當我設定 python 虛擬環境并安裝 hid 模塊時，它似乎無法找到我用 MacPorts 安裝的庫。我正在運行 Mac OS Big Sur 11.6.1 并且我還使用 MacPorts 安裝了 python。任何故障排除想法？

更新：hidapi 與 MacPorts 一起安裝：

您的虛擬環境中的解釋器應該與您機器上的依賴項隔離（在某種程度上），因此從這個意義上說，它按設計作業。
在匯入 python 之前檢查Set LD_LIBRARY_PATH。這應該能讓你繼續前進。

所以你的問題實際上不是你的python找不到hid包。
匯入時hid，hid嘗試加載未安裝的本機庫。這可以解決（在 MacOS 上）使用這里brew install hidapi
