我将我的应用程序的新版本作为zip文件上传，然后单击部署。然后状态变为严重。
这是错误跟踪：

经过多次尝试，甚至恢复到较旧的版本后，对于该环境而言，无法部署的能力始终如一。
[之后，我通过使用带有zipfile的本地docker映像隔离代码和错误消息来解决此问题。在docker之外的计算机上运行代码并没有发现任何问题，因为pip / pipenv部分缺少某些依赖关系。
本地docker测试步骤：
其中有一个Docker容器：
docker system prune
使用Dockerfile转到文件夹
docker image build -t <app_name>:<version_number> .
要在本地运行： （docker rm <app_name>首先，如果您已经从先前的测试中获得了一个停止使用的同名容器）
docker container run --publish 80:80 --name <app_name> myapp:1.0
注意： 这不会让您测试需要环境变量的AWS函数，例如〜.aws凭证，因为它们不在映像中。 （但您可以将其与Dockerfile一起添加）
一旦Docker容器运行，您将看到（我看到）在本地测试时不存在的错误消息，因为它们是由缺少软件包依赖项和pipenv错误引起的。
