Is there a way to create the package.json based on the code?

I just start to study javascript and vue and trying to build the example project todo-vue. But it seems that the modules in package.json are too old and always fail during the “npm install”.

Is there a way that the package.json file can be updated with the latest version or regenerated from the project code? Or is there a way to make the project work?

Not sure it is a valid question. But I did try some example projects and all failed due to the mdoule version.
