  • When running yarn locally it works

    When running npm install it works

    When running yarn install Dockerfile (docker build .) it fails with: error Couldn't find a package.json file in "/root/.cache/yarn/npm-readable-stream-2.2.2-a9e6fec3c7dda85f8bb1b3ba7028604556fc825e"

    I have absolutely no idea why.

    Yarn is installed this way in the Dockerfile

    ENV PATH /root/.yarn/bin:$PATH
