Rollup.js未解决的依赖关系

25

我正在尝试将rollup.js集成到项目中。目前在控制台中出现如下警告（未解决的依赖项），我不确定原因是什么，也不知道该如何解决：

'fs' is imported by node_modules\filereader\FileReader.js, but could not be resolved – treating it as an external dependency

'fs' is imported by  commonjs-external:fs, but could not be resolved – treating it as an external dependency

preferring built-in module 'punycode' over local alternative at 'C:\Users\Ryan\OneDrive\Projects\Custom Coding\Zapier\Ryan Test\node_modules\punycode\punycode.js', pass 'preferBuiltins: false' to disable this behavior or 'preferBuiltins: true' to disable this warning

preferring built-in module 'punycode' over local alternative at 'C:\Users\Ryan\OneDrive\Projects\Custom Coding\Zapier\Ryan Test\node_modules\punycode\punycode.js', pass 'preferBuiltins: false' to disable this behavior or 'preferBuiltins: true' to disable this warning

这里是test.js脚本，需要FileReader和https：

var FileReader = require('filereader');
var https = require('https');

最后是执行打包的 rollup.config.js 文件：

var rollup = require('rollup');

var commonjs = require('rollup-plugin-commonjs');
var nodeResolve = require('rollup-plugin-node-resolve');
var globals = require('rollup-plugin-node-globals');
var builtins = require('rollup-plugin-node-builtins');

// build bundle
rollup
  .rollup({
    entry: 'test.js',
    plugins: [
      nodeResolve(),
      commonjs(),
      globals(),
      builtins()
    ]
  })
  .then(bundle => bundle.write({
    dest: 'rollupBundle/bundle.js',
    format: 'cjs'
  }))
  .catch(err => console.log(err.stack));

CLI会生成更具信息性的警告——如果您更新配置文件以使用标准格式，那么您可以使用rollup -c，它通常会给您一个URL来帮助诊断问题。

这是一个带有必要更改的配置文件，以消除这些警告：

import commonjs from 'rollup-plugin-commonjs';
import nodeResolve from 'rollup-plugin-node-resolve';
import globals from 'rollup-plugin-node-globals';
import builtins from 'rollup-plugin-node-builtins';

export default {
  entry: 'test.js',
  dest: 'rollupBundle/bundle.js',
  format: 'cjs',
  external: [ 'fs' ], // tells Rollup 'I know what I'm doing here'
  plugins: [
    nodeResolve({ preferBuiltins: false }), // or `true`
    commonjs(),
    globals(),
    builtins()
  ]
};

更新：现在，“官方”的Rollup插件已经放在npm的@rollup名称空间下，如果您安装了上述两个版本，将会收到一个“npm WARN deprecated”的消息，因此请安装较新的版本：

npm install @rollup/plugin-commonjs --save-dev
npm install @rollup/plugin-node-resolve --save-dev

然后像这样使用它们：

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