Answer

This is a good post of how to build a lambda layer..
The main thing is that your libraries in the ZIP file need to be in the correct folder structure otherwise it will not import them

The correct folder structure for libraries/modules are here:-
https://docs.aws.amazon.com/lambda/latest/dg/packaging-layers.html#packaging-layers-paths

**Example file structure for the Python Pillow library**

```
pillow.zip
│ python/PIL
└ python/Pillow-5.3.0.dist-info
```
