https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=39151 --- Comment #3 from Jonathan Druart <jonathan.druart@gmail.com> --- I have found https://github.com/yarnpkg/yarn/issues/7568 That points to https://stackoverflow.com/questions/41789887/dont-understand-yarn-check-warn... Which suggests to remove yarn.lock and try again. It works (ie. yarn check does not show the "dedupe" warnings) but the yarn install show other warnings: root@kohadevbox:koha$ yarn install --modules-folder /kohadevbox/node_modules yarn install v1.22.22 info No lockfile found.
