タイトルの通りanyenv環境下で pyenv install できずに少し詰まったのでメモ

環境

macOS Mojave 10.14.3
anyenv 1.0.1
pyenv 1.2.9

現象

$ pyenv
pyenv 1.2.9-16-g9baa6efe
Usage: pyenv <command> [<args>]

Some useful pyenv commands are:
   commands    List all available pyenv commands
   local       Set or show the local application-specific Python version
   global      Set or show the global Python version
   shell       Set or show the shell-specific Python version
   rehash      Rehash pyenv shims (run this after installing executables)
   version     Show the current Python version and its origin
   versions    List all Python versions available to pyenv
   which       Display the full path to an executable
   whence      List all Python versions that contain the given executable

$ pyenv install -l
pyenv: no such command `install'

上記の通りinstall, uninstallコマンドが使えない状態に

解決策

anyenv install pyenv 時に python-build が実行されていなかったため、以下を実行

$ ~/.anyenv/envs/pyenv/plugins/python-build/install.sh

結果

正常に使えるようになりました。
