const keys = path.split('.');
    let node = rootNode;
    for (const key of keys) {
      const child = node.children.get(key);
      if (!child) {
        return;

  scanTreeRecursively(
    depTree,
    missingDependencies,
    satisfyingDependencies,
    key => key,
  );
  function scanTreeRecursively(node, missingPaths, satisfyingPaths, keyToPath) {
