node fs.readFileSync读取文件报找不到路径

如图,server.js想读取public下的index.html文件,却报错。不太清楚是哪里出错了。代码在最下边

Error: ENOENT: no such file or directory, open '\public\index.html'

import express from 'express'
import routes from '../routes'
import serverRender from './render'
import fs from "fs";
import path from "path";
const app = express()
const template = fs.readFileSync(path.resolve(__dirname,"../public/index.html"),"utf8")
console.log(template);
app.use(express.static('public'))
app.get("*", (req, res) => {
  res.send(serverRender(req, routes))
})

app.listen(3000, () => {
  console.log('server listening on port 3000')
})

    我是这样解决的。process.cwd(): 总是返回运行 node 命令时所在的文件夹的绝对路径。看这个文章摸索出的解决办法:

      const template = fs.readFileSync(process.cwd() + '/public/static/index.html', 'utf8')

      path.join(__dirname,"../public/index.html")

        windows 系统
        mac 系统下面,路径是对的哦
