mac m1上使用rust编译openssl-sys失败的一次记录

mac m1 编译openssl-sys的时候报错：

遇到错误，报错信息如下

  Could not find directory of OpenSSL installation, and this `-sys` crate cannot
  proceed without this knowledge. If OpenSSL is installed and this crate had
  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
  compilation process.

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl
  and include information about your system as well as this message.

同样的代码在ubuntu上正常，但是在mac m1上面无法编译，根据报错信息所以猜测是openssl-sys这个库需要调用本机上的openssl,但是无法找到。
找到了一篇文档，
https://reality0ne.com/macos-xia-shi-yong-rust-openssl/

执行文章中的命令：

$ cargo clean
$ export OPENSSL_LIB_DIR=$(brew --prefix openssl)/lib
$ export OPENSSL_INCLUDE_DIR=$(brew --prefix openssl)/include
$ cargo build
$ cargo test

然后到项目里面cargo run一下，仍然报错

这个提示大概看懂了，意思是openssl的库在/opt/homebrew/opt/openssl@3/lib下不存在，cd到这个目录之后发现确实不存在

admin@admindeMacBook-Air opt % ls
pkg-config      pkgconfig

所以打算用homebrew重新安装一下，这里使用了这个作者的方法
https://zhuanlan.zhihu.com/p/111014448 （homebrew国内镜像安装）
然后执行brew install openssl

执行过程：

admin@admindeMacBook-Air opt % brew install openssl
Error: 
  homebrew-core is a shallow clone.
  homebrew-cask is a shallow clone.
To `brew update`, first run:
  git -C /opt/homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
  git -C /opt/homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow
These commands may take a few minutes to run due to the large size of the repositories.
This restriction has been made on GitHub's request because updating shallow
clones is an extremely expensive operation due to the tree layout and traffic of
Homebrew/homebrew-core and Homebrew/homebrew-cask. We don't do this for you
automatically to avoid repeatedly performing an expensive unshallow operation in
CI systems (which should instead be fixed to not use shallow clones). Sorry for
the inconvenience!
