Bug Report

After updating 6.7.0 to 6.8.0 I get the following error after requiring https://github.com/Automattic/node-canvas

Error: Module did not self-register.
    at Object.Module._extensions..node (internal/modules/cjs/loader.js:1003:18)
    at Module.load (internal/modules/cjs/loader.js:812:32)
    at Function.Module._load (internal/modules/cjs/loader.js:724:14)
    at Module.require (internal/modules/cjs/loader.js:849:19)
    at require (internal/modules/cjs/helpers.js:74:18)
    at Object.<anonymous> (c:\code\tepez\node_modules\canvas\lib\bindings.js:3:18)

This is bindings.js:3: https://github.com/Automattic/node-canvas/blob/v2.6.1/lib/bindings.js#L3

I suspect this is due to #1091
Maybe it doesn't clear the module cache correctly?

@dl748 Since you made the commit, can you please take a look?

Locking version at 6.7.0 (without changing anything else) prevents the issue

Environment

• serverless version: 1.83.0
• serverless-offline version: 6.8.0
• node.js version: 12.13.0
• OS: [e.g. macOS 10.13.4, Windows 10, Ubuntu 16.04]

Do you have a sample of how you are using it?

Minimal reproduction project at https://github.com/tomyam1/slss-offline-1112

Waths weird is that in the minimal project, serverless-offline version 6.6.0 works and versions 6.7.0 and 6.8.0 don't.
While in our real project 6.7.0 does work and 6.8.0 doesn't.

I'll need to look further, but it looks like it due to a non javascript module being unloaded.

Did you ever figure this issue out? Every change to any serverless function results with "Module did not self-register" error. It's not a fun dev env when you need to restart the server and wait a minute every time you hit save.

Thanks

Yes

Closing this becaus it's a duplicate of #871
