PowerShell with $ErrorActionPreference = 'Stop' treats ANY stderr
output from native commands as a terminating NativeCommandError —
even successful git operations that write progress to stderr
(e.g. 'Cloning into ...').
Fix: temporarily set $ErrorActionPreference = 'Continue' around all
git commands (clone, fetch, checkout, pull, submodule update). This
lets git run normally while preserving strict error handling for
the rest of the installer.
The Windows installer was swallowing uv python install errors with
| Out-Null, making failures impossible to diagnose. Now:
- Shows the actual uv error output when installation fails
- Falls back to finding any existing Python 3.10-3.13 on the system
- Falls back to system python if available
- Shows helpful manual install instructions (python.org URL + winget)
- Add scripts/install.cmd batch wrapper for CMD users (delegates to install.ps1)
- Add _find_shell() in local.py: detects Git Bash on Windows via
HERMES_GIT_BASH_PATH env var, shutil.which, or common install paths
(same pattern as Claude Code's CLAUDE_CODE_GIT_BASH_PATH)
- Use _find_shell() in process_registry.py for background processes
- Fix hermes_cli/gateway.py: use wmic instead of ps aux on Windows,
skip SIGKILL (doesn't exist on Windows), fix venv path
(Scripts/python.exe vs bin/python)
- Update README with three install commands (Linux/macOS, PowerShell, CMD)
and Windows native documentation
Requires Git for Windows, which bundles bash.exe. The terminal tool
transparently uses Git Bash for shell commands regardless of whether
the user launched hermes from PowerShell or CMD.
Updated the README and messaging documentation to clarify the two modes for WhatsApp integration: 'bot' mode (recommended) and 'self-chat' mode. Improved setup instructions to guide users through the configuration process, including allowlist management and dependency installation. Adjusted CLI commands to reflect these changes and ensure a smoother user experience. Additionally, modified the WhatsApp bridge to support the new mode functionality.
Updated the install.sh script to set DEBIAN_FRONTEND and NEEDRESTART_MODE environment variables for non-interactive package installations on Ubuntu and Debian. This change ensures that prompts from needrestart and whiptail do not block the installation process, improving automation for system package installations.
- Updated the installation script to check for necessary build tools on Debian/Ubuntu systems and prompt the user to install them if missing.
- Improved user interaction by redirecting input from /dev/tty for prompts, ensuring compatibility when the script is piped from curl.
- Added checks to verify the successful installation of the main package and provide guidance if installation fails.
- Enhanced the handling of shell configuration files to ensure ~/.local/bin is added to PATH for various shell types.
Root cause: the install script uses `set -e` (exit on error) and `read -p`
for interactive prompts. When running via `curl | bash`, stdin is a pipe
(not a terminal), so `read -p` hits EOF and returns exit code 1. Under
`set -e`, this silently aborts the entire script before hermes is installed.
Fix: detect non-interactive mode using `[ -t 0 ]` (standard POSIX test for
terminal stdin) and skip all interactive prompts when running in piped mode.
Clear messages are shown instead, telling the user what to run manually.
Changes:
- Add IS_INTERACTIVE flag at script start ([ -t 0 ] check)
- Guard sudo package install prompt (the direct cause of #69)
- Guard setup wizard (calls interactive hermes setup)
- Guard WhatsApp pairing and gateway install prompts
All other prompts use the same read -p pattern and would fail the same way
in piped mode, so they are all guarded for completeness.
