I'm trying to run some tests with Jest but I keep getting an error. It's something to do with a TypeScript config file, I already searched but didn't find much. I'm using NodeJS, TypeORM with TypeScript.
I'm getting this error when running yarn test
:
Error: Jest: Failed to parse the TypeScript config file

删除
ts-node
,改为安装ts-node-dev
。这对我很有效!sz81bmfz2#
我也遇到了同样的错误,尝试用Angular和Typescript在jest中运行测试。我的问题通过重新安装jest得到了解决:npm安装--保存开发jest
然后,这显示了我的设置存在一个潜在的配置问题--但至少我没有看到失败的错误。

检查
babel.config.js
文件是否在项目的**root /**文件夹中,如果没有问题,请按照以下说明操作niwlg2el4#
我在我的tsconfig.json文件中添加了
exclude
和include
,它工作了。pbpqsu0x5#
我也遇到了同样的问题,但测试只运行了一次。
原来我需要删除node_modules和yarn。锁定并重新安装所有内容

问题是我是使用快速入门主题
启动项目的
但是当我使用安装主题手动启动项目时,由于某种原因,它工作正常。

该文件
jest.config.ts
应该是
jest.config.js
