        if self.cleaned_data['password'] != self.cleaned_data['password1']:
    KeyError: 'password1'

forms.py:

    class RegisterForm(forms.ModelForm):
        """注册表单"""
        email = forms.EmailField(label='邮箱', min_length=3, widget=forms.EmailInput(attrs={
            'class': 'form-contrl', 'placeholder': '邮箱'}))
        password1 = forms.CharField(label='密码', min_length=6, widget=forms.PasswordInput(attrs={
            'class': 'form-contrl', 'placeholder': '密码'}))
        password2 = forms.CharField(label='再次输入密码', min_length=6, widget=forms.PasswordInput(attrs={
            'class': 'form-contrl', 'placeholder': '再次输入密码'}))

        class Meta:
            model = User
            fields = ('email', 'password1')

        def clean_email(self):
            """ 验证用户是否存在 """
            email = self.cleaned_data.get('email')
            exists = User.objects.filter(email=email).exists()
            if exists:
                raise forms.ValidationError('邮箱已经存在!')
            return email

        def clean_password1(self):
            """验证密码是否相等"""
            print(self.cleaned_data)

            if self.cleaned_data['password1'] != self.cleaned_data['password2']:
                raise forms.ValidationError('两次密码输入不一致！')
            return self.cleaned_data['password1']

     <form action="" method="post">
                                csrf_token
                                
                                <input type="submit" style="margin-top: 1em;" class="button is-link is-fullwidth" value="注 册">
    </form>

原因分析：

因为在forms.py中字段是先定义 email，password1，password2，那么forms在clean data 的时候是按照e->p1->p2，那么在定义clean_()函数时，在clean_password1()中，password2还没有clean data，所以在forms.cleaned_data中就没有password2字段。
