FFvideo->錯誤：命令“ gcc”失敗，退出狀態為1

Question

在Docker上運行python3.6容器

嘗試“ pip install ffvideo”並捕獲“錯誤：命令'gcc'失敗，退出狀態為1”

真的不能弄清楚問題出在哪里

這是完整的錯誤文本：

這是Dockerfile的一部分

已安裝的軟件包-python-dev python3-dev apt-utils cython libavutil-dev libavcodec-dev libavformat-dev libswscale-dev

有什么想法怎么辦？

Answer 1

多虧了hoefling， r_frame_rate在Libav中早已消失，用法應改為avg_frame_rate

Answer 2

首先下載ffvideo

  pip download ffvideo
    tar -xf FFVideo-0.0.13.tar.gz

    cd FFVideo-0.0.13
    python setup.py install
