很多同学这里就会卡住，所以还是要仔细看看报错的日志，这里说 c-ares 找不到，那换个思路，先 brew install c-ares，发现成功了。
虽然没仔细看过 brew 的代码，但是根据这两处日志，判断我采用的 brew 的源中没有 aaceeec0b1184157ff8b0ff3c53d655d0685ea37ba254ebbcb9e2d97dddea377--c-ares-1.18.1.arm64_big_sur.bottle.tar.gz 这个包，但是有 node 的包，而在下载的过程中，一般来说遇到 domain，也就是源不存在的包，可能会降级到默认的 domain，可能是国外的源，但是这里安装 node 的时候已经选定了我设置的源，所以找 c-ares 的时候没找到，但是没有直接给降级到默认的 domain，所以这里存在我直接 brew install c-ares 成功，但是通过 brew install node 来安装 libuv 失败了。
最后 libuv 安装成功后，重新执行一下 brew install node 问题就解决了。
