eb create error: FileMagic version

When I run the `eb create` command specified in [this blog post](https://aws.amazon.com/blogs/devops/using-locust-on-aws-elastic-beanstalk-for-distributed-load-generation-and-testing/), Elastic Beanstalk throws this error:

```
Application deployment failed at 2019-10-30T07:09:40Z with exit status 1 and error: Hook /opt/elasticbeanstalk/hooks/appdeploy/pre/01_configure_application.sh failed.

Executing: /usr/bin/unzip -o -d /var/app/staging /opt/elasticbeanstalk/deploy/appsource/source_bundle
FileMagic v0.7.1: compiled magic version [5.21] does not match with shared library magic version [5.34]
Archive: /opt/elasticbeanstalk/deploy/appsource/source_bundle
```

It [sounds like](https://unix.stackexchange.com/questions/460284/file-compiled-magic-version-534-does-not-match-with-shared-library-magic-vers) it's an issue with a recent version of FileMagic, but I'm afraid that I'm not familiar enough with Ruby or python to know exactly what's wrong. Any tips?

Start by reproducing the `eb create` command from the linked AWS blog post and inspect the Elastic Beanstalk deployment hook output, especially the `unzip` and FileMagic version mismatch. Done means the sample deploys successfully without the reported `01_configure_application.sh` failure.
