Since it's essential to use override to set the value of preferWheel as described in #948, how can you override both preferWheel and, for example, nativeBuildInputs? In this case

              dm-tree = super.dm-tree.override (
                old: {
                  preferWheel = false;
                  nativeBuildInputs = (old.nativeBuildInputs or [ ]) ++ [ pkgs.cmake ];
                }
              );

successfully disables the global setting of preferWheels = true for the target package but it seems nativeBuildInputs may not be successful ( or possibly cmake needs to be provided elsewhere or with additional configuration since the build fails where the target package setup.py calls cmake via subprocess to check that cmake is available on the PATH )

Thank you! ... that seems like what I tried, but maybe I didn't get it quite right or there's a more subtle issue with this particular package ... I'll try again

For example

              dm-tree = (super.dm-tree.override {preferWheel = false;}).overridePythonAttrs (
                old: {
                  nativeBuildInputs = (old.nativeBuildInputs or []) ++ [pkgs.cmake];
                }
              );

downloads the wheel and fails with "does not appear to contain CMakeLists.txt". That is successfully disabled, leading to the source download with dm-tree = super.dm-tree.override {preferWheel = false;}, but then the latter lacks cmake in the build env and fails for that reason.

Since it's essential to use override instead of overridePythonAttrs to set the value of preferWheel as described in #948, how can you override both preferWheel and, for example, nativeBuildInputs? In this case

              dm-tree = super.dm-tree.override (
                old: {
                  preferWheel = false;
                  nativeBuildInputs = (old.nativeBuildInputs or [ ]) ++ [ pkgs.cmake ];
                }
              );

successfully disables the global setting of preferWheels = true for the target package but it seems nativeBuildInputs may not be successful ( or possibly cmake needs to be provided elsewhere or with additional configuration since the build fails where the target package setup.py calls cmake via subprocess to check that cmake is available on the PATH ). The other option, which should both disable the wheel and include cmake in the nativeBuildInputs is below and in the thread.

Thank you! ... that seems like what I tried, but maybe I didn't get it quite right or there's a more subtle issue with this particular package ... I'll try again

For example

              dm-tree = (super.dm-tree.override {preferWheel = false;}).overridePythonAttrs (
                old: {
                  nativeBuildInputs = (old.nativeBuildInputs or []) ++ [pkgs.cmake];
                }
              );

persists in downloading the wheel and fails with "does not appear to contain CMakeLists.txt" because it has downloaded the wheel instead of the source. That is successfully disabled, leading to the source download with ONLY dm-tree = super.dm-tree.override {preferWheel = false;}, but then the latter lacks cmake in the build env and fails for that reason at the point linked above. I put a bit more context in the thread above.
