    }
  }

  import ncu from "npm-check-updates";
  
  console.log(await ncu.run());

Hi, thanks for reporting.

semver-utils is included in the package.json, but maybe Rollup is not bundling it properly. Do you know how to force Rollup to include a library?

[regseb]

semver-utils is in the "devDependencies" that aren't published. It should be put in "dependencies".

[raineorshine]

Vite uses Rollup to automatically tree shake the devDependencies and bundle them for production.

I'm sure it's just a matter of adding it to the Vite config. I'll play around with it next chance I get :).
