WebStorm (2018.2.3) 中 Jest (23.5.0) 中未解析的函数或方法“xxx”

我最近在 Jest (23.5.0) 和 WebStorm (2018.2.3) 智能感知方面遇到了问题。对于所有 Jest 方法（例如toHaveBeenCalledWith, toHaveLength），我收到一个Unresolved function or method "xxx" error.

I have @types/jest我参与了我所有的项目，除了最近的一个项目，当我被 CRA 开除后，这个项目就停止了。 奇怪的是，如果我删除所有项目node_modules，Jest 上的智能感知工作得很好 - 但一旦我跑了yarn install智能感知停止工作，我得到了Unresolved function or method "xxx"错误。所以我怀疑我的一个包裹导致了@types/jest停止工作。

我尝试过的：

• 中讨论的所有方法JetBrains 论坛 https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000357324-Get-rid-of-Unresolved-function-method-variable-warning-in-Jest-test-files?page=1#community_comment_360000121219关于这个问题

• This 替代解决方法 https://medium.com/front-end-hacking/fix-element-is-not-imported-jest-describe-it-expect-in-webstorm-aaf8c29ae3c2

• 使Webstorm的缓存失效并重新启动

• 删除锁定文件后重新安装软件包

在网络风暴中： 偏好 |语言和框架 | JavaScript |库，按“下载...”，从可用存根列表中选择“jest”，按“下载并安装”
