koa2 - node.js koa ctx=> 報錯
剛開始接觸koa 一直提示ctx=> 這個>報錯無法運行實在弄不清了也找不到資料求大神幫忙
這是報錯
app.use(ctx => {
^SyntaxError: Unexpected token >
#at exports.runInThisContext (vm.js:69:16)
at Module._compile (module.js:432:25)
at Object.Module._extensions..js (module.js:467:10)
at Module.load (module.js:349:32)

at Function.Module.runMain (module.js:490:10)
at startup (node.js:124:16)
at node.js:803:3
這是原始碼
const Koa = require('koa');
const app = new Koa();
app.use(ctx => {
ctx.body = 'Hello Koa';
});
app.listen(3000);
console.log('app started at port 3000....');
