Removes Homebrew and PyPI wheel/sdist as Hermes distribution paths while
preserving the supported source, Docker, and Nix workflows.
Changes:
- Removes the Homebrew formula, PyPI publish workflow, sdist manifest
(MANIFEST.in), and wheel/sdist release-attachment logic from scripts/release.py.
- Keeps setuptools metadata and entry points required by editable installs
and Docker/Nix builds, but adds a setup.py guard that rejects wheel/sdist
builds outside a sealed Nix derivation (HERMES_NIX_BUILD=1).
- Removes pip/Homebrew install detection, PyPI update checks, the pip
self-update path, the deprecation-banner state, the postinstall subcommand,
wheel data-directory fallbacks in agent/i18n.py and hermes_constants.py,
and the ACP Registry manifest/version-lockstep release logic.
- Adds /nix/store/ path detection so `nix run` / `nix profile install`
installs (which don't set HERMES_MANAGED) are correctly identified as
"nix" rather than falling through to "git"/"unknown".
- Retired install-method values ("pip", "homebrew") in existing
.install_method stamps (both code-scoped and home-scoped) are ignored by
the allowlist reader and fall through to "unknown" instead of resurrecting
a retired enum value.
- Updates Nix packaging to ship bare runtime data (locales, optional-mcps)
through store symlinks and wrapper env vars instead of wheel data-files.
- Removes the ACP Registry manifest/icon and their version-lockstep tests.
- Deletes or rewrites packaging, pip-update, Homebrew, and ACP Registry
tests; adds parametrized coverage for the packaging build guard covering
BOTH sdist and wheel paths (the guards live in separate cmdclass entries
— a passing sdist test proves nothing about the wheel path).
- Updates installation/platform documentation and related user-facing copy.
- Adjusts the supply-chain scan so deleted install-hook files do not trigger
a finding, while additions or modifications still require the existing
ci-reviewed label gate.
Supported installation paths (unchanged):
- git installer (install.sh)
- Docker
- Nix/NixOS
- editable development installs (uv sync, uv pip install -e ., pip install -e .)

## Quick Install
|
|
### With the Hermes Desktop installer on macOS or Windows (recommended)
|
|
To easily install the command-line and desktop applications, [download the Hermes Desktop installer](https://hermes-agent.nousresearch.com/) from our website and run it.
|
|
|
|
### Without Hermes Desktop:
|
|
For a command-line only install without Hermes Desktop, run:
|
|
|
|
#### Linux / macOS / WSL2 / Android (Termux)
|
|
```bash
|
|
curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
|
|
```
|
|
|
|
#### Windows (native)
|
|
|
|
Run in powershell:
|
|
```powershell
|
|
iex (irm https://hermes-agent.nousresearch.com/install.ps1)
|
|
```
|
|
|
|
If you want to install & run Hermes Desktop after a command-line only install, simply run
|
|
```bash
|
|
hermes desktop
|
|
```
|
|
|
|
### What the Installer Does
|
|
|
|
The installer handles everything automatically — all dependencies (Python, Node.js, ripgrep, ffmpeg), the repo clone, virtual environment, global `hermes` command setup, and LLM provider configuration. By the end, you're ready to chat.
|
|
|
|
#### Install Layout
|
|
|
|
Where the installer puts things depends on whether you're installing as a normal user or as root:
|
|
|
|
| Installer | Code lives at | `hermes` binary | Data directory |
|
|
| -------------------------------------- | ------------------------------ | --------------------------------------- | ------------------------------------ |
|
|
| Per-user (git installer) | `~/.hermes/hermes-agent/` | `~/.local/bin/hermes` (symlink) | `~/.hermes/` |
|
|
| Root-mode (`sudo curl … \| sudo bash`) | `/usr/local/lib/hermes-agent/` | `/usr/local/bin/hermes` | `/root/.hermes/` (or `$HERMES_HOME`) |
|
|
|
|
The root-mode **FHS layout** (`/usr/local/lib/…`, `/usr/local/bin/hermes`) matches where other system-wide developer tools land on Linux. It's useful for shared-machine deployments where one system install should serve every user. Per-user config (auth, skills, sessions) still lives under each user's `~/.hermes/` or explicit `HERMES_HOME`.
|
|
|
|
### After Installation
|
|
|
|
Reload your shell and start chatting:
|
|
|
|
```bash
|
|
source ~/.bashrc # or: source ~/.zshrc
|
|
hermes # Start chatting!
|
|
```
|
|
|
|
To reconfigure individual settings later, use the dedicated commands:
|
|
|
|
```bash
|
|
hermes model # Choose your LLM provider and model
|
|
hermes tools # Configure which tools are enabled
|
|
hermes gateway setup # Set up messaging platforms
|
|
hermes config set # Set individual config values
|
|
hermes config get # Inspect individual config values
|
|
hermes setup # Or run the full setup wizard to configure everything at once
|
|
```
|
|
|
|
:::tip Fastest path: Nous Portal
|
|
One subscription covers 300+ models plus the [Tool Gateway](/user-guide/features/tool-gateway) (web search, image generation, TTS, cloud browser). Skip the per-tool key juggling:
|
|
|
|
```bash
|
|
hermes setup --portal
|
|
```
|
|
|
|
That logs you in, sets Nous as your provider, and turns on the Tool Gateway in one command.

