你自己装的flexget插件ptsites要求的python版本过高。
更具体的 这个插件使用了python 3.8的新特性 walrus 运算符，而你装的是python3.7

Python 3.9.0

[Aniverse]

脚本里用 pyenv 装了个 Python 3.7.8 给 FlexGet 使用，即便你系统的 Python 升级到了 3.9 也不影响 FlexGet 的 Python
我脚本里之前带了一组第三方插件，这个插件现在要求 Python 3.8（之前是 3.7 可以用的）
考虑到这个插件实际上用的人应该不多（我估计大多数人都不知道我顺带装了这个插件），我干脆就把这个插件去掉了
（当然我也可以选择把脚本指定的 Python 版本升级下，不过还是先不这么做好了）

现在最简单的办法就是把出错的插件删了：

rm /home/imissbanana/.config/flexget/plugins/ptsites/sites/dmhy.py

如果还不行的话干脆

rm -rf /home/imissbanana/.config/flexget/plugins/*
