错误

Question

我正在关注AWS Elastic Beanstalk的Flask tutorial来部署示例应用程序。

虽然我收到错误您的requirements.txt无效 - 完整如下。虽然我没有为我提供有用的解决方案，但我google出现此错误。

我的 requirements.txt 文件粘贴在以下部分中。我正在使用 Ubuntu Desktop 16.04

您可以按照本教程继续部署，但请分享。谢谢。

我在本地测试并能够复制您的问题。为了获得有关实例出错的更多信息，我使用eb logs来查看当前EC2实例上的日志。从那以后，我能够在eb-activity.log

中看到完整的堆栈

 Collecting pkg-resources==0.0.0 (from -r /opt/python/ondeck/app/requirements.txt (line 4))
    Could not find a version that satisfies the requirement pkg-resources==0.0.0 (from -r /opt/python/ondeck/app/requirements.txt (line 4)) (from versions: )
  No matching distribution found for pkg-resources==0.0.0 (from -r /opt/python/ondeck/app/requirements.txt (line 4))

我不确定pkg-resources=0.0.0来自哪里，但它不是pip中的有效包。我能够删除该行并成功部署。

您可能需要验证pip freeze的输出，并查看该库是否确实存在。
