Could not parse Gemfile
Error message
Could not parse Gemfile
What it means
While detecting Ruby frameworks, detectProject warns that it could not read the Gemfile (the catch around readFile/Gemfile processing fired). Rails/Sinatra detection is skipped and detection continues with structure checks.

Solutions
- Verify readability: cat Gemfile
- Fix permissions (chmod 644 Gemfile)
- If the file is corrupted, restore from version control
Defensive patterns
Strategy: validation
Validate before calling
import { access, constants } from 'fs/promises';
await access('Gemfile', constants.R_OK).catch(() => { /* skip ruby detection */ }); Prevention
- Keep Gemfile readable (644)
- Restore corrupted Gemfiles from version control
When it happens
Trigger: Gemfile exists but is unreadable (EACCES), is a directory, or an unexpected throw occurs while inspecting its contents.
Common situations: Permission-restricted Gemfile, Gemfile locked by another process, or an exotic Gemfile encoding that makes readFile throw.
