Arch linux：Cura thows：ValueError：使用不正确的名称调用 PyCapsule_GetPointer

当我cura在终端上输入时，出现此错误并且程序无法启动：

john@arch-thinkpad ~> cura

Original exception was:

我能做什么来解决这个问题？我已经尝试更新所有 pip 软件包，但错误仍然存​​在。

谢谢你的帮助

您是否尝试过从 master 构建 pynest2d ？它对我有用：

git clone https://github.com/Ultimaker/pynest2d
cd pynest2d
mkdir build && cd build
cmake ../
make
sudo make install

最简单的解决方案是卸载 cura 及其依赖项：

sudo pacman -Rns cura

并再次安装：

sudo pacman -S cura
