CRLF line endings causing /usr/bin/env: ‘bash\r’: No such file or directory on WSL

[stoneHee99]

Problem

When using pyenv-virtualenv on WSL (Windows Subsystem for Linux), some shell scripts can produce the following error:

/usr/bin/env: ‘bash\r’: No such file or directory

This happens when the repository is cloned with CRLF (Windows-style) line endings, which are incompatible with bash scripts on Linux.

Environment

• WSL2 (Ubuntu 22.04)
• Git default config with core.autocrlf=true
• pyenv + pyenv-virtualenv
• Zsh or Bash

Reproduction

1. Clone the repository from Windows Git client (CRLF enabled)
2. Add eval "$(pyenv virtualenv-init -)" to .zshrc or .bashrc
3. Run source ~/.zshrc
4. Error: /usr/bin/env: ‘bash\r’: No such file or directory

Proposed Solution

Add a .gitattributes file to enforce LF line endings for shell scripts:

*.sh text eol=lf

This will ensure shell scripts are always checked out with Unix-compatible line endings, even on Windows environments.

Additional Notes

• This issue does not affect native Linux or macOS users
• This change would improve developer experience for WSL users significantly
