lineReader.eachLine(...).then is not a function

When i try to use this code sample…

var lineReader = require('line-reader');

// read all lines:
lineReader.eachLine('file.txt', function(line) {
  console.log(line);
}).then(function (err) {
  if (err) throw err;
  console.log("I'm done!!");
});

… i get this error:

}).then(function (err) { ^ TypeError: lineReader.eachLine(…).then is not a function

Do you have any idea why?

Same here… Will try to find a workaround. EDIT: solved it this way:

return new Promise((resolve, reject) => {
    lineReader.eachLine(file, function lineOperation (line, last, cb) {
      doYourThing(line, cb);
    }, function finished (err) {
      if (err) return reject(err);
      resolve();
    });
  });
