Hi Bianca,

The ".taskslab11419" section of your version name doesn't meet the requirements for version numbers described in https://www.python.org/dev/peps/pep-0440/#public-version-identifiers, as the only non-numeric text elements permitted are "a" (alpha releases), "b" (beta releases), "c" (release candidates), "dev" (dev releases), and "post" (post-releases).

The simplest resolution would be to drop the ".taskslab11419" section, and just make the version 0.2.0 instead. Alternatively, if keeping the number is important, you could make a dev release (0.2.0.dev11419), or use a 4 segment version number (0.2.0.11419).

Cheers, Nick.

Hi Nick and Donald,

I’m emailing you because I can’t seem to resolve an issue with my project wherein I try to install using pip command and it returns:

WARNING: Built wheel for SomeProject is invalid: Metadata 1.2 mandates PEP 440 version, but '0.2.0.taskslab11419' is not

Failed to build SomeProject

I’ve read your documentation with PEP 440 version but my version name *0.2.0.taskslab11419* does not seem to be invalid based on your documentation. Can you guys help me out here? I’ve been trying to fix this for almost a week now but to no avail.

Btw, I’m using python3.8 and pip 21.1 version.

Hoping to hear from you soon.

Thank you and cheers,

Bianca
