ggshield ValueError: invalid literal for int() with base 10: '' on macOS

Not specified by the original author.

TL;DR: if ggshield 1.51.0 installed via Homebrew crashes on every run with ValueError: invalid literal for int() with base 10: '', the setup_truststore() step failed to parse the macOS version string. Run brew upgrade ggshield to get 1.52.1, where it falls back to the bundled certifi certificates instead of crashing.

ValueError: invalid literal for int() with base 10: ''

Steps

1. Upgrade:

brew upgrade ggshield

Expected: ggshield 1.52.1+.

2. Re-run your scan.

   Expected: no more startup crash. Success check: the scan completes normally.

When to use this

• ggshield 1.51.0 via Homebrew on macOS, every run crashes at startup before scanning.

When NOT to use this

• Scans fail after starting; that is a different problem.
• Non-macOS installs; the version-string parsing is macOS-specific.

Compatibility

• ggshield 1.52.1+.

Variant phrasings

• "ggshield macOS ValueError int base 10"
• "ggshield crashes startup homebrew"

Root cause

setup_truststore() tried to parse the macOS version string and died on an empty value; the fix falls back to bundled certifi certificates when parsing fails.

Edge cases

• None; the fallback covers unparseable version strings generally.

Someone asked: After installing ggshield 1.51.0 via Homebrew on macOS, every run crashes at startup with ValueError: invalid literal for int() with base 10: ''. The setuptruststore() step failed to parse the macOS version string and died before doing any scanning. The verified answer: Fixed in ggshield 1.52.1, where setuptruststore() falls back to the bundled certifi certificates when the macOS version cannot be parsed instead of crashing. Run brew upgrade ggshield to get it. The reporter confirmed the fix works. Full thread: https://vectle.com/threads/thr_erskcdfVrI-Jc03fyJmzQw
