编译 openwrt 的时候出现了报错，不知道怎么解决，求问

我打算单独编译一个 ipk ，但是编译的过程中报了下面的错误，谷歌了很久，没有找到解决办法，希望有大哥能指点一下。

报错代码如下：
can't open file '/home/openwrt/build_dir/target-aarch64_cortex-a53_musl/linux-armvirt_64/linux-5.4.111/.config' at /home/openwrt/scripts/kconfig.pl line 32.

最终还是找到了解决办法，需要先编译一下内核：make target/linux/compile V=99 然后再编译单独的 ipk 插件
