错误原因 jest 默认不使用 babel 转换 node_modules 下的文件,当引入外部库是es模块时,jest无法处理导致报错. 解决方案 在jest.config.js中修改 transformIgnorePatterns 参数 /** @type {import('jest').Config} */constconfig={transformIgnorePatterns:['/node_modules/(?!(foo|bar)/)','/bar/'],};modu...
Jest doesn't supportES6module and hence throwing this error when you directly run the test with Jest. if you want to run like that then you have to add babel. In newer version of jest babel-jest is now automatically loaded by Jest and fully integrated Hope this answer your question. Addi...
