How is a package in umd or commonjs build packaged using vue-cli referenced in a vite project?

[xiaoxuehai]

I have a vue2 project that is based on vue-cli and another vue2 project that is based on vite. Now I want to package the vue-cli project as a component to be used by the vite project, but I am running into problems.

I import vue-cli packaged components into vite, but The message "SyntaxError: the requested module '/src/lib/custom/custom-form.umd.js? t=1734861457787' does not provide an export named 'default'”

Is there a good way to do this
