ZeroClaw Reflex UI
完整搭建流程
ZeroClaw Gateway + LM Studio + Reflex 本地 AI 管理面板
前言：为什么要给 ZeroClaw 做 Web UI？
ZeroClaw 是一个用 Rust 编写的高性能本地 AI 网关工具，设计目标是速度快、体积小、无依赖。但它本身只有命令行界面（CLI），每次使用都需要手动输入命令，管理起来不够直观。
本文记录了从零开始，用 Python Reflex 框架 为 ZeroClaw 打造一个现代化 Web 管理面板的完整过程，包括踩过的所有坑和最终解决方案。
Python Reflex 框架
GitHub - reflex-dev/reflex: Web apps in pure Python
| 组件 | 说明 |
|---|---|
| ZeroClaw | Rust 编写的本地 AI 网关，提供 /webhook HTTP 接口 |
| LM Studio | 本地大模型运行环境，提供 OpenAI 兼容 API |
| Reflex | Python 全栈 Web 框架，前后端均用 Python 编写 |
| llama.cpp | 底层推理引擎（可选） |
第一步：环境准备
1.1 安装依赖
在 ZeroClaw 项目根目录，激活虚拟环境后安装所需 Python 包：
# 激活虚拟环境（Windows PowerShell）
.venv\Scripts\Activate.ps1
# 安装依赖
pip install reflex psutil python-dotenv requests pywin32
1.2 初始化 Reflex 项目
mkdir zeroclaw-reflex-ui
cd zeroclaw-reflex-ui
reflex init # 选择模板 0（空白）
⚠️ Reflex init 会生成同名的 Python 包目录和入口文件，注意不要覆盖错位置。
1.3 放置主文件
将我们编写的 zeroclaw_reflex_ui.py 覆盖到 Reflex 自动生成的同名文件：
# Windows 命令
move zeroclaw_reflex_ui.py zeroclaw_reflex_ui\
# 提示覆盖时选 Yes（Y）
