Passport.js github策略回調總是返回“TypeError：無法設置未定義的屬性'用戶'”

Question

我一般是護照身份驗證的新手，我正在嘗試使用github策略passport-github創建一個簡單的Express應用程序。 我已經成功地使用下面相同的代碼用於谷歌和推特策略，但每次我嘗試合並github策略時，每當我點擊回調路線時，我得到500響應此錯誤：

無法設置undefined的屬性'user'

TypeError: Cannot set property 'user' of undefined

我的app.js如下：

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var passport = require('passport');
var session = require('express-session');

var routes = require('./routes/index');
var users = require('./routes/users');
var auth = require('./routes/auth');


var app = express();

var GithubStrategy = require('passport-github').Strategy;

passport.use(new GithubStrategy({
  clientID: process.env.GITHUB_CLIENT_ID,
  clientSecret: process.env.GITHUB_CLIENT_SECRET,
  callbackURL: 'http://localhost:3000/auth/github/callback'
}, function(accessToken, refreshToken, profile, done) {
  process.nextTick(function() {
    done(null, profile);
  });
}));

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');

// uncomment after placing your favicon in /public
//app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use(session({
  secret: 'wordswordswords'
}));

app.use(passport.initialize());
app.use(passport.session());

passport.serializeUser(function(user, done) {
  done(null, user.id);
});

passport.deserializeUser(function(user, done) {
  done(null, user);
});

app.use('/', routes);
app.use('/users', users);
app.use('/auth', auth);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// error handlers

// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
  app.use(function(err, req, res, next) {
    res.status(err.status || 500);
    res.render('error', {
      message: err.message,
      error: err
    });
  });
}

// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
  res.status(err.status || 500);
  res.render('error', {
    message: err.message,
    error: {}
  });
});


module.exports = app;

我的/routes/auth.js：

var express = require('express');
var passport = require('passport');
var router = express.Router();


router.route('/github/callback')
  .get(passport.authenticate('github', {
    failureRedirect: '/error'
}), function(req, res) {
  res.redirect('/users');
});

router.route('/github')
  .get(passport.authenticate('github'));

module.exports = router;

在之前的項目中，我在同一個應用程序中同時實現了google和twitter策略，但是當我嘗試添加passport-github時，它打破了所有三個策略，給了我完全相同的“無法設置屬性'用戶'未定義”錯誤每當我點擊三條回調路線中的任何一條。

任何幫助將不勝感激！

這看起來像兼容性問題，快速修復設置護照版本：

"passport": "0.2.2"

長期修復可能涉及更多工作：更新代碼以使其適用於最新版本，和/或在倉庫中創建問題，或者發送帶有修復的PR（如果可以在此部分向后兼容地向lib添加）。

我們如何猜到這是問題？：當沒有與認證相關的更改+ packages.json中的stacktrace +“latest”時，測試開始失敗
