Quiero separar el directorio de rutas, pero no puedo y obtengo el siguiente error.

 rror [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './cjs' is not defined by "exports" in /mnt/.../projects/.../nanoexpress/node_modules/nanoexpress/package.json

aplicación.js

 const nanoexpress = require('nanoexpress'); var indexRouter = require('./routes/index'); const app = nanoexpress(); const port = 3333; app.get('/', (req, res) => { res.send('Hello World!') }) app.use('/testy',indexRouter) app.listen(port)

enrutadores/inde.js

 const nanoexpress = require('nanoexpress/cjs'); const Route = require('nanoexpress/cjs/Route'); const app = nanoexpress(); const testRoute = new Route(); testRoute.get('/route', async () => 'hello'); module.exports.testRoute = testRoute;
