Looks like it's because I was still using VS's embedded node version (which was ancient). Fixed by moving the tools path to the bottom:

Not sure if an obsolete version of Node was also part of the problem, but what Shawn Wildermuth suggested worked (after updating Node) - moved the option $(VSINSTALLDIR)\Web\External to the bottom. Thanks Shawn!

Moved the option $(VSINSTALLDIR)\Web\External to the bottom works for me without update Node. Thanks Shawn!
