问题已解决，"rollup-plugin-babel": "^4.0.3",此版本问题，执行npm install --save-dev rollup-plugin-babel@3即可

我的也报错按照你的配置文件来就可以了

{
  "name": "rollup-cj",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "rollup -c rollup.config.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-core": "^6.26.3",
    "babel-plugin-external-helpers": "^6.22.0",
    "babel-preset-latest": "^6.24.1",
    "rollup": "^0.66.6",

运行 npm install --save-dev babel-core 试一下

找到原因了，rollup-plugin-babel默认版本为4，使用以下版本就ok了 { "name": "rollup-cj", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "start": "rollup -c rollup.config.js", "test": "echo \"Error: no test specified\" && exit 1" }, "author": "", "license": "ISC", "devDependencies": { "babel-core": "^6.26.3", "babel-plugin-external-helpers": "^6.22.0", "babel-preset-latest": "^6.24.1", "rollup": "^0.66.6", "rollup-plugin-babel": "^3.0.7", "rollup-plugin-node-resolve": "^3.4.0" } }