## Prerequisites
|
|
|
|
**Installer:** On non-Windows platforms, the only prerequisite is **Git**. On Linux, also make sure `curl` and `xz-utils` are available (the installer downloads Node.js as a `.tar.xz` archive). The desktop app additionally requires `g++` (or `build-essential` on Debian/Ubuntu) to compile native modules. The installer automatically handles everything else:
|
|
|
|
- **uv** (fast Python package manager)
|
|
- **Python 3.11** (via uv, no sudo needed)
|
|
- **Node.js v22** (for browser automation and WhatsApp bridge)
|
|
- **ripgrep** (fast file search)
|
|
- **ffmpeg** (audio format conversion for TTS)
|
|
|
|
:::info
|
|
You do **not** need to install Python, Node.js, ripgrep, or ffmpeg manually. The installer detects what's missing and installs it for you. Just make sure `git` is available (`git --version`). On Linux, ensure `curl` and `xz-utils` are installed (`sudo apt install curl xz-utils` on Debian/Ubuntu). For the desktop app, also install `build-essential` (`sudo apt install build-essential`).

|
|
|
|
:::tip Nix users
|
|
Nix is **no longer an explicitly supported install path** (best-effort only). If you already use Nix (on NixOS, macOS, or Linux), there's a dedicated setup path with a Nix flake, declarative NixOS module, and optional container mode. See the **[Nix & NixOS Setup](./nix-setup.md)** guide.

## Manual / Developer Installation
|
|
|
|
If you want to clone the repo and install from source — for contributing, running from a specific branch, or having full control over the virtual environment — see the [Development Setup](../developer-guide/contributing.md#development-setup) section in the Contributing guide.

## Non-Sudo / System Service User Installs
|
|
|
|
Running Hermes as a dedicated unprivileged user (e.g. a `hermes` systemd service account, or any user without `sudo` access) is supported. The only thing on the install path that genuinely needs root is Playwright's `--with-deps` step, which `apt`-installs shared libraries (`libnss3`, `libxkbcommon`, etc.) used by Chromium. The installer detects whether sudo is available and gracefully degrades when it isn't — it will install the Chromium binary into the service user's own Playwright cache and print the exact command an administrator needs to run separately.
|
|
|
|
**Recommended split (Debian/Ubuntu):**
|
|
|
|
1. **One time, as an admin user with sudo**, install the system libraries Chromium needs:
|
|
```bash
|
|
sudo npx playwright install-deps chromium
|
|
```
|
|
(You can run this from anywhere — `npx` will fetch Playwright on the fly.)
|
|
|
|
2. **As the unprivileged service user**, run the regular installer. It will detect the missing sudo, skip `--with-deps`, and install Chromium into the user's local Playwright cache:
|
|
```bash
|
|
curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
|
|
```
|
|
|
|
If you want to skip the Playwright step entirely — for example because you're running headless and don't need browser automation — pass `--skip-browser`:
|
|
```bash
|
|
curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash -s -- --skip-browser
|
|
```
|
|
|
|
3. **Make `hermes` available to the service user's shells.** The installer writes the launcher to `~/.local/bin/hermes`. System service accounts often have a minimal PATH that doesn't include `~/.local/bin`. Either add it to the user's environment, or symlink the launcher into a system location:
|
|
```bash
|
|
# Option A — add to the service user's profile
|
|
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
|
|
|
|
# Option B — symlink system-wide (run as an admin)
|
|
sudo ln -s /home/hermes/.hermes/hermes-agent/venv/bin/hermes /usr/local/bin/hermes
|
|
```
|
|
|
|
4. **Verify:** `hermes doctor` should now run cleanly. If you get `ModuleNotFoundError: No module named 'dotenv'`, you're invoking the repo source `hermes` file (`~/.hermes/hermes-agent/hermes`) with system Python instead of the venv launcher (`~/.hermes/hermes-agent/venv/bin/hermes`) — fix step 3.
|
|
|
|
The same pattern works on Arch (the installer uses pacman with the same sudo-detection logic), Fedora/RHEL, and openSUSE — those distros don't support `--with-deps` at all, so an administrator always installs the system libraries separately. The relevant `dnf`/`zypper` commands are printed by the installer.
|

## Troubleshooting
|
|
|
|
| Problem | Solution |
|
|
|---------|----------|
|
|
| `hermes: command not found` | Reload your shell (`source ~/.bashrc`) or check PATH |
|
|
| `API key not set` | Run `hermes model` to configure your provider, or `hermes config set OPENROUTER_API_KEY your_key` |
|
|
| Missing config after update | Run `hermes config check` then `hermes config migrate` |
|
|
|
|
For more diagnostics, run `hermes doctor` — it will tell you exactly what's missing and how to fix it.
|
|
|
|
## Install method auto-detection
|
|
|
|
Hermes auto-detects whether it was installed via the git installer, Docker, or NixOS, and `hermes update` prints the matching update command for that path. There's no env var to set — the detection is based on the install layout (`~/.hermes/hermes-agent/` checkout, Docker image stamp, or Nix store path). `hermes doctor` also surfaces the detected method under its environment summary.
