我正在尝试使用npm run test在我的环境中运行README脚本（也可以在https://github.com/acvetkov/sinon-chrome/blob/master/examples/navigate.test.js中显示）下的测试，但是遇到一个奇怪的错误。
首先：我已将Chrome的导入行更改为使用lib（而不是示例中的..src文件夹）
myProject\extension\test\affiliates.test.js:1
(function (exports, require, module, __filename, __dirname) { import chrome from 'sinon-chrome/extensions'
^^^^^^

我已经安装了mocha和sinon-chrome，这是我在package.json中的测试脚本：
"main": "Gruntfile.js",
"scripts": {
"test": "mocha"
},
您可以看到我的项目也使用grunt，所以我在想这是否可能是此错误的根源。
有人对此有任何线索吗？
