When I run yarn, I receive the following error:

yarn install v0.16.1
[1/4] Resolving packages...
[2/4] Fetching packages...
error [email protected]: The engine "node" is incompatible with this module. Expected version ">=6.0.0".
error Found incompatible module

However, the version of Node that I have installed is v6.9.2-pre, which seems to be correct for the version range. Any ideas why I get this error?

• This seems to be a tag mismatch, she is talking about facebook's yarn. So no need to close. – nils Commented Oct 24, 2016 at 19:20

After upgrading to current tag v7.0.0 and node -v v7.0.0 yarn work just fine. I think, this problem related to -pre release versions or maybe just about the prefix inside of the version output.

To upgrade node in mac

 brew upgrade node
