haxelib versions

hello
everytime i reinstall ufront ( which i've just done now )  i have to erase dependencies version in the multiple haxelib.json of ufront , ufront-mvc etc ... like

  "dependencies": {
    "ufront-mvc": "",   // here 
    "ufront-orm": "1.1.0",
    "ufront-easyauth": "", //or here
    "pushstate": "2.1.0"
  }

to make it compile .
is it a bug from haxelib or ufront ?
