在执行类似操作之后，您需要知道哪个软件包失败了(并且bitbake告诉了这个问题)

You need to know what package is failing (and bitbake tells that), after that doing something like

$ bitbake -c cleansstate $PACKAGE_NAME
$ rm -fr ${DL_DIR}/git2/$REPOSITORY

(其中$PACKAGE_NAME是您的软件包名称，${DL_DIR}是local.conf中的变量(默认为build/downloads)，而$REPOSITORY是该$PACKAGE_NAME的存储库(配方中的URL))足够.

(where $PACKAGE_NAME is your package name, ${DL_DIR} is the variable from local.conf (defaults to build/downloads) and $REPOSITORY is the repository (URL from the recipe) for this $PACKAGE_NAME) should be enough.
