pip install rpm-vercmp

Common errors

error ModuleNotFoundError: No module named 'rpm_vercmp' ↓

cause Incorrect import path; the module uses underscore, not hyphen.

fix

Use from rpm_vercmp import rpmvercmp (note underscore).

error AttributeError: module 'rpm_vercmp' has no attribute 'rpmvercmp' ↓

cause Trying to import the module directly and then call it incorrectly.

fix

Correct import: from rpm_vercmp import rpmvercmp then use rpmvercmp(ver1, ver2).

gotcha The function returns integers (1, -1, 0) for comparison results, not True/False or a boolean. Be careful in conditional checks. ↓

fix Use `rpmvercmp(a, b) > 0` instead of `rpmvercmp(a, b)` in boolean contexts.

gotcha Version strings must be valid RPM version strings. Non-standard characters or malformed input may cause unexpected results or errors. ↓

fix Ensure input strings follow RPM version format (e.g., '1.2.3', '1.2.3-1').

Compare two RPM version strings.

from rpm_vercmp import rpmvercmp

result = rpmvercmp('1.2.3', '1.2.4')
print(result)  # 1 if first > second, -1 if first < second, 0 if equal
