I have this error, I know that the doc says to update node. My node is already at v10.15.3, and my relaXed at 0.2.1. someone can help me?

Can you symlink to the same binary or update both in some way?

Might work with su.

Ok, now my user/bin/node is at the right version, and my flux are complete. Thanks for the support!
