我正在尝试使用 SQS 将一个使用芹菜周期性任务的 django 项目部署到弹性 beanstalk 上。
我或多或少地遵循了这里的说明：
如何使用 AWS Elastic Beanstalk 可扩展的 Django 应用程序运行芹菜工人？
当我部署到 eb 时，定期任务未执行。
检查芹菜节拍日志，一切似乎都很好：

我一直在寻找答案，有些人似乎也有同样的问题。我尝试部署不同版本的芹菜和海带，但无法解决。
这是我的要求.txt文件：

如果我通过 ssh 连接到实例并键入"python -c 'import pycurl'"，一切似乎都正确，没有问题。
有人知道如何解决吗？任何帮助将不胜感激。
谢谢。
当你这样做时
python -c 'import pycurl'
确保 Python 版本与 Python 3.6 相同，可以肯定的是，请尝试：
python3.6 -m pip install pycurl
对于那些在尝试部署使用 Celery 的 Django 应用程序时试图解决以下问题的人：
"集线器"对象没有属性"_current_http_client"...
<小时 />导入错误：curl 客户端需要 pycurl 库。
我正在使用以下软件包：
- 芹菜==4.4.7
- 姜戈-芹菜节拍==2.1.0
- 姜戈-芹菜-结果==1.2.1
溶液：-
使用 Elastic Beanstalk 的配置文件安装 pycurl，请参考下面的配置文件：
packages:
yum:
gcc: []
gcc-c++: []
graphviz-devel: []
libjpeg-turbo-devel: []
libcurl-devel: []
openssl-static.x86_64: []

上述代码块中的第二个容器命令应有助于解决这些问题。
