我在安装了最新的xcode的Catalina

$/usr/bin/xcodebuild -version
Xcode 12.4
Build version 12D4e

gcc看起来很合理：

$which gcc
/usr/bin/gcc

$gcc -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1

以下是有关信息clang：

$which clang

更新这里有一些错误config.log：有关于clang的投诉：

clang: error: argument to '-V' is missing (expected 1 value)
clang: error: no input files
configure:3880: $? = 1

clang: error: unknown argument '-qversion'; did you mean '--version'?

...

请注意，我已经查看了PyEnv BUILD FAILED installed Python on MacOS的答案。例如，我尝试了以下操作：

export SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk
export MACOSX_DEPLOYMENT_TARGET=10.15
pyenv install 3.8.8

但它以同样的方式失败了。我还应该检查什么以及如何解决？
