v1.1.1 — Tkinter Setup Bugfix

ComfyUI Portable Installer v1.1.1

Bug Fixes

• Fix tkinter setup SyntaxError on install (#2) — %~dp0 always returns a path with a trailing backslash (e.g. L:\comfyui-portable-installer\). When embedded in a Python raw string literal r'%SCRIPT_DIR%', the trailing \ escaped the closing quote, producing SyntaxError: unterminated string literal. Fixed by appending . so the path resolves identically without breaking the string.

v1.1.0 — REST API, External ComfyUI Support & Bugfixes

ComfyUI Portable Installer v1.1.0

New Features

• REST API server — 34-endpoint aiohttp API exposing full GUI functionality (install, instances, models, nodes, settings, jobs). Start with launcher.bat api
  • Long-running operations return HTTP 202 + job ID for async polling
  • WebSocket log streaming at /api/ws/logs
• External ComfyUI support — Target any existing ComfyUI installation via Browse or --comfyui-dir, with path persistence in settings
• Model path cross-referencing — Auto-generated module_model_paths.yaml shares model directories across multiple ComfyUI installs
• Model download API extended — POST /api/models/download now accepts direct HuggingFace model info (repo, filename, folder) in addition to registry IDs, so search results can be downloaded directly
• Centralized log tab — Tag filtering and color-coded log output in the GUI
• Faster GUI startup — Deferred initialization for snappier launch
• Package list caching — VenvManager caches installed packages for faster dependency checks

Bug Fixes

• Fix install.bat failing on fresh installs (#1) — PowerShell multi-line commands had ^ caret characters inside double quotes, causing CMD to pass them literally to PowerShell instead of treating them as line continuations. All download steps (Python, Git, FFmpeg) and the ._pth configuration were affected.
• Fix pip install failing for multi-package strings — install_package() in both VenvManager and PythonManager passed the package parameter as a single quoted argument to pip. When called with "torch torchvision torchaudio", pip treated the entire string as one package name and failed. This broke install_pytorch_cuda() on fresh installs.
• Fix GPU instance start crash via API — CUDA_VISIBLE_DEVICES received an integer when the API payload used "gpu_device": 0 instead of "gpu_device": "0". Environment variables must be strings on Windows, causing a TypeError. Added str() cast at both the API boundary and the consumer.
