I just updated my development docker image to the latest Node.js version (14.15.1), blew away all “node_modules” folders on all levels and the same with the “package-lock.json” files. Then did run lerna bootstrap --hoist. After that, everything was running perfectly.
So the answer is “no”. All should be running just fine.
Not sure if you upgraded from v12 to v14 keeping all the “node_modules” in place. Because that will cause problems for sure. After all, would you then run code that got generated by version 12 for v12 with v14.
