Describe the Bug

When attempting to package a Node.js application that uses the axios library (version 1.6.3), the pkg command fails to create functional single executable and issues warnings about not being able to generate bytecode for axios files.

Steps to Reproduce:

1. Include axios version 1.6.3 in your project's dependencies.
2. Utilize axios in your application.
3. Run the packaging command: pkg . -t node18-macos-x64.

Similar tickets: vercel/pkg#2042 and vercel/pkg#1873

Expected Behavior

The application should be successfully packaged into binaries as specified in the main and exports fields the package.json

To Reproduce

The single executables are created, and the following warnings are displayed:

> Warning Failed to make bytecode node18-x64 for file /snapshot/bright-cli/node_modules/axios/lib/platform/node/classes/URLSearchParams.js
> Warning Failed to make bytecode node18-x64 for file /snapshot/bright-cli/node_modules/axios/lib/helpers/throttle.js

However, while running the single executable, it prints the following error message:

Error: Cannot find module '/snapshot/bright-cli/node_modules/axios/dist/node/axios.cjs'
1) If you want to compile the package/file into executable, please pay attention to compilation warnings and specify a literal in 'require' call. 2) If you don't want to compile the package/file into executable and want to 'require' it from filesystem (likely plugin), specify an absolute path in 'require' call using process.cwd() or process.execPath.

This is a known bug, see #16

@robertsLando I see. However, Axios, like many other dependencies, uses the exports field to declare multiple artifacts for both CommonJS and ESM. Adding support for ESM does not resolve the issue with loading CommonJS entries declared in the exports field.
