Django身份验证框架的授权问题

Question

我想使用Django身份验证框架构建身份验证系统。但是我从登录和注销中得到了2个不同的错误，这些错误附在下面。 Django版本：2.1.4

切换到帐户/登录/时：

TypeError at /account/login/
   login() missing 1 required positional argument: 'user'

切换到帐户/注销/时：

ValueError at /account/logout/
   The view django.contrib.auth.logout didn't return an HttpResponse object. It returned None instead.

某些代码： Views.py

def user_login(request):
    if request.method == "POST":
        form = LoginForm(request.POST)
        if form.is_valid():
            cd = form.cleaned_data
            user = authenticate(username=cd['username'], password=cd['password'])
            if user is not None:
                if user.is_active:
                    login(request, user)
                    return HttpResponse('Authenticated successfully')
                else:
                    return HttpResponse('Disabled account')
            else:
                return HttpResponse('Invalid login')
        else:
            return HttpResponse('Form is not valid')
    else:
        form = LoginForm()
    return render(request, 'account/log-in.html', {'form': form})
