* gate on min uv version and shortcut python candidate search if known
* fix sort -V cross compat issue, run_quiet early exit on llamacpp, autolaunch
* update launch message
* Fix PR comments
* auto launch and find open port
* remove dev install
* Fix review findings: major-version guard, non-fatal port fallback, tty comment, restore local
* Remove autolaunch, clean up dead state and debug noise
- Remove find_open_port, TTY-gated autolaunch, and </dev/tty
redirection from install.sh; just print launch instructions
- Remove unused BEST_MAJOR variable from studio/setup.sh
- Remove stray "finished finding best python" debug echo
- Fix stale comment "below 3.12" to "below 3.11"
* Reject prerelease uv at exact minimum version boundary
* Remove 2>/dev/null from version_ge numeric comparisons
Let non-numeric version parts surface errors on stderr
instead of being silently swallowed.

* Fix macOS install.sh: stdin consumption and Python discovery
Two issues when running `curl | sh` on macOS:
1. Commands like `brew install` consume bytes from the piped stdin,
causing the shell to lose its place in the script. The remaining
source code gets printed as text instead of being executed, so
users have to run the installer twice. Fixed by redirecting stdin
from /dev/null for brew, apt-get, xcode-select, and the uv
installer subprocess.
2. setup.sh searches for Python 3.11-3.13 on the system PATH via
`compgen -c`. On macOS systems that only have Python 3.9 and/or
3.14, this fails with "No Python version between 3.11 and 3.13
found" even though uv already installed Python 3.13 into the
venv. Fixed by adding the venv's bin/ to PATH before invoking
`unsloth studio setup`.
* Guard PATH export against empty VENV_ABS_BIN
If cd into the venv bin/ fails, VENV_ABS_BIN would be empty and
PATH would start with ":", causing the current directory to be
searched for executables. Wrap the export in a non-empty check.
* One liner setup for unsloth studio
* Fix install scripts: system deps, activation bugs, curl/wget support
- install.sh: detect platform (macOS/Linux/WSL) and check for missing
system dependencies (cmake, git, build-essential, libcurl4-openssl-dev).
Prompt user once for permission to install all missing packages via
brew (macOS) or sudo apt-get (Linux/WSL). Add wget fallback via
download() helper since curl is not always present on minimal Linux
installs. Fix nested curl|sh stdin stealing by downloading uv installer
to a tempfile first. Replace venv activation (no-op in a pipe subshell)
with explicit --python flag for uv pip install and direct venv binary
invocation. Add idempotency guard for venv creation. Redirect stdin
on unsloth studio setup to prevent pipe consumption. On macOS, check
for Xcode Command Line Tools and trigger install if missing.
- install.ps1: wrap script body in Install-UnslothStudio function so
that errors use return instead of exit (exit kills the terminal when
run via irm|iex). Remove activate.ps1 invocation entirely -- use
explicit --python path for uv pip install and & $UnslothExe for
studio setup. This avoids both the child-scope activation bug (& vs
dot-source) and the execution policy error on default Windows systems.
Add winget availability check with clear error message. Fix PATH
refresh to append registry paths instead of replacing the session PATH.
Add uv installer fallback via astral.sh PowerShell script if winget
install does not put uv on PATH. Broaden Python version check to
accept 3.11-3.13. Add idempotency guard for venv creation.
- README.md: add wget one-liner alternative for systems without curl.
* Fix Tailwind CSS v4 .gitignore bug on Windows (#4444)
- Add .gitignore hiding workaround to setup.ps1 (matching existing
setup.sh logic) so venv .gitignore files containing "*" don't prevent
Tailwind's oxide scanner from finding .tsx source files
- Add CSS size validation to setup.sh, setup.ps1, and build.sh to catch
truncated Tailwind builds early
- Remove stray force-rebuild overrides that made the "skip build if
current" cache check dead code in both setup scripts
- Add rm -rf dist to build.sh to force clean rebuilds for wheel packaging
* Change default port 8000 to 8888, fix installer bugs, improve UX
- Change default Studio port from 8000 to 8888 across all entry points
(run.py, studio.py, ui.py, colab.py, vite.config.ts, setup scripts)
- Update launch banner: "Launching with studio venv..." to
"Launching Unsloth Studio... Please wait..."
- Add "Open your web browser" banner and rename labels
(Local -> Local Access, External -> Worldwide Web Address)
- Fix venv idempotency: check for bin/python instead of just directory
existence, clean up partial venvs on retry
- Fix build.sh CSS validation: handle empty CSS case that silently
bypassed the check with "integer expression expected"
- Fix install.sh sudo handling: try apt-get without sudo first (works
when root), then escalate with per-package tracking and user prompt
- Fix install.ps1: check exit code from studio setup, fail on error
- Add pciutils to WSL GGUF build dependencies
- Apply same smart apt-get escalation pattern to studio/setup.sh
* Use detected Python version for venv, abort on non-apt Linux
- install.ps1: detect existing Python 3.11/3.12/3.13 and use that
version for venv creation instead of always forcing 3.13
- install.sh: exit with error on non-apt Linux distros when required
packages cannot be auto-installed, instead of silently continuing
* Make sudo permission prompt more prominent with warning banner
* Add Accept [Y/n] sudo prompt to studio/setup.sh for consistency
* Fix native command exit code handling and sudo decline flow
install.ps1: Add $LASTEXITCODE checks after winget (Python), uv venv,
and uv pip install calls. $ErrorActionPreference only catches PowerShell
cmdlet errors, not native executable failures. The Python check also
handles winget returning non-zero for "already installed".
setup.sh: Skip llama-server build when user declines sudo or sudo is
unavailable. Previously the script continued to section 8 which would
fail with confusing errors (e.g. "gcc: command not found") since
build-essential was never installed.
* Move rm -rf llama.cpp inside build branch to preserve existing install
When _SKIP_GGUF_BUILD is set (user declined sudo or sudo unavailable),
the previous rm -rf would destroy an already-working llama-server before
the skip check ran. Move it inside the else branch so existing builds
are preserved when the rebuild is skipped.
