在 Mac Big Sur 上，如何让通过 homebrew 安装的 openssl 版本成为命令行上使用的版本？

Question

我在 Mac OS Big Sur 上。我通过 home-brew 安装了 openssl 使用

$ brew install openssl
Updating Homebrew...
==> Auto-updated Homebrew!
Updated Homebrew from 40a7a0119 to f50b87031.
Updated 2 taps (homebrew/core and homebrew/cask).

Updated 19 casks.

Warning: openssl@1.1 1.1.1l is already installed and up-to-date.

  brew reinstall openssl@1.1

Removing: /Users/davea/Library/Caches/Homebrew/openssl@1.1--1.1.1k... (5.4MB)

以上似乎暗示我已经安装了1.1.1版本，但是当我在命令行上查看时，我看到了

$ openssl version
LibreSSL 2.8.3
$ which openssl
/usr/bin/openssl

这个较新版本的 openssl 来自哪里？如何使我的机器上的版本保持一致？

您可以在 shell 中添加类似的内容，以便您的环境选择 brew 版本。

export PATH="/usr/local/opt/openssl@1/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/openssl@1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1/include"
