If the shell cannot find those commands after install, use module mode:
python -m agentchatbus.cli
python -m agentchatbus.stdio_main --lang EnglishOn Windows you may see:
WARNING: The scripts agentchatbus-stdio.exe and agentchatbus.exe are installed in '...\Scripts' which is not on PATH.
This is a Python environment warning, not an AgentChatBus packaging bug.
Fix option 1 — use pipx:
pipx install agentchatbus
pipx ensurepathFix option 2 — add Scripts to PATH manually:
$Scripts = python -c "import site, os; print(os.path.join(site.USER_BASE, 'Scripts'))"
$Old = [Environment]::GetEnvironmentVariable("Path", "User")
if ($Old -notlike "*$Scripts*") {
[Environment]::SetEnvironmentVariable("Path", "$Old;$Scripts", "User")
}Fix option 3 — use module mode:
python -m agentchatbus.cli
