rollup在创建node项目时候官网的说明是默认babel6 ，npm默认安装babel则是7+
这里初始化配置修改如下 package.json
{ "name": "bd_log", "version": "1.0.0", "description": "改版", "main": "dist/bd_log.umd.js", "src": "src/index.js", "scripts": { "build": "npm run clean && npm run lib && rollup --config build/rollup.prod.conf.js", "start": "npm run dev", "clean": "rimraf dist/** lib/**", "dev": "rollup --config build/rollup.dev.conf.js -w && livereload ‘dist/‘", "test": "jest --config ./jest.conf.js --coverage" }, "repository": { "type": "git", "url": "git@139.9.6.199:lbq/bd_welllog_rollup.git" }, "author": "lbq", "license": "ISC", "dependencies": { "@babel/polyfill": "^7.8.7", "zrender": "^4.3.0" }, "devDependencies": { "@babel/cli": "^7.8.4", "@babel/core": "^7.9.6", "@babel/plugin-external-helpers": "^7.8.3", "@babel/preset-env": "^7.9.6", "rollup": "^2.7.5", "rollup-plugin-babel": "^4.4.0", "rollup-plugin-commonjs": "^10.1.0", "rollup-plugin-json": "^4.0.0", "rollup-plugin-livereload": "^1.3.0", "rollup-plugin-node-resolve": "^5.2.0", "rollup-plugin-serve": "^1.0.1" } }
rollup配置代码如下
import json from ‘rollup-plugin-json‘
import resolve from ‘rollup-plugin-node-resolve‘
import babel from ‘rollup-plugin-babel‘
import commonjs from ‘rollup-plugin-commonjs‘
// import { eslint } from ‘rollup-plugin-eslint‘
import pkg from ‘../package.json‘
// 压缩代码
// import uglify from ‘rollup-plugin-uglify‘;
export default {
input: pkg.src,
output: {
file: pkg.main,
format: ‘umd‘,
name: ‘EUtils‘,
sourcemap: true,
},
watch: {
include: ‘src/**‘,
},
plugins: [
resolve(),
commonjs(),
json(),
// eslint({
// include: ‘src/**‘,
// exclude: [‘node_modules/**‘, ‘dist/**‘],
// }),
babel({
babelrc: false,
presets: [[‘@babel/env‘, { modules: false, loose: true }]],
include: [‘src/**‘, ‘test/**‘],
plugins: [‘@babel/plugin-external-helpers‘],
externalHelpers: true
}),
],
}
