Question

我来自这里https://github.com/NixOS/nixpkgs/issues/28816，我正在寻找一种方法来将不纯的env变量传递给nix-build

在本地构建应该会有所帮助，但我无法使该示例正常工作，有人可以帮助我吗--option builders ''，并将当前用户添加到trusted-users并没有帮助

code=`<<'EOF'
with import <nixpkgs> {};
stdenv.mkDerivation {
  name="impure";
  phases=["buildPhase"];
  impureEnvVars=["IMPURE"];
  buildPhase=''
    env | grep IMPURE
    if [ -z $IMPURE ]; then
      echo "Error"
      exit 1
    fi
    echo "foo" > $out
  '';
}
EOF`
export IMPURE=iop; nix-build --option builders "" --option trusted-users $USER -E "$code"

结果

$ code=`<<'EOF'
with import <nixpkgs> {};
stdenv.mkDerivation {
  name="impure";
  phases=["buildPhase"];
  impureEnvVars=["IMPURE"];
  buildPhase=''
    env | grep IMPURE
    if [ -z $IMPURE ]; then
      echo "Error"
      exit 1
    fi
    echo "foo" > $out
  '';
}
EOF`
export IMPURE=iop; nix-build --option builders "" --option trusted-users $USER -E "$code"

these derivations will be built:
  /nix/store/dvsl63bq4qmlrs79wbxvc3vrbxzw6xad-impure.drv
building '/nix/store/dvsl63bq4qmlrs79wbxvc3vrbxzw6xad-impure.drv'...
building
impureEnvVars=IMPURE
buildPhase=env | grep IMPURE
if [ -z $IMPURE ]; then
Error
builder for '/nix/store/dvsl63bq4qmlrs79wbxvc3vrbxzw6xad-impure.drv' failed with exit code 1
error: build of '/nix/store/dvsl63bq4qmlrs79wbxvc3vrbxzw6xad-impure.drv' failed

如何将impureEnvVars传递给本地nix-build而不是nix-daemon /如何使用nix-build禁用远程构建？
