learnyounode EEXIST: file already exists, mkdir 'C:\Users\Administrator\.config\workshopper'

[uvalover]

There's something wrong with file exist check on learnyounode project

• I firstly executed learnyounode, it created [learnyounode, workshopper] folders, everything goes well
  

• When I secondly executed learnyounode, it gave me the following message [EEXIST: file already exists, mkdir 'C:\Users\Administrator.config\workshopper']
  
  This check will prevent me from using this tool, but when I deleted [learnyounode, workshopper] , it will goes well.
  but it's so strange,

  Is there anyone can help me solve this problem?
