Python异常

我在运行 lightdm-gtk-greeter-settings 或编译 python 应用程序时遇到这些错误。

我可以看到它与 python 相关，但不确定需要采取哪些步骤来解决。安装了Python默认3.5（也安装了2.7）

操作系统 Manjaro XFCE（基于 Arch 64）

有人可以告诉我问题是什么吗？

谢谢

答案1

您正在针对 python 3.5 运行此代码 - 但似乎 enum 仅针对 3.4 或更早版本运行。尝试运行/usr/bin/python2.7解释器。或早期的 Python 3<= 3.4

答案2

在 Freenode 上 #python 上的 The-Compiler 的一些出色帮助下，该问题现已修复。

cd /usr/lib/python3.5/site-packages; pacman -Qo * 2>&1 | grep '^error:'

删除 site-packages 目录中列出的所有包。
