ImportError: libstdc++.so.6: cannot open shared object file: No such file or directory

I’m trying to import a package called spacy for NLP, but I keep getting this error:

Traceback (most recent call last):

ImportError: libstdc++.so.6: cannot open shared object file: No such file or directory

I did some research on this and this is what I’ve tried:

• Adding this to the .nix file:

  shellHook = ''
    # fixes libstdc++ issues and libgl.so issues
    LD_LIBRARY_PATH=${pkgs.stdenv.cc.cc.lib}/lib/:/run/opengl-driver/lib/
  ''

• Putting the LD_LIBRARY_PATH part outside of the string

• Replacing :/run/opengl-driver/lib/ with libstdc++.so.6

Please help me as I really do not know what to do from here…

I was able to get spacy to work by installing it from the package manager first.

Then you might need something like en_core_web_sm and you install this by running python -m spacy download en_core_web_sm in the shell.

The Problem

I found out the issue, it was because I commented out the [interpreter] part of the .replit file.

This part add a very important part that was setting the LD_LIBRARY_PATH environment variable to python’s pre-defined library path.

That was causing the error in the first place (as packages did not know where they were located… correct me if I’m wrong)

The Solution

Obviously, you can just un-comment the interpreter part , BUT you can also just extract eny definition in the “env” part of the [interpreter.command] section into the [env] section instead. Like this:

#	env = { LD_LIBRARY_PATH = "$PYTHON_LD_LIBRARY_PATH" }
#									|
[env]#							    V
LD_LIBRARY_PATH = "$PYTHON_LD_LIBRARY_PATH" 

What your `.replit` file should look like

# The command that runs the program. If the interpreter field is set, it will have priority and this run command will do nothing
run = "python3 main.py"

# The primary language of the repl. There can be others, though!
language = "python3"
entrypoint = "main.py"
# A list of globs that specify which files and directories should
# be hidden in the workspace.
hidden = ["venv", ".config", "**/__pycache__", "**/.mypy_cache", "**/*.pyc"]

# Specifies which nix channel to use when building the environment.
