COPY --from=builder /opt/uv/uv /usr/local/bin/uv
COPY --from=builder /root/.local/share/uv/python /root/.local/share/uv/python

# 3. 核心修复：在最终镜像中用正规的 npm 安装 opencode-ai，确保系统全局软链接生成完整
RUN npm install -g opencode-ai && npm cache clean --force

# 4. 精准寻找 uv 的 Python 路径并建立全局 python / python3 软链接（消除通配符失败隐患）
RUN UV_PYTHON_BIN=$(ls /root/.local/share/uv/python/cpython-3.11.*/bin/python3 | head -n 1) \

    && ln -s /usr/local/bin/python3 /usr/local/bin/python

# 5. 验证成果
