我在使用amchart5集成进行jest测试时遇到此错误。

Details:

    C:\Users\BASHIMX5\Projects\Bitbucket\hf-ui\node_modules\@amcharts\amcharts5\index.js:1

嘲弄：

node_modules/
__mocks__/
├─ @amcharts/
│  ├─ amcharts5/
│  │  ├─ themes/
│  │  │  ├─ Animated.js
│  │  ├─ index.js
│  │  ├─ xy.js

但是得到上面的错误。有什么帮助吗？我花了另外24小时来修复。但是没有运气。我正在运行nx worksapce。
