fix: suppress oclif TypeScript warning with NODE_ENV=production

[johnlindquist]

Summary

• Fix the "Could not find typescript" warning by setting NODE_ENV=production
• Simple one-line fix that properly prevents oclif from attempting TypeScript detection

Problem

The previous fix didn't work because the warning is triggered during the import of @oclif/core, before the execute() function is called.

Solution

Set process.env.NODE_ENV = 'production' before importing @oclif/core. This prevents oclif from checking for TypeScript in production environments.

Test Plan

• Tested locally with node bin/run.js help - no warning
• Tested with tsconfig.json in current directory - no warning
• All existing tests pass
• Verified the fix with actual usage scenario

🤖 Generated with Claude Code

Summary by CodeRabbit

• Chores
  • Improved handling of environment settings to ensure production mode is activated earlier during script execution.

Walkthrough

The script in bin/run.js was updated to set the NODE_ENV environment variable to 'production' at the very start, before any module imports. The previous directory path resolution logic was removed, and the execution function now uses import.meta.url for its directory option. No changes were made to exported or public entities.

Changes

File(s)	Change Summary
bin/run.js	Sets NODE_ENV to 'production' before imports, removes directory path logic, uses import.meta.url for execution, and removes the development: false flag.

Poem

🐇
Early in the script, a change takes root,
Setting production mode—no time to reboot!
Gone are the paths, the flags of old,
Now import.meta.url is bold.
With a hop and a skip, the run script’s new,
The rabbit approves—so should you!

bin/run.js (2)

3-4: LGTM! Correct placement and clear documentation.

Setting NODE_ENV to 'production' before importing @oclif/core is the right approach to suppress the TypeScript detection warning. The placement before imports ensures it takes effect early, and the comment provides clear context.

14-14: No change needed for import.meta.url usage

The execute function in ESM contexts accepts a file URL for the dir option, and you can see the same pattern in bin/dev.js:

• bin/dev.js uses:

  await execute({development: true, dir: import.meta.url})

• bin/run.js mirrors this by passing import.meta.url directly.

Oclif’s internal implementation handles converting the file URL to a directory path, so switching to __dirname is unnecessary.

Likely an incorrect or invalid review comment.
