beanstalk部署错误 [英] Flask Beanstalk deployment errors

问题描述

我对Python比较陌生，我正在尝试将一个Flask应用程序部署到AWS Beanstalk。我遵循官方教程，并在网上（在这里或其他地方）了解了关于Flask / Django on Beanstalk的部署问题的大量资源。没有成功，我不断收到我无法修复的错误。
在我的应用程序的结构之下：

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

My application.py

  from app.views import application 
 
 application.run（debug = False）
  

包含Flask应用程序声明的views.py文件的前几行：

  from flask import Flask，render_template，redirect，url_for，session，request，abort $ b $ from flask_bootstrap import Bootstrap 
来自。模型导入数据层，配置，签署
从。 util import check_user $ b $ from flask_basicauth import BasicAuth $ b $ from flask_bcrypt import bcrypt $ b $ from faker import faker 
 from htmlmin.minify import html_minify 
 fake = Faker（）
 
 
 application = app = Flask（__ name__）
 app.config.from_object（'config'）
 
ootstrap = Bootstrap（app）
 basic_auth = BasicAuth（app）
 bcrypt = Bcrypt（app）
  

最后， code> /var/log/eb-activity.log

 uuid == 1.30 
 visitor == 0.1.3 
 webencodings == 0.5。 1 
 Werkzeug == 0.12.2 
 WTForms == 2.1 
  

我有没有beanstalk配置文件（但），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将 -devel 包添加到我们的部署中？ （我在上面安装了devel包，解决了第一个部署问题。）
我认为所有必要的包/库都将与requirements.txt一起安装吗？

我的第二个问题是，你有什么线索，为什么这个部署失败？ （有希望被链接到第一个问题？）

在此先感谢您的帮助，

解决方案

尝试从您的requirements.txt中移除以下行：

<$ p $ uuid == 1.30


uuid 与2.5版本的Python捆绑在一起。

I am relatively new to Python and I am trying to deploy a Flask app to AWS Beanstalk. I have followed the official tutorial and went through a lot of the resources available online (here or elsewhere) regarding deployment issues with Flask / Django on Beanstalk. No success, I keep getting errors I cannot fix. Below the structure of my app:

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

My application.py

from app.views import application

application.run(debug=False)

The first few lines of my views.py file that contains the declaration of the Flask app:

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)

And finally the content of the /var/log/eb-activity.log

uuid==1.30
visitor==0.1.3
webencodings==0.5.1
Werkzeug==0.12.2
WTForms==2.1

I have no beanstalk config file (yet) but I have performed a manual install of: yum install libffi-devel

My first question is how do we determine when we need to add -devel packages to our deployment? (I fixed a first deployment issue with the installation of the devel package above.) I assumed all the necessary packages / libraries would be installed with the requirements.txt?

My second question is do you have any clue as to why this deployment is failing? (will hopefully be linked to the first question?)

Thanks in advance for the help,

Stf

解决方案

Try removing the following line from your requirements.txt

uuid==1.30

uuid is bundled with Python as of version 2.5 or so.
