尝试将Flask应用程序部署到AWS Elastic Beanstalk时出错 [英] Error when Trying to Deploy Flask App to AWS Elastic Beanstalk

问题描述

我尝试使用AWS Elastic Beanstalk部署一个Flask应用程序，不幸的是，遇到以下错误。我感到困惑的是，在我的虚拟环境和本地机器的当前版本的点是9.0.1，所以我不知道为什么它正在接受7.1.2。

 命令/opt/python/run/venv/bin/python2.7 -cimport setuptools，tokenize; __ file __ ='/ tmp / pip-build-L32BGc / cffi / setup。 py'; exec（compile（getattr（tokenize，'open'，open）（__ file __）.read（）.exc（'\r\\\

'），__file__，'exec'）） install --record /tmp/pip-nO55i_-record/install-record.txt --single-version-external-managed -compile --install-headers / opt / python / run / venv / include / site / python2 .7 / cffi失败，错误代码1在/ tmp / pip-build-L32BGc / cffi 
中您正在使用pip版本7.1.2，但是可以使用9.0.1版本。 
您应该考虑通过pip install --upgrade pip命令进行升级。

解决方案

ersion太旧了。你可以添加 .ebextensions 来解决这个问题。
$ b

1. add .ebextensions 文件夹放在您的应用程序的根目录下


2. 在里面放置一个 pip.config 文件，内容是：
   
   
   $ $ $
   
   $ b update_pip
   命令：/ opt / python / run / venv / bin / pip install --upgrade pip
   

   
   
   

   
   
   3. 再次执行eb部署，将会解决。
   
   

   
   

   I am trying to deploy a Flask application using AWS Elastic Beanstalk and unfortunately have run into the following error. What confuses me is that the current version of pip in my virtual environment and local machine is 9.0.1, so I am not sure why it is picking up 7.1.2.

   Command "/opt/python/run/venv/bin/python2.7 -c "import setuptools, tokenize;__file__='/tmp/pip-build-L32BGc/cffi/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-nO55i_-record/install-record.txt --single-version-externally-managed --compile --install-headers /opt/python/run/venv/include/site/python2.7/cffi" failed with error code 1 in /tmp/pip-build-L32BGc/cffi
     You are using pip version 7.1.2, however version 9.0.1 is available.
     You should consider upgrading via the 'pip install --upgrade pip' command.

   解决方案

   This is because the pip version is too old. you can add .ebextensions to solve this.

   1. add .ebextensions folder in the root folder of your app
   2. put a pip.config file inside it, the content is :

   
   commands:
     update_pip:
     command: "/opt/python/run/venv/bin/pip install --upgrade pip"
   

   3. run eb deploy again, it will be resolved.
