Pyenv 用

brew install pyenv 

安装好后

然后

pyenv install 3.9.0 

报错如图：

尝试 head 版本，依然报错

以前用 catalina 没这问题，升级 big sur 后一直编译失败，尝试 3.7.6

尝试重新安装 zlib

$ brew install zlib $ export LDFLAGS="-L/usr/local/opt/zlib/lib"  $ export CPPFLAGS="-I/usr/local/opt/zlib/include 

依然报错。

尝试直接 brew 安装 Python 3.9，成功。说明编译工具没问题，是 pyenv 的问题，目前有大佬知道怎么解决吗？ pyenv 对我来说蛮重要的
