在 macOS Big Sur 上使用 Homebrew 错误将 Python 3.8 降级到 3.7

如何解决在 macOS Big Sur 上使用 Homebrew 错误将 Python 3.8 降级到 3.7

我正在尝试按照指定的 Homebrew 方法 here 在 macOS Big Sur 上将 Python 3.8.2 降级到 Python 3.7.0。

但是，在执行 pyenv install 3.7.0 命令时，我遇到了如下无法解决的错误：

bash-3.2$ pyenv install 3.7.0

python-build: use openssl@1.1 from homebrew
python-build: use readline from homebrew

这种方法有什么解决方法吗？是否建议卸载 Python 3.8.2 并使用 Python 3.7.0 进行全新安装？
