Arch linux：Cura thows：ValueError：PyCapsule_GetPointer 以不正確的名稱呼叫

當我cura在終端上鍵入時，出現此錯誤並且程序無法啟動：

john@arch-thinkpad ~> cura

Original exception was:

我能做些什麼來解決這個問題？我已經嘗試更新所有 pip 包，但錯誤仍然存在。

謝謝你的幫助

最簡單的解決方案是解除安裝帶有依賴項的cura：

sudo pacman -Rns cura

並再次安裝：

sudo pacman -S cura

您是否嘗試過從 master 建構 pynest2d？它對我有用：

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