Question

我正在使用npm，coffee script和jest建立一个构建，但是我看到了神秘的错误-显然是来自babel配置。

npm运行测试

...

插件/预设文件不允许导出对象，只能导出功能。在/Users/tonyofthewoods/worktuna/temptest/node_modules/babel-preset-jest/index.js
  at createDescriptor (node_modules/@babel/core/lib/config/config-descriptors.js:178:11)
...

完整项目位于this github repo.

package.json

    "rollup-plugin-coffee-script": "^2.0.0",
    "rollup-plugin-commonjs": "^9.3.4",
    "rollup-plugin-node-resolve": "^4.2.1"
}

}

我读过线程，在打字稿中会发生类似的问题并做出反应-在这种情况下，答案是确保所有babel组件都来自babel 7的@babel命名空间。

但是package-lock.json中的babel-preset-jest是“ ^ 21.2.0”，我相信这是最新的和最大的。

如何修复npm / coffee / jest构建配置？
