我試圖通過引用this使用yocto構建樹莓派3的圖像，同時運行bitbake命令我收到以下錯誤。 「：類型錯誤：getVar（）至少需要3個參數（2給出）異常」解析錯誤，同時構建樹莓派3的圖像使用yocto
在錯誤日誌中，它在執行一個Python函數，但是沒有錯誤的細節，我可以看到異常說錯誤。但在很多地方我可以看到，getVar只有兩個參數。
你能指導解決這個問題。我可以看到d.getVar（）很多地方，你能告訴我這裏是什麼，我在yocto文檔中搜索，但沒有找到任何解釋什麼是d的信息。

getVar函數{getVar（var，d，exp = False）}在data.py（available @ bitbake/lib/bb）中定義，它在內部調用{d.getVar（var，exp）}。我在bb文件中添加了「導入數據」，但它在導入語句時給出瞭解析錯誤。同樣的問題，當我嘗試添加inc文件也。你能幫助如何在「meta-raspberrypi」圖層中導入這個data.py。 – Ravi
