Answer 1

argparse现在是Python2和Python3的一部分，但是subliminal依赖于python3-stevedore，这个包包含requires.txt中的条目argparse。您可以通过以下方法来检查：

• 生动猫/usr/lib/python3/dist-packages/stevedore-1.3.0.egg-info/requires.txt
• 狡猾的猫/usr/lib/python3/dist-packages/stevedore-1.5.0.egg-info/requires.txt

解决方案是一个肮脏的黑客，删除这一行：

• 生动的sudo sed /usr/lib/python3/dist-packages/stevedore-1.3.0.egg-info/requires.txt /sed -i.bak /d‘-i.bak
• 巧妙地支持sed -i.bak‘/sed-i.bak/d’-i.bak

对于仿生(18.04)以上作品，但考虑到装载机版本较高。它可以通过以下方式进行检查：

ls -l /usr/lib/python3 3/dist-packages/

然后搜索stevedore-*文件夹。就我而言：

sudo sed -i.bak‘/sed-i.bak/d’-i.bak

Answer 2

只需做：

pip3 install --user subliminal stevedore==1.19.1 

通过apt安装潜意识后，以修复装载机版本。这将覆盖系统版本。
