webpack 新手，尝试运行我自己的服务器 (node server.js)，但我收到此消息:
$ node server.js
/path/to/server.js:3
import path from 'path'
^^^^^^
SyntaxError: Unexpected token import

我的 server.js:
require("babel-register");
import path from 'path'
import Express from 'express'
import React from 'react'
import { createStore } from 'redux'
import { Provider } from 'react-redux'
import counterApp from './reducers'
import App from './containers/App'
import { renderToString } from 'react-dom/server'
const app = Express()
const port = 3000
// This is fired every time a request is made
app.use(handleRender)
function handleRender(req, res) {
// Create a new Redux store instance
const store = createStore(counterApp) // this is taken from './reducers'
// Render the component to a string
const html = renderToString(
<Provider store={store}> // Needs an import?
<App /> // this is defined in './containers/...'
</Provider>
)
// Grab the initial state from our Redux store
const preloadedState = store.getState()
// Send the rendered page back to the client
res.send(renderFullPage(html, preloadedState))
}
// Yet to be defined...
function renderFullPage(html, preloadedState) {
return
<!doctype html>
<html>
<head>
<title>Paulos3000 Redux Universal Example</title>
</head>
<body>
<div id='root'>${html}</div>
<script>
window.__PRELOADED_STATE__ = ${JSON.stringify(preloadedState)}
</script>
<script src='/static/bundle.js'></script>
</body>
</html>
}
app.listen(port)
有人能看出我的代码有问题吗？如果您需要我提供更多信息，请告诉我(不确定具体要包括什么，因为我不知道问题的根源)。
更新:
SyntaxError: /path/to/server.js: Unexpected token (25:6)

最佳答案
根据您的 Node 版本，它不支持 import 语法。
尝试通过 require() 使用导入:
const path = require('path').default
