```⚠ ./node_modules/.pnpm/better-auth@1.0.18/node_modules/better-auth/dist Package oslo can't be external The request oslo matches serverExternalPackages (or the default list). The request could not be resolved by Node.js from the project directory. Packages that should be external need to be installed in the project directory, so they can be resolved from the output files. Try to install it into the project directory by running npm install oslo from the project directory.``` how to fix that?
