当我在Django项目中设置React时,我遇到了这个错误

模块构建中的ModuleBuildError失败(来自./node_modules/babel-loader/lib/index.js):SyntaxError:C:\ Users\1Sun\Cebula3\cebula_react\assets\js\index.js:支持实验语法'classProperties '目前尚未启用(17:9):

Add @babel/plugin-proposal-class-properties (https://git.io/vb4SL) to the 
'plugins' section of your Babel config to enable transformation.

所以,我安装了@ babel/plugin-proposal-class-properties并把它放在babelrc中

的package.json

我显然检查connect-privkey-to-provider了依赖项中是否存在模块。但是，它一直说模块'connect-privkey-to-provider'是无关的npm 并且找不到模块'connect-privkey-to-provider'

我的代码有什么问题？

我正在学习DRF，现在感到有点困惑。
我设置QuestionView并QuestionSerializer喜欢这个。

视图.py

class QuestionView(viewsets.ModelViewSet) :
    queryset = models.Question.objects.all()
    serializer_class = QuestionSerializer

    def list(self, request, *args, **kwargs):
        serializer = QuestionSerializer(models.Question.objects.all())
        return Response(serializer.data)

序列化器.py

class QuestionSerializer(serializers.ModelSerializer):
    class Meta:
        model= Question
        fields= ("question_text", "owner", "pub_date")

urls.py

router = routers.DefaultRouter()
router.register('profile', cebula_views.SettingView)
router.register('question', cebula_views.QuestionView.as_view({
    'get':'list',

}), 'userpage-question')

urlpatterns = [
    ...
    url(r'^', include(router.urls)),
    ...
] 

文件“C:\Users\1Sun\Cebula3\businessproject\urls.py”，第 34 行，在 url(r'^', include(router.urls)) 中，文件“C:\Users\1Sun\AppData\Local\ Programs\Python\Python36\lib\site-packages\rest_framework\routers.py”，第 101 行，在 url self._urls = self.get_urls() 文件“C:\Users\1Sun\AppData\Local\Programs\Python\ Python36\lib\site-packages\rest_framework\routers.py”，第 363 行，在 get_urls urls = super(DefaultRouter, self).get_urls() 文件“C:\Users\1Sun\AppData\Local\Programs\Python\Python36 \lib\site-packages\rest_framework\routers.py”，第 …

我想我遵循了其他人所说的设置“语义用户界面反应”的所有步骤，但有一个错误。

./assets/components/UserPage/UserPageQuestion/UserPageQuestion.js 模块中的错误未找到：错误：无法解析“C:\Users\1Sun\Cebula3\cebula_react\assets\components\UserPage”中的“semantic-ui-react” \UserPageQuestion'@./assets/components/UserPage/UserPageQuestion/UserPageQuestion.js 31:0-67 91:63-70 91:98-104 93:29-35 93:76-81 95:31-38 95:66 -72 98:29-35 100:42-47 @ ./assets/components/UserPage/index.js @ ./assets/components/UserPage/UserPage.js @ multi ./assets/components/UserPage/UserPage.js

                 <Image src='/images/wireframe/short-paragraph.png' />

}

有什么问题？？
