Fix for libstdc++.so.6 Missing Library Issue

Problem

The server fails to start with error: ImportError: libstdc++.so.6: cannot open shared object file: No such file or directory

Solution

You need to manually create/modify these files since the system prevents automated editing:

1. Create `replit.nix` file in project root

Create a new file called replit.nix in the project root with this exact content:

{ pkgs }:
pkgs.mkShell {
  buildInputs = [
    pkgs.python311Full
    pkgs.cacert
    pkgs.gcc
    pkgs.libgcc
    pkgs.stdenv.cc.cc.lib
    pkgs.postgresql
  ];
}

2. Modify `.replit` file

Find the .replit file and comment out the [nix] section by adding # at the start of each line:

# [nix]
# channel = "stable_24_05"
# packages = ["cacert", "gcc"]

3. Restart Environment

After making these changes:

Save both files
Restart your Replit environment completely
The pkgs.stdenv.cc.cc.lib package should provide the missing libstdc++.so.6 library

4. Test Server

Once the environment restarts, test if the server starts successfully:

python main.py

Why This Works

The pkgs.stdenv.cc.cc.lib package provides the C++ standard library that contains libstdc++.so.6, which is required by the grpcio package used by google-generativeai.
