[LayersPlugin]: Error: Can not find yarn.lock! about serverless-layers

[agutoli]

You can not pass yarn.lock to custom:packagePath. That option is just for package.json file. If you have a project which package.json is not in the root folder for example, you can do like:

custom:
  serverless-layers:
    packagePath: ./MyCustomFolder/package.json

[agutoli]

Is that working? @mattnakatani

[mattnakatani]

yes if i point it at a package json it will be working however I was hoping to use the yarn lock since that is more indicative as to whether or not the dependencies have changed and a new layer needs to be deployed.

I was thinking yarn.lock should work because #4

[agutoli]

Yes, It has "yarn.lock" support already.

I can see here:
https://github.com/agutoli/serverless-layers/blob/master/src/package/Dependencies.js#L53

[mattnakatani]

right but it still doesn't work with my yarn lock

[agutoli]

Ok, can you share your custom settings, please?

Like:
custom:
  serverless-layers:
    packagePath: ./MyCustomFolder/package.json

[mattnakatani]

custom: serverless-layers: packageManager: yarn compatibleRuntimes: ['nodejs','nodejs10.x'] packagePath: ../yarn.lock

[agutoli]

@mattnakatani Your options is wrong.

Please try:

custom: 
  serverless-layers:
     packageManager: yarn

It should work.

[mattnakatani]

so is there no way to specify packagepath for yarnlock?

[agutoli]

Not necessary. As I said above, I already copy that file every time you do a deployment. Is that file on root folder? If yes, don't worry, it should work.

[agutoli]

Aldo, I had no usecases which It was necessary, I can implement It, but I do need to understand why.

[mattnakatani]

thank you
