rollup打包出错（Could not resolve）

Question

Error: Could not resolve './foo.js' from src/index.ts.

// index.ts
import foo from './foo'
export default function () {
  console.log(foo)
}

// foo.ts
export default 'hello world!'

// rollup.config.js
import resolve from '@rollup/plugin-node-resolve'
import babel from '@rollup/plugin-babel'
import commonjs from '@rollup/plugin-commonjs'
export default {
    input: 'src/index.ts',
    output: {
      file: 'dist/index.js',
      format: 'umd',
      name: 'Demo'
    },
    plugins: [
      resolve(),
      commonjs(),
      babel({
        babelHelpers: 'bundled',
        exclude: 'node_modules/**',
        extensions: ['.ts', '.js'],
        presets: [
          '@babel/preset-env',
          '@babel/preset-typescript'
        ]
      })
    ]
 }

Answer 1

input: 'src/index.ts',这里路径好像有问题,src前面要加".",应该是input: '.src/index.ts'

Answer 2

plugin-node-resolve 引入方式错了

import resolve from '@rollup/plugin-node-resolve'

=>

import { resolve } from '@rollup/plugin-node-resolve'

Answer 3
