Are you 100% sure Node version is 5.3.0 and not some older Node?

[Evan-GK]

npm -v shows "5.3.0". I had gone down to 4.6.1 to confirm that the problem could be reproduced with npm 4.x. But updated back to 5.3.0. Getting same error with both versions.

node -v shows "v4.7.3"

Sorry, I got confused 😞

As per installation:

You’ll need to have Node >= 6 on your machine.

Node 4 or 5 won’t work. Please update to Node 6.
