Here’s the code of replit.nix

{ pkgs }: {
  deps = [
  env = {
    PYTHON_LD_LIBRARY_PATH = pkgs.lib.makeLibraryPath [
    PYTHONHOME = "${pkgs.python311}";
    PYTHONBIN = "${pkgs.python311}/bin/python3.11";
    LANG = "en_US.UTF-8";
    STDERREDBIN = "${pkgs.replitPackages.stderred}/bin/stderred";
    PRYBAR_PYTHON_BIN = "${pkgs.replitPackages.prybar-python311}/bin/prybar-python311";

Hey @truongkhoawastaken!

What did you add/change in replit.nix?

It looks like you are trying to use python 3.11
Here’s a few more steps for it to work:

In replit.nix file

From deps, remove:

  • pkgs.replitPackages.prybar-python311
  • pkgs.replitPackages.stderred

From env, remove:


In .replit file

Delete the entire [interpreter] block, possibly lines 15-27
Change channel, possibly on line 13, from "stable-22_11" to "stable-23_05"
In PYTHONPATH, possibly on line 18, update the 2 occurrences of 3.10 to 3.11

In venv folder

In venv/lib folder, rename folder python3.10 to python3.11. This may take a while
In venv/include, if there is one, rename folder python3.10 to python3.11


Refresh, or reload the shell, and now your repl runs python 3.11, with a working packages tab

Thank you for your help! But when I install a package , it show this error in pip

~/test$ pip install discord
error: externally-managed-environment

    To use Python with Nix and nixpkgs, have a look at the online documentation:

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

[notice] A new release of pip is available: 23.0.1 -> 23.2.1
[notice] To update, run: python3.11 -m pip install --upgrade pip

Try using poetry add instead of pip install
Or use the convenient packages tab in the IDE
