答案不仅适用于 Ubuntu 18.04、Bionic，也适用于任何pip已安装的版本

这个问题似乎是最新的 pythonstevedore包和之间的不兼容guessit，正如Debian 错误报告日志中所报告的那样

解决方案是stevedore从PyPi Repository安装适当的版本，以便做到这一点

• 使用以下命令卸载您从 apt 获得的现有软件包 sudo apt-get purge -y python3-stevedore
• 使用适当版本的 stevedore 安装 PyPi 版本的 subliminal sudo pip3 install subliminal stevedore==1.19.1

现在subliminal从终端运行将让它像往常一样运行：
