python - 我的联系页面在 heroku 上显示错误“没有名为“'django”的模块”，但它在我的本地计算机上工作正常

Question

我可以从本地计算机向我的电子邮件发送一条消息，但是当我在 heroku 上部署我的应用程序时，我收到一条错误消息“没有名为“'django”的模块'。可能是什么问题？

视图.py

@login_required(login_url='/accounts/login/')
def s_contact(request):
    c_form = ContactForm
    if request.method == 'POST':
        c_form = ContactForm(data=request.POST)
        if c_form.is_valid():
            email = c_form.cleaned_data['email']
            subject = c_form.cleaned_data['subject']
            message = c_form.cleaned_data['message']   
            send_email(email, subject,message, ['[e-mail]'])
            messages.success(request, f'Your message has been sent!')
            return redirect(seller_home)
    else: 
        email = request.POST.get('email')
        subject = request.POST.get('subject')
        message = request.POST.get('message')

    context = {
        'c_form': c_form
    } 
    return render(request, 'seller/contact.html', context)

表格.py

class ContactForm(forms.Form):
    email = forms.EmailField(label='Your Email')
    subject = forms.CharField(required=True, max_length=150)
    message = forms.CharField(widget=forms.Textarea, required=True)

这是按要求返回的跟踪，希望对您有所帮助
