将 django 应用程序部署到 aws beanstalk 时的 requirements.txt 无效 [英] Invalid requirements.txt on deploying django app to aws beanstalk

问题描述

在我最近一次提交之前，我一直在将我的应用程序部署到 beanstalk 环境中，没有任何问题.

I have been deploying my app without any issues to the beanstalk environment until my latest commit.

现在我明白了

快照日志是这样写的:

我的requirements.txt和以前一样.我也尝试删除 requirements.txt 中的所有内容，但我再次遇到相同的错误，这让我认为问题出在运行 requirements.txt 之前.

My requirements.txt is the same as before. I tried removing everything in the requirements.txt as well but I get the same error again which makes me think the problem was before requirements.txt was run.

我不知道事物的部署顺序.无论如何，这是我的配置文件:

I don't know the order in which things are deployed. ANyway, here is my config file:

packages:
  yum:
    libjpeg-devel: '6b'
    zlib-devel: []
    freetype-devel: []


container_commands:
  01_install_mysqldb:
    command: "pip install distribute==0.6.28; pip install mysql-python;"

    leader_only: true
  03_createadmin:
    command: "python scripts/createadmin.py"
    leader_only: true
  04_collectstatic:

  10_migrate_actstream:
    command: "python manage.py migrate actstream --noinput"
    leader_only: true

推荐答案

我遇到了完全相同的问题.唯一对我有用的是(自动)重建我的整个环境.您可以在 AWS 控制台中执行此操作.转到您的环境并单击操作 > 重建环境.这将需要一些时间，之后它会自动重新启动您的应用而不会出现此错误.

I had the exact same problem. The only thing that worked for me was (automatically) rebuilding my entire environment. You can do that in the AWS console. Go to your environment and click Actions > Rebuild Environment. This will take some time, afterwards it will automatically relaunch your app without this error.

更新:

问题时不时地重复出现.我发现 pip 编译 psycopg 时出了点问题，这是 postgreSQL 支持所必需的.还没有找到真正的解决方案.

The problem keeps returning so now and then. I figured out that something is going wrong when pip compiles psycopg, which is needed for postgreSQL support. Haven't found a real solution yet.
