Looks like this must be related to #9265.

Can you shoe the full command that fails here. You can with do this by running make VERBOSE=1 of my switching your cmake build to use ninja with -G Ninja (ninja defaults to showing the failing command when a command fails).

Actually it looks like this might be an old version of node. What version are you running? (what does /usr/bin/nodejs --version say?)

[kripken]

This does seem to be because of an older version of node. But looks like it's a regression where we added code with let in our compiler.js code. Fix in #9324

Yes, I made a mistake in my node version. Now it is ready to use, thank you.
