Since both the server and the index file are INSIDE the "public" directory, you can simply use :
由于服务器和索引文件都在“公共”目录内，您可以简单地使用：
res.sendfile('./main.html');
To answer the question in the comments : In Express 4.x, the sendfilemethod was replaced by the sendFilemethod (all lowercase -> camelCase). Probably just an oversight in early versions, that got fixed in the latter.
回答评论中的问题：在 Express 4.x 中，sendfile方法被替换为sendFile方法（全部小写 -> 驼峰式）。可能只是早期版本的疏忽，在后者中得到了修复。

I had a similar issue when I referred to distfolder.
the relative path to index.html was:
当我提到dist文件夹时，我遇到了类似的问题。index.html 的相对路径是：
app.get('*', (req, res) => {
res.sendFile(path.join(__dirname, 'dist/project-name/index.html'));
});

This solution works for me:
这个解决方案对我有用：

For me using the "." in the path didn't work, instead, I tweaked it as:
对我来说使用“。” 在路径中不起作用，相反，我将其调整为：
res.sendFile(__dirname + '/public/main.html');

You missed the dot. Keep in mind relative directory is
你错过了点。请记住相对目录是
res.sendfile('./public/main.html');
回答by Guy Korland
res.sendfile('/public/main.html');
should be changed to
应该改为
res.sendfile('./public/main.html');
回答by pbhadu21
Just use this : res.sendFile(__dirname + '/main.html');It'll definitely work. :)
只需使用这个：res.sendFile(__dirname + '/main.html');它肯定会起作用。:)

server.js
const express = require('express');
const app = express();
app.use(express.static(__dirname + '/dist/projectName'));
app.post('/*', function(req, res){
res.sendFile(__dirname + '/dist/projectName/index.html');
});
app.listen(4200);

I had the same problem. After emailing heroku, mine was a case sensitivity problem. One of my files was in all caps, and i had to make adjustments from there.
我有同样的问题。在给 heroku 发电子邮件后，我的是一个区分大小写的问题。我的一个文件全部大写，我不得不从那里进行调整。

Though OP's cause is different for this error I got the same error due to a different reason so I am posting this for other's who come here.
尽管 OP 的原因因此错误而异，但由于不同的原因，我遇到了相同的错误，因此我将其发布给其他来这里的人。
I had a server-side shell script that was changing the current directory. Since we use relative paths in sendfileI started seeing this error after this script would run. This shell script was being run by Node.
我有一个正在更改当前目录的服务器端 shell 脚本。由于我们sendfile在此脚本运行后使用相对路径，因此我开始看到此错误。这个 shell 脚本是由 Node.js 运行的。
