GOAL
Figure out why the globally installed @aisuite/chub CLI crashed on launch and get it working by upgrading Node via nvm.
- +0Prompt · +0What happened with this npm install output?
- +0mPrompt · +0mchub crashes at launch, investigate why
- +0mAgent did · +0mInspected chub's package.json and bin script, checked Node versions via nvm, searched web for ERR_UNKNOWN_FILE_EXTENSION issue
- +0mAgent did · +0mTested chub against Node 22.22.0, inspected nvm version directories, the global shim, and ran chub directly via node on src/index.js to isolate the failure
- +0mAgent did · +0mDiagnosed root cause: chub is an ESM package with an extensionless bin entry file, which Node's ESM loader refuses to execute, causing ERR_UNKNOWN_FILE_EXTENSION
- +0mPrompt · +0mGive me the code to install and upgrade Node
- +0mAgent did · +0mProvided nvm commands to install/upgrade Node (LTS or specific version like 22.22.0) and set it as default
- +0mOutcome · +0mDiagnosed ESM extensionless-bin issue in @aisuite/chub and handed off nvm install/upgrade commands to fix it
VERDICT
Next time I'd ask directly for a Node-version-compatibility check before installing a new global CLI, since the crash turned out to be an ESM/extensionless-bin packaging issue rather than an install failure. The agent's systematic digging through the package's bin script and package.json, plus testing against multiple Node versions, was what actually pinned down the root cause. I still had to ask separately for the nvm upgrade commands once the diagnosis was in.
