Can you please explain a little more about your situation:

Is this when creating a new project?
After installing a package?
After a Meteor update?

I was attempting to run reaction commerce locally on windows, which requires meteor. After following the installation guide I ran reaction and got this error. Then I tried moving to a separate directory and running meteor create, with the same outcome.

This was a fresh install of meteor, I’ve not updated it. I installed it via choco.

I’ve not installed any packeages.

Looks like there’s a very similar issue from November:

Which was caused by some globally installed packages conflicting with Meteor’s. Do you have a node_modules folder in your user directory? (` /users/%USERNAME%/node_modules)

If so, does renaming it allow you to run meteor commands?
