我的目录:
我尝试将 depoly 部署到 Heroku 中的 React 项目中。
但是，它打印错误消息。
这是'错误:ENOENT:没有这样的文件或目录，打开'/app/build/index.html'
我的node.js服务器代码
服务器/app.js:
import express from 'express';
import morgan from 'morgan';
import path from 'path';
import loader from './loader';
const app = express();
// server static file
app.use(express.static(path.resolve(__dirname, '../build')));
app.use('/', loader);
// exporting module
export default app;
服务器/loader.js:
...
export default (req, res) => {
const filePath = path.resolve(__dirname, '../build', 'index.html');
fs.readFile(filePath, 'utf8', (err, htmlData)=>{
if (err) {
console.error('read error', err)
return res.status(404).end()
}
const context = {}
const markup = renderToString(
<StaticRouter location={req.url} context={context}>
<App/>
</StaticRouter>
)
if (context.url) {
redirect(301, context.url)
} else {
const Rendered = htmlData.replace('{{SSR}}', markup)
res.send(Rendered)
}
})
我认为我没有问题，但是当我尝试连接时，我得到一个“未找到”页面。
如何解决这个问题？

最佳答案
想通了。
它在我的 .gitignore 文件中有“build”。
如果是的话，build目录也会推送到github，还有其他办法吗？
