推荐答案

我在本地进行了测试，能够复制您的问题.为了获得有关实例出了什么问题的更多信息，我使用了 eb日志来查看EC2实例上当前的日志.由此，我可以在 eb-activity.log

I tested locally and was able to replicate your problem. To get more information about what went wrong on instance I used eb logs to view the logs currently on the EC2 instances. From that I was able to see the full stack in the eb-activity.log

 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 的来源，但它不是pip中的有效软件包.我能够删除该行并成功部署.

I'm not sure where the pkg-resources=0.0.0 came from but it's not a valid package in pip. I was able to delete that line and deploy successfully.

您可能想验证 pip Frozen 的输出，并查看该库是否确实存在.

You may want to verify the output of your pip freeze and see if that library is actually there.
