错误信息

CreateApp › trigger lifecycle
│     Jest encountered an unexpected token
│     Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support 
│     Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.
│     By default "node_modules" folder is ignored by transformers.
│     Here's what you can do:
│      • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it.
│      • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript
│      • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
│      • If you need a custom transformation specify a "transform" option in your config.
│      • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.
│     You'll find more details and examples of these config options in the docs:
│     https://jestjs.io/docs/configuration
│     For information about custom transformations, see:
│     https://jestjs.io/docs/code-transformation
