bitbake 在最简单的食谱上失败了

Question

刚刚安装Yocto。在morty 分支上。执行了以下命令：

cd poky
source oe-init-build-env build-qemuarm

在conf/local.conf把机器名改成MACHINE ?= "qemuarm"

然后执行以下操作：

$ bitbake core-image-minimal

看起来这是一个python 错误。有谁知道是什么问题？是不是我用错版本了？

这是python --version的输出

$ python --version
Python 2.7.12

我做错了什么？

你知道莫蒂已经 18 个月大了，几周后就会得到更长的支持，对吧？

无论如何，看起来sstate-cache/ 不知何故损坏了。删除您的tmp/ 和sstate-cache/ 目录，然后重试。
