bitbake - 无法连接到Bitbake服务器

Question

我正在尝试设置bitbake工具并尝试按照教程进行操作

https://www.yoctoproject.org/docs/1.8/bitbake-user-manual/bitbake-user-manual.html#bitbake-examples

现在，当我运行bitbake命令时，出现以下错误，

p@p-ubuntu:~/ba/bitbake$ bitbake
NOTE: Retrying server connection... (Traceback (most recent call last):
  File "/home/p/ba/bitbake/lib/bb/main.py", line 428, in setup_bitbake
    topdir, lock = lockBitbake()
  File "/home/p/ba/bitbake/lib/bb/main.py", line 480, in lockBitbake
    lockfile = topdir + "/bitbake.lock"
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'
)

如何启动位烘烤服务器？

我严格取消了Bitbake进程(ctrl-c)之后，遇到了同样的问题。

在删除构建文件夹中的文件 bitbake.lock 之后，bitbake再次按预期工作。

rm bitbake.lock
