zlibが使えないと言われるが、brewでzlibとかは諸々入れている
公式のWikiには、additionalなSDK headerをインストールせよと書いてあるが、 Home · pyenv/pyenv Wiki · GitHub
$ sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target / installer: Error - the package path specified was invalid: '/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg'.
と言われる。それはそうで、
$ ls /Library/Developer/CommandLineTools/
Library SDKs usr
Packagesなど無い
解決法
SDK headerが無いので、includeする
fishなら
$ set -x CFLAGS -I(xcrun --show-sdk-path)/usr/include
bashとかなら
$ export CFLAGS="-I$(xcrun --show-sdk-path)/usr/include"
をしてからpyenv install 3.7.3をすれば良い
