我应该修改什么使其工作？应用程序组件正在您的
index.jsReactDOM.render（，document.getElementById（'root'）
尝试注释或删除上面的行，看看是否有帮助。
更好的方法是，将App（）组件修改为所需内容，而不是直接修改公用文件夹中的html文件。您正在使用id根节点呈现应用程序。加载页面时，您会看到登录表单，但一旦加载javascript，根目录中的内容就会被react内容替换。我不确定你想用这个实现什么。我不完全确定我是否正确理解了你的问题，但据我所知，你根本没有导入public/index.html文件
index.js文件导入App.js，结果就是App.js文件的内容。
如果这确实是您要问的问题，您可以要求将HTML文件转换为变量，将其字符串化（例如使用）在div中使用危险的lySetinerHTML道具来显示有冲突的内容。我不确定我是否正确回答了你的问题，但我认为你应该先返回或呈现你的html，然后将其插入函数App（）{}
。即使是默认的html页面？你如何呈现你的App（）
？我想问题不是很清楚。@EmWai我已经更新了这个问题，我认为这与你公用文件夹中的html无关。您的src/
文件夹中是否有类似index.js的文件？有可能应用程序组件正在那里运行…对于css和js文件，请检查文件的路径。编译后显示
，编码时显示“
%PUBLIC\u URL%/
是公用文件夹的前缀。所以%PUBLIC\u URL%/css/vendors.min.css
实际上是PUBLIC/css/vendors.min.css
看看你的文件是否放在正确的位置上工作得很好：）如果你认为这个问题是有效的，请向上投票我是新来回复的，我试图显示管理员登录页面而不是默认的回复页面。但是无法显示它，在对index.js中的行进行注释后，它工作了，但是css和js没有加载
