Hi Matt, > Could it be because only wheel files are hosted and not any source? I often have to change the source of Python packages to use the source repository instead of fetching from pypi because the latter doesn't include test suites. However, the build still fails in the sanity-check phase even using the source repository as source and disabling tests (because the app doesn't have tests yet). Here is the modified package: ~~~ (use-modules (guix packages) (guix download) (guix git-download) (gnu packages python) (gnu packages qt) (guix build-system python) ((guix licenses) #:prefix license:)) (define-public python-t-rex-typer (package (name "python-t-rex-typer") (version "0.1.5") (source (origin (method git-fetch) (uri (git-reference (url "https://github.com/excalamus/t_rex_typer") (commit "e9e23cf"))) (file-name (git-file-name name version)) (sha256 (base32 "1vw6c7p7yzl5rza2cmgiwyfxkr868i7mv3wnqvmyapy4p97axyc1")))) #; (source (origin (method url-fetch) (uri (pypi-uri "t_rex_typer" version)) (sha256 (base32 "0y08zacchwkx95dla1lbrqkxfnsknhm8ymr6ad08vijbwf5xircp")))) (build-system python-build-system) (arguments '(#:tests? #f)) ; There are no tests to run.
