Access denied for user xxx@'localhost' (using password: YES)

I connncet to my MySQL,but my sever is denied localhost to login by once at the same time,so it's a issues to code in mysql.js:47.
Here dbConfig.host can't value from my dbConfig.So it causes throw the issue of Access denied for user xxx@'localhost' (using password: YES) when I use it to conncet.
