Vue2 and unit tests : SyntaxError: Cannot use import statement outside a module-CodePudding

I am doing unit tests with vue-utils on the front-end of an application written in vue2.

When I run my test, I get this error: SyntaxError: Cannot use import statement outside a module (I don't even need the problematic module in my test.)

I have looked at several answers on the subject (including adding "type": "module" in package.json or add extension ".mjs") but I always get an additional error after testing the solution. I work with node/14.19.2.

Do you have any idea? I don't know which file to show you, don't hesitate to ask me for my code

CodePudding user response：

I had a same issue and in my case the Visual Studio added (modules/js file). Check the top of your vue/javascript code, is there any imported file or not!

I solve my issue by adding this line:

transformIgnorePatterns: [
    'node_modules/(?!module_name)'   ]

in my jest.config.js file
