问题
I am trying to deploy my Flask app using the EB CLI following this official AWS tutorial. I receive the error 'Create environment operation is complete, but with errors'. Observing the environment logs, the server seems to be lacking the correct Python version.
Below are the EB environment details, my PipFile, the EB CLI output and the error in the deploy logs.
How can I fix this problem?

You can specify specific versions of Python with:
$ pipenv --python path/to/python
回答1:
Based on the comments, the issue was that the EB uses Python 3.7.6, while the OP's dependencies required version 3.7.0.
The solution was to change the dependency to Python 3.7.6.
The current python version running on EB can be found here:
64bit Amazon Linux 2 v3.0.1 running Python 3.7 - Python 3.7.6
