起初，我在模数网站本身上发表了一篇文章，但我认为它的社区不是很活跃，所以它包含以下内容：应用程序，当我尝试加载它时，URL 会在文档：
未找到或无法收集到任何应用程序实例。
在日志中，它说这个，我真的不明白。

这一切都在一个单独的项目上以相同的方式完成，现在它不会工作。任何建议或解决方案将不胜感激！
（顺便说一句，我不确定这是否正常，但我注意到 node_modules 文件夹不在我的文件列表中，我不知道为什么，因为它在我的本地文件夹中）
但是，现在我已经到了日志会说的地方：

express deprecated res.sendfile: Use res.sendFile instead at server.js:9:6
Error: ENOENT, stat '/mnt/app/index.html'at Error (native)
Error: ENOENT, stat '/mnt/app/index.html'at Error (native)
我知道它正在 /mnt/app 中寻找文件，但我不知道为什么，当它在本地运行时，它会在公共目录中找到所有内容。
我的文件树如下所示：
Public -[
- index.css
- index.js
- index.html
Server.js
node_modules (not included in server, I guess modulus installs based on package.json dependencies)
package.json
我用这个绑定公用文件夹
app.use(express.static(path.join(__dirname, 'public')));
谁能帮我解决这个问题，或者至少找到问题。谢谢！！
