Error when running example usage

What's going wrong

When I run sudo node test this error pops out

node:internal/modules/cjs/loader:1154
  return process.dlopen(module, path.toNamespacedPath(filename));
                 ^

Did you install node with nvm? That caused problems for me because the build tools end up pointing at the wrong things.

This fixed it for me but ymmv:

1. curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash //don't do this if nvm is already installed
2. Restart terminal so that nvm is in the path.
3. nvm install v12.22.3
4. sudo ln -s "$NVM_DIR/versions/node/$(nvm version)/bin/node" "/usr/local/bin/node"
5. sudo ln -s "$NVM_DIR/versions/node/$(nvm version)/bin/npm" "/usr/local/bin/npm"
