`harp init` doesn't work

After installing harp by their tutorial I can't create default template from the second tutorial. On running harp init anyname I get

fs.js:924
  return binding.readdir(pathModule.toNamespacedPath(path), options.encoding);
                 ^

Error: ENOENT: no such file or directory, scandir '/Users/vladyslavzavalykhatko/.nvm/versions/node/v9.5.0/lib/node_modules/harp/node_modules/node-sass/vendor'

What is the issue?

Solution

Typical error assembling packages, without proper checking for dependencies that are being used.

In this case, node-sass is used somewhere, while the package isn't referenced as a direct dependency.

You should raise it as an issue against the main package, and in the meantime you can work-around the issue by installing node-sass globally:

$ npm i -g node-sass

And sometimes it can be either a permission issue, or you simply need to do a clean install. Check out this issue for details.
