Help

The following cmd: flutter run

throws the following error

Launching lib/main.dart on Linux in debug mode...
Building Linux application...
CMake Error at CMakeLists.txt:3 (project):
  Running

   '/nix/store/qvbaf1639wmhn95ddmk23n5xldjaj76n-ninja-1.11.1/bin/ninja' '--version'

  failed with:

   no such file or directory


Error: Unable to generate build files

here’s the shell I’m using for work:

let
  pkgs = import <nixpkgs> {};
in pkgs.mkShell {
  packages = [
    pkgs.unzip
    pkgs.zip
    #pkgs.cargo
    #pkgs.rustc
    pkgs.rustup
    pkgs.vscodium
    pkgs.helix
    #pkgs.zed-editor
    pkgs.vim
    pkgs.universal-ctags
    #pkgs.gnome-builder
    pkgs.gitg
    #pkgs.chromedriver
    #pkgs.gedit
    pkgs.remmina
    pkgs.libiconv
    pkgs.mandoc
    pkgs.gcc
    pkgs.pkg-config
    pkgs.gnumake
    pkgs.openssl
    pkgs.python3
    pkgs.python311Packages.python-lsp-server
    pkgs.tmux
    pkgs.flutter
    pkgs.dbeaver-bin
    pkgs.ninja
  ];
  shellHook = ''
    export PS1="[nix-shell] \u at \h in \w\n» "
  '';
}

any tips how to fix?

From the logs, it looks like when you previously built the package, a build file was generated with hardcoded path, which must have changed with the changes in environment (or package version). You can verify by doing simple search rg ninja (uses ripgrep, can find grep equivalent), you will be able to find some CMakeFiles.

To resolve this, just delete the build folder and rebuild the project, it should work just fine.

Also remove gcc and gnumake from your shell, stdenv already provides those.
