Example Code

python -m pip install typer-slim

Description

• I cannot install typer-slim in user's site-packages.
• typer (non-slim) works
• sudo works, but I want to stay in user-space

Operating System

Linux

Operating System Details

Amazon Linux 2023

The issue is specific to this OS and venv because I can install typer-slim on Ubuntu 24 (WSL2) and Windows native too.

To reproduce:

• start an EC2 instance with AMI "Deep Learning OSS Nvidia Driver AMI GPU PyTorch 2.8 (Amazon Linux 2023) 20260128"
• login with non-root (ec2-user)
• source /opt/pytorch/bin/activate
• python -m pip install -v typer-slim

Additional Context

No response

[svlandeg]

is typer itself already in the environment? Because that may explain it, they both rely on the same files and installing one may result in removal of the other. We're tracking this issue here.

Is there a specific reason why you want typer-slim instead of just typer?

[gabor-borbely]

Yes, it was already installed. I want slim because huggingface_hub requires it (they've decided to use typer in version 1.0.0 and onwards).

[svlandeg]

Ok, thanks for clarifying. So yes, it's the same underlying issue with typer and typer-slim, unfortunately. We're aware of this and it's high on our TODO list. To help us inform the best course of action, we've created a Typer survey which also asks about typer-slim. If you have time and would like to help us, feel free to fill it in!

Thanks 🤗 Should I comment/react to the "overlap" issue? I've seen that issue when I was searching for my error. But the OSError in pip install was strange and I didn't think that they were connected.

[svlandeg]

The OSError comes from the os.unlink command, because the typer files are being removed when installing typer-slim, and this raised the permission error. I'll link this discussion from the issue 🙏
