使用this guide在BitBake中迈出第一步，直到运行bitbake world时，安装程序才能正常运行-

是的-我从github上获取了最新的BitBake：

bitbake --version
BitBake Build Tool Core version 1.40.0

我的python代码怎么了？

Answer 1

教程代码已损坏。 bitbake.conf存储在

中

ch04/meta-tutorial/conf/bitbake.conf

但属于

ch04/build/conf/bitbake.conf

将文件移动到该位置即可

我打开了一个问题：https://bitbucket.org/a4z/bitbakeguide/issues/17/bitbakeconf-stored-in-the-wrong-place

Answer 2

我正面临着完全相同的问题，但由于bitbake版本终于找到了它。

如果您从https://github.com/openembedded/bitbake克隆bitbake，则可以签出到早期版本：

git checkout标签/1.26.0 -b 1.26.0

然后问题解决了。

Answer 3

https://www.yoctoproject.org/docs/2.1/bitbake-user-manual/bitbake-user-manual.html#var-BB_SIGNATURE_HANDLER

似乎使用BB_SIGNATURE_HANDLER noop（默认情况下）

我通过在meta-tutorial / conf / bitbake.conf中添加BB_SIGNATURE_HANDLER定义来修复此错误

BB_SIGNATURE_HANDLER ?= "basichash"

运行bitbake时发生异常
