Passport.js错误未知的身份验证策略“本地”

Question

我也在代码中使用护照方法，例如在控制器中注册我使用req.login（）。它运作良好 - 用户创建没有错误。但是当我尝试使用此用户的用户名和密码登录时，我会打电话给护照并收到错误。

路由器：

router.post('/login', passport.authenticate('local', { successRedirect: '/',
                                                    failureRedirect: '/login',
                                                    failureFlash: true }));

终端错误：
