npm test failing on v2 branch

[zanedev]

Using gatsby 2 and the gatsby 2 branch and getting the following when running npm test, not sure what the actual error is. Seems like deprecation warnings only.

$ npm test

@zanedev,

Good catch. That actually looks like an issue caused from upgrading eslint to v5.x. For now I went ahead an downgraded eslint back to v4.19.1 on my v2 branch. Just a note that this branch is still a work in progress so let me know if you notice any other issues or weird behavior since Gatsby v2 is still in beta.

@brandonkal - Since you created eslint-config-gatsby-standard you may want to look into supporting eslint v5. I can log a separate issue on your repo.

[ryanwiemer]

Closing this issue for now since it was resolved by downgrading eslint to v4.x. I can revisit this again once eslint-config-gatsby-standard supports eslint v5.x

[zanedev]

Thanks I will let you know if I come across anything else!

Unfortunately downgrading eslint didn't seem to fix it for me though I still get the same error. I removed my node_modules directory and reinstalled but same issue. Definitely have the v4.x eslint installed but same thing.

@zanedev, Hmmm weird.

I can't seem to replicate the issue after downgrading eslint. Definitely get rid of the node_modules folder. Maybe your package-lock.json is causing an issue. And if all else fails delete your .cache folder too for good measure.
