move, remove generate erors or silent failed

`var github = new window.github_api({
    username: "aplib",
    password: "xxx",
    auth: "basic"
});
var repo = github.getRepo('aplib', 'tmp');
repo.remove('gh-pages', '1/1.dat', function(err) {
    if (err) console.log(err);
});`

it's not worked. no error messages, no remove file.
in repo only folder '1' and file '1/1.dat'.
