Pyenv无法安装Python2.7.7-在最后一步失败尝试安装PIP

Question

我正在尝试使用OS Monterey 12.3.1在MacBook上安装Python2.7，并具有以下命令：

$ export LDFLAGS="-L/usr/local/opt/zlib/lib -L/usr/local/opt/openssl/lib -L/usr/local/opt/sqlite/lib"
$ export CPPFLAGS="-I/usr/local/opt/zlib/include -I/usr/local/opt/openssl/include -I/usr/local/opt/sqlite/include"
$ pyenv install 2.7.7

Python2的安装似乎与PIP的安装相结合。当Pyenv试图安装PIP时，pyenv install命令在以下输出中失败：

$ pyenv install 2.7.7

似乎一切都在起作用，但是pypi.org的root证书不信任，什么都不是'这很有意义，因为我可以在浏览器中查看证书，并且表明它是值得信赖的。

我无法理解什么？如何让Pyenv完成Python2.7.7和PIP的安装？
