# create-react-app does a check on several packages to make sure the # versions required by CRA are the package versions available: # https://github.com/facebook/create-react-app/blob/dea19fdb30c2e896ed8ac75b68a612b0b92b2406/packages/react-scripts/scripts/utils/verifyPackageTree.js#L23-L29 # The repo is set up to use yarn workspaces and keeps all # packages/jaeger-ui packages local to packages/jaeger-ui. But, the # check CRA does not detect this. So, the following env-var skips the # check. SKIP_PREFLIGHT_CHECK=true
