Unable to build repo - @iiif-mec/core errors

[Whatapalaver]

I have just cloned the repo, installed dependencies and attempted to run the build command with yarn build

I am using the following versions:

• node v8.15.0
• lerna v3.13.4
• yarn v1.15.2

I am getting a number of errors seemingly related to @iiif-mec/core and am unable to get beyond the build stage.

lerna info version 2.11.0 lerna ERR! build Errored while running script in '@iiif-mec/core' lerna ERR! execute callback with error lerna ERR! Error: Command failed: npm run build lerna ERR! { parser: "babylon" } is deprecated; we now treat it as { parser: "babel" }. lerna ERR! npm ERR! code ELIFECYCLE lerna ERR! npm ERR! errno 1 lerna ERR! npm ERR! @iiif-mec/core@1.0.29 build: 'NODE_ENV=production fesk-build && docz build' lerna ERR! npm ERR! Exit status 1

I can give you more of the error message if it helps.

Were you running on the master branch? I think there was a React version issue there. You could try checking out the feature/performance-optimisation and trying yarn && yarn build there, as I can see some successful builds running on that branch

I was on master but I've just switched to feature/performance-optimisation but I am still getting the same error when I run yarn build.
