# 第一阶段：强制安装完整依赖链
FROM python:3.9-slim AS builder

# 1. 更新CA证书并安装系统工具
RUN apt-get update && apt-get install -y \
    ca-certificates \  # 修复HTTPS证书问题
    && rm -rf /var/lib/apt/lists/*

# 2. 安装核心依赖（包含git）
RUN apt-get update && apt-get install -y \
    ffmpeg libsndfile1 git \
    && rm -rf /var/lib/apt/lists/*

# 3. 构建OpenVoice（此时git已可用）
WORKDIR /app
COPY OpenVoice/ ./OpenVoice
RUN pip install numpy==1.22.0 && \
    pip install -e ./OpenVoice


# 第二阶段：继承所有依赖
FROM python:3.9-slim
COPY --from=builder /usr/bin/git /usr/bin/git  # 显式复制git二进制文件
COPY --from=builder /app/OpenVoice /app/OpenVoice
COPY --from=builder /usr/local/lib/python3.9/site-packages /usr/local/lib/python3.9/site-packages

# 安装主程序依赖
