问题描述
我已将create-react-app部署到Azure，该create-react-app具有用于动态生成meta tags的server.js文件。
该堆栈是Linux上的节点16
在我的启动命令中，pm2 start /home/site/wwwroot/server.js --no-daemon
我的server.js如下
const express = require("express");
const path = require("path");
const fs = require("fs");
const PORT = process.env.PORT || 5000;
const app = express();
app.get("/", (req, res) => {
const filePath = path.resolve(__dirname, "index.html");
fs.readFile(filePath, "utf8", (err, data) => {
if (err) {
return console.log(err);
}
data = data.replace(/__META_OG_TITLE__/g, "Home Page").replace(/__META_DESCRIPTION__/g, "Home page description.");
res.send(data);
});
});
app.get("/snp/list", (req, res) => {
const filePath = path.resolve(__dirname, "index.html");
fs.readFile(filePath, "utf8", (err, data) => {
if (err) {
return console.log(err);
}
data = data.replace(/__META_OG_TITLE__/g, "SNP List").replace(/__META_DESCRIPTION__/g, "SNP List description.");
res.send(data);
});
});
app.get("/snp/detail", (req, res) => {
const filePath = path.resolve(__dirname, "index.html");
fs.readFile(filePath, "utf8", (err, data) => {
if (err) {
return console.log(err);
}
data = data.replace(/__META_OG_TITLE__/g, "SNP Detail").replace(/__META_DESCRIPTION__/g, "SNP detail description.");
res.send(data);
});
});
app.use(express.static(path.resolve(__dirname)));
app.listen(PORT, () => {
console.log(`Server is listening on port ${PORT}`);
});
这server.js是index.html的同级。
我收到Cannot find module 'express'错误，这是我的错误日志转储

如果我将启动命令切换为pm2 serve /home/site/wwwroot --no-daemon --spa，则一切正常。
并且，如果我在本地从Build文件夹发出node server.js，那么它在http://localhost:5000/
我花了一整天试图找出可能出了什么问题，任何帮助都将不胜感激。

目前，我只是将构建文件夹中的所有文件通过ftp传输到site/wwwroot。我目前并不担心设置CI/CD链，因为我首先希望应用程序运行。
