我配置错了吗?

推荐答案

我遇到了同样的问题，但是我需要将testEnvironment作为节点.解决方案是降级到"jest": "^24.9.0".将testEnvironment设置为node时，最新版本似乎有问题.

I had the same problem but I needed the testEnvironment to be node. The solution is to downgrade to "jest": "^24.9.0". It seems like there's a problem with the latest version when testEnvironment is set to node.

更新

此评论似乎在jest 25.2.2中已解决此问题 https://github.com/facebook/jest/issues/9538#issuecomment-604522345 我还没有测试过.
