I’m stuck on improving my solution. I’ve tried to run it locally following the README.md file and some other answers in this forum, but i cannot run without problem. Here are my logs: ```auto ➜ ./your_program.sh bash: ./your_program.sh: cannot execute: required file not found ``` Here’s a link to my repo: [gabrielbudke/codecrafters-claude-code-python: Build your own Claude Code](https://github.com/gabrielbudke/codecrafters-claude-code-python) ---

Hey @gabrielbudke, could you share which OS you’re using and a screenshot of how you’re running it? Also, could you share the output of running `pwd` and `ls` as well? ---

Hello, @andy1li! I’m using WSL with Ubuntu. ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/3X/f/c/fc4a6d367e53ae4e78faad284f4fcd55305bcebb.png) ---

Thanks for sharing the screenshot! Hmm, that does look unusual. Could you try running `file your_program.sh` and `bash your_program.sh` and share the output as well? ---

Could you check whether this is coming from your editor or your Git settings? @gabrielbudke One quick way to fix it: ```auto sudo apt install dos2unix dos2unix your_program.sh ``` Let me know how it goes! ---
