We’re aware of this issue and a fix is on its way, but we can unblock you before it is rolled out. Can you add the following to your env block in dev.nix and rebuild your environment please?

Please let us know if that does not work.

env = {
    LD_LIBRARY_PATH = "${pkgs.lib.makeLibraryPath (with pkgs; [ stdenv.cc.cc ])}:$LD_LIBRARY_PATH";
};

If you’re getting errors from building environment, can you post the error you’re seeing please?

I’m running into the same or similar issue. Select the Gemini AI template with Flask to start a new Google IDX project and see an error when starting the preview. This is after adding the code snippet you included in my dev.nix file.

Thanks for trying IDX out Justin. This looks like a separate issue where somehow flask wasn’t installed. Can you install it manually with by running the commands in create-venv block inside dev.nix please? (and rebuild the environment after that)
