<pre> | |||
anonymous function at /path/to/your-package.nix called without required argument 'some-dependency' | |||
</pre> | |||
Usually, a dependency (some-dependency) is not available on a certain platform, | |||
for example on <code>aarch64-darwin</code> | |||
Solution: Make it an optional dependency: | |||
<pre> | |||
{ lib | |||
, stdenv | |||
, some-dependency ? null | |||
, another-dependency | |||
}: | |||
stdenv.mkDerivation { | |||
buildInputs = | |||
[ another-dependency ] | |||
++ lib.optionals (!stdenv.isDarwin) [ some-dependency ] | |||
# some-dependency is missing on darwin | |||
; | |||
} | |||
