have you found a solution? I have the same issue and installing them doesn't seem to fix the issue. - Roel Veldhuizen

I suspect you have solved this issue by now but if not the solution to the problem lie in reading the error message. For starters the 'yarn run encore dev' is complaining that some dependencies required by some of the libraries your application depend on, are missing from your installation of node.
