MoneyPrinterV2 实战指南:使用 Gemini API 自动生成 YouTube Shorts

## 环境准备清单

- [ ] Python 3.12 已安装
  ```bash
  python --version  # 确认输出 Python 3.12.x

### 如何找到你的 Firefox Profile 路径

```bash
# macOS
ls ~/Library/Application\ Support/Firefox/Profiles/
# 找到 xxxxx.default-release 那个目录，完整路径就是 Profile 路径
# 例如：/Users/你的用户名/Library/Application Support/Firefox/Profiles/xxxxx.default-release

git clone https://github.com/FujiwaraChoki/MoneyPrinterV2.git
cd MoneyPrinterV2

# 创建虚拟环境
python -m venv venv

# macOS / Linux 激活
source venv/bin/activate

# Windows 激活
# .\venv\Scripts\activate

pip install -r requirements.txt

# 现象：ModuleNotFoundError: No module named 'selenium.webdriver.firefox.firefox_binary'
# 原因：selenium_firefox 包依赖的 firefox_binary 模块在 Selenium 4.40+ 中被移除

pip install selenium==4.39.0

# 现象：ImportError: cannot import name 'editor' from 'moviepy'
# 原因：MoviePy 2.x 移除了 editor 模块，而 YouTube.py 中大量使用 from moviepy.editor import *

pip install 'moviepy<2'

# 验证 Selenium 版本
pip show selenium | grep Version
# 期望输出：Version: 4.39.0

# 验证 MoviePy 版本
pip show moviepy | grep Version
# 期望输出：Version: 1.0.3

# 验证 litellm 已安装
pip show litellm | grep Version

## 改动总结

### 核心改动
- [x] 将 Ollama 本地 LLM 替换为 Gemini API（通过 litellm）
- [x] 重写 llm_provider.py，支持自动重试 + 模型降级
- [x] 配置使用 Gemini Imagen 4.0 生成图片

### Bug 修复
- [x] Selenium 降级到 4.39.0（修复 firefox_binary 导入错误）
- [x] MoviePy 降级到 1.0.3（修复 editor 模块缺失错误）

### 零改动
- [x] YouTube.py — 无需修改，接口兼容
- [x] Twitter.py — 无需修改，接口兼容
- [x] TTS 模块 — 本地运行，不涉及 API
- [x] Whisper 字幕 — 本地运行，不涉及 API
