Yocto 将本地 tarball 路径添加到配方问题

Question

我在为 BeagleBone Black 构建 yocto 发行版时遇到这样的问题。我正在尝试从位于以下位置的本地文件夹添加 Ninvaders 游戏（基于角色的空间游戏，用于在终端上运行以练习 yocto。）

file:///home/user/Downloads/ninvaders-0.1.1.tar.gz 我添加了一个文件夹并在食谱扩展上给出了食谱：（我知道将其放置在这里没有意义，但出于教育目的）

ninvaders.inc

DESCRIPTION = "ncurses-based clone of space invaders"

SRC_URI = "${file:///home/user/Downloads/${BP}.tar.gz"

LICENSE = ""

和 ninvaders_0.1.1.bb

require ninvaders.inc 但是当我尝试跑步时

bitbake ninvaders 它给了我这个错误：

The variable dependency chain for the failure is: do_fetch[file-checksums]

ERROR: Parsing halted due to errors, see error messages above

Summary: There were 2 ERROR messages, returning a non-zero exit code.

I cannot find any solution to this case. Could you help me? thank you.

错误消息清楚地表明您的食谱有什么问题：

Could not find a fetcher which supports the URL: '${file:///home/user/Downloads/ninvaders-0.1.1.tar.gz' 请参阅获取器的文档：

https://docs.yoctoproject.org/bitbake/2.6/bitbake-user-manual/bitbake-user-manual-fetching.html#local-file-fetcher-file

源 URI 必须采用以下格式：

SRC_URI = "file:///home/user/Downloads/${BP}.tar.gz"

但你指定了

SRC_URI = "${file:///home/user/Downloads/${BP}.tar.gz"
