macOS Mojave: pyenvでPython 3.7.2インストールのトラブルメモ

前提

• macOS Movave 10.14.2
• Xcode CommandLine Tools
  • $ xcode-select --install 済
• Homebrew 2.0.2
• pyenv 1.2.9

やりたいこと: Python本体のインストール

$ pyenv install 3.7.2

結論

1. もしHomebrewの binutils をインストールしていたら、削除しておく

• brew install binutils したときに次のように言われる:
  • because Apple provides the same tools and binutils is poorly supported on macOS.
• Homebrew版のbinutilsは削除して、Appleのbinutilsを使用する。

$ brew uninstall binutils

2. zlibを手動でインストールする

参考: [MacOS Mojave]pyenvでpythonのインストールがzlibエラーで失敗した時の対応 - Qiita

xcode-selectの最新バージョン(2354)にMojave用のmacOS SDK headerがデフォルトで入っていないのが原因のようです。

マニュアルで以下をインストールする必要ある:

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

以上でインストールできました。
