The linked review comment flagged a type mismatch: install_pyenv() was annotated to return str but never returned a value.
This update applies that comment directly and limits scope to the requested change.

• Type annotation correction

  • Updated install_pyenv signature in src/tests4py/environment.py:
    • from -> str
    • to -> None
  • No runtime logic, control flow, or call sites were changed.

• Why this matters

  • Removes a misleading contract for callers and static analysis.
  • Keeps the function API consistent with its side-effect-only implementation.

# before
def install_pyenv() -> str:

# after
def install_pyenv() -> None:

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• pyenv.run
  • Triggering command: /usr/bin/curl curl REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
