pip install -r requirements.txt bug

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Happens on both the portable and CLI install. I have Miniconda installed in path in my User account.

### Other

:(

Bắt đầu với requirements.txt, đặc biệt là mục sentencepiece được ghi chú ở dòng 12, và tái hiện pip install -r requirements.txt trên Windows trong cả thiết lập portable và CLI. Kiểm tra lỗi của sentencepiece setup.py và xem subprocess cmake có khả dụng hay không; hoàn tất có nghĩa là các dependency được cài đặt thành công mà không gặp lỗi tạo metadata.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
