I am using the latest version of n8n and just get 2 warnings during the build.
I already saw the post you linked in but i was not able to find a Solution.
Is it a new install or updating an existing one? It looks like the migration is failing because the table exists in the sqlite database so I suspect it was started and maybe closed before it could finish, Looking at the code it could be that a really ugly fix might be to change the SQL here: n8n/1617213344594-CreateTagEntity.ts at 7365309346ae805293d349fe006d3898eba138de · n8n-io/n8n · GitHub and add in an if not exists but that could cause other issues.
If it is a first run it might be worth just deleting the database and starting again.
