I came into this same error on Monday morning. Perhaps it was overkill, but my solution was to uninstall npm, remove the /usr/lib/node_modules/npm/node_modules/ directory, and reinstall npm. Everything appears functional now.

To be precise, this is the full error message I saw if I ran npm, like npm --version:

For what it's worth, I got this error under Arch Linux with a direct install of npm, not using nvm.
