javascript - koa's path problem when rendering?

Question

The above is the directory structure, and the routing is as follows:

const router = require('koa-router')();
const views = require('koa-views');

router.use(views(__dirname + '/views'));
router.get('/', async (ctx, next) => {
    await ctx.render('index');
});

module.exports = router;

When running the above, the following error will be reported:

So I changed the sentence about the path to

router.use(views(__dirname + '../views'));

The error message becomes

It’s very helpless. It can run after changing it to this:

router.use(views(__dirname + '/../views'));

It is normal now, but this is obviously unreasonable. How should I change it?

Post the code of index.js conveniently:

const Koa = require('koa');
const router = require('./routes/routes');

const app = new Koa();

// log request URL:
app.use(async (ctx, next) => {
    console.log(`Process ${ctx.request.method} ${ctx.request.url}...`);
    await next();
});

// add router middleware:
app.use(router.routes());

app.listen(3000);
console.log('app started at port 3000...');

Thanks!

Your routes.js file is in the /Users/dark/Works/drip-file/routes folder, so the value of __dirname is /Users/dark/Works/drip-file/routes , __dirname + '/views' is equal to /Users/dark/Works/drip-file/routes/views, so when accessing the index file, it will search under this folder, so it was not found.

When you change it to __dirname+'/../views', you will search in the folder /Users/dark/Works/drip-file/views, so you can find it.
If you want to change it to __dirname+'/views', if there is no need to create a separate routes folder, just put the routes.js file into the same folder as the index.js file.
