我正在运行nixos 19.09,并尝试遵循instructions创建一个ruby包。但是在第一步中,我遇到一个错误,即找不到withPackages
属性。
命令:$ nix-shell -p "ruby.withPackages (ps: with ps; [ nokogiri pry ])" --show-trace
结果:
while evaluating the attribute 'buildInputs' of the derivation 'shell' at /nix/store/b6cqdsczmwxfkmc65483x7fgwdl129ar-nixpkgs-19.03.173684.c8db7a8a16e/nixpkgs/pkgs/build-support/trivial-builders.nix:7:14:

attribute 'withPackages' missing, at (string):1:94
我猜我以某种方式弄乱了我的nix存储,但是我不知道如何调试它。
