gnuradio 启动错误 Couldn‘t find foreign strtct converter for ‘cairo.Context‘_failed to initialize gtk. if you are running over

INFO

• OS：Linux 6.1.1-arch1-1
• gnuradio：3.10.4.0-2

弹窗错误的标题为 ImportError,内容为“Failed to initialize GTK. If you are running over ssh, did you enable X forwarding and start ssh with -X?(Couldn’t find foreign strtct converter for ‘cairo.Context’)”

从终端尝试获取更多错误细节

$ gnuradio-companion

此时启动没有 gtk 模块缺失的问题了，但是弹窗错误还在。最后通过搜索发现缺的是一个 python 包，在仓库里却找不到 python3-gi-cairo，最后通过排列组合找到了 python-cairo。这下子总算可以启动了

solution

sudo pacman -S kde-gtk-config
sudo pacman -S python-cairo
