问题
I'm running sls deploy and getting the following warning that spams many lines.
Serverless: WARNING: Could not determine version of module babel-runtime
Serverless: WARNING: Could not determine version of module babel-runtime
Serverless: WARNING: Could not determine version of module babel-runtime
Serverless: WARNING: Could not determine version of module babel-runtime
Serverless: WARNING: Could not determine version of module babel-runtime
...
What is the cause of this warning, should I be concerned? How do I fix it?
(If I need to add extra information to this question, please let me know and I'll edit the question right away).

I'm having the same issue in the following scenario:
Serverless + Webpack + Babel
In recommended webpack config, dev-dependencies are excluded. Babel-runtime (depends of babel, normally added as dev-dependency) is a dev-dependency too.
If you add babel-runtime to your common dependecies, now serverless (using webpack) will package babel-runtime with full information about the package (in this case, the version required).
yarn add babel-runtime
or
npm i babel-runtime
You can avoid these warnings.
