问题描述
我用create-react-app创建了一个小型网站。然后我意识到SEO的糟糕性，所以我决定迁移到Razzle，这应该是创建服务器端React应用程序的简单方法。
我成功迁移了机器上的所有内容，但是当我尝试在Heroku上进行部署时，出现了一个错误（远程：sh：1：razzle：未找到）
我应该补充说我已经安装了快递服务器。
所以基本上树形结构是这样的：
MYAPP
-clientside
-build
-node_modules
-public
index.html
-src
app.js
app.css
...
package.json
-models
-node_modules
-public
-views
app.js
db.js
package.json
根文件夹中的package.json看起来像这样：
{
"name": "workspace","version": "1.0.0","description": "","main": "index.js","scripts": {
"test": "echo \"Error: no test specified\" && exit 1","start": "node db.js","heroku-postbuild": "cd clientside && npm install && npm run build"
},"author": "","license": "ISC","dependencies": {
"amazon-product-api": "^0.4.4","body-parser": "^1.19.0","compression": "^1.7.4","dotenv": "^8.2.0","ejs": "^2.7.1","express": "^4.17.1","express-session": "^1.16.2","jquery": "^3.5.1","mongodb": "^3.6.2","mongoose": "^5.7.1","passport": "^0.4.0","passport-facebook": "^3.0.0","passport-local": "^1.0.0","passport-local-mongoose": "^5.0.1","prerender-node": "^3.2.5","react-router-dom": "^5.2.0"
}
}
和客户端文件夹中的package.json：
{
"name": "my-razzle-app","license": "MIT","scripts": {
"start": "razzle start --type=spa","build": "razzle build --type=spa","test": "razzle test --env=jsdom","start:prod": "serve -s build/public"
},"dependencies": {
"@material-ui/core": "^4.11.0","bootstrap": "^4.5.3","express": "4.17.1","history": "^5.0.0","query-string": "^6.13.6","razzle-heroku": "^3.0.0","react": "16.14.0","react-bootstrap": "^1.4.0","react-dom": "16.14.0","react-ga": "^3.2.0","react-helmet": "^6.1.0","react-router-dom": "5.2.0"
},"devDependencies": {
"razzle": "3.3.7"
}
}
app.js：
const express = require('express');
const path = require('path');
const app = express();
const db = require('./db');
const bodyParser = require('body-parser');
const { json } = require('body-parser');
const passport = require('passport');
const session = require('express-session');
const ObjectId = require('mongodb').ObjectID;
const fs = require('fs');
const expressSession = require('express-session')({
secret: 'secret code name',resave: false,saveUninitialized: false
});
// Serve the static files from the React app
app.use(require('prerender-node'));
app.use(express.static(path.join(__dirname,'clientside/build')));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(expressSession);
app.use(passport.initialize());
app.use(passport.session());
// some routes and API here
app.get("/edit",(req,res) => {
res.send("edit page")
})
app.get('*',res) => {
res.sendFile(path.join(__dirname + '/clientside/build/index.html'));
});
module.exports = app;
当我尝试部署该应用程序时出现错误：

我真的不知道这是怎么回事。如果我没有在“ heroku-postbuild”中放置“ && npm run build”，则在尝试部署时没有错误，但是我的页面上没有“找不到”（我只能访问/ edit页面）
有人可以告诉我我在做什么错吗？
非常感谢！
