如何解决在具有Intel芯片和Big Sur的MacBook Pro上安装Python < 3.7时出现的`pyenv`问题？

Question

pyenv 在搭载 Intel 芯片和 Big Sur 操作系统的 MacBook 上存在问题。

以下为我的系统信息：

$ brew --version
3.2.2

$ brew list
==> Formulae
autoconf    gdbm        mpdecimal   pkg-config  python@3.9  sqlite      xz
bzip2       m4      openssl@1.1 pyenv       readline    tcl-tk      zlib

$ xcodebuild -version
Xcode 12.5.1
Build version 12E507

$ xcode-select -version
xcode-select version 2384.

$ sw_vers
ProductName:    macOS
ProductVersion: 11.4
BuildVersion:   20F71

尝试安装不同版本的pyenv时会发生以下情况：

$ pyenv install 3.9.6   # Success
$ pyenv install 3.8.11  # Success
$ pyenv install 3.7.11  # Success
$ pyenv install 3.6.14  # Error
python-build: use readline from homebrew
python-build: use zlib from xcode sdk

BUILD FAILED (OS X 11.4 using python-build 20180424)

我尝试使用一些在GitHub问题讨论中找到的建议来修复它，但似乎都没有起作用。

rrlamichhane，有什么进展吗？虽然我的构建是最新更新的，但我也遇到了同样的问题。我尝试了所有我找到的建议，但似乎没有任何作用。 - Higor Rossato

很遗憾，我还没有找到任何解决方案。我一直在使用Python版本> 3.7。 - rrlamichhane

我在使用brew和pyenv安装Python 3.7.6时遇到了同样的问题。 运行以下命令解决了这个问题： CFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix bzip2)/include -I$(brew --prefix readline)/include -I$(xcrun --show-sdk-path)/usr/include" LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix readline)/lib -L$(brew --prefix zlib)/lib -L$(brew --prefix bzip2)/lib" pyenv install --patch 3.7.6 < <(curl -sSL https://github.com/python/cpython/commit/8ea6353.patch\?full_index\=1)
