Bash on Ubuntu on Windowsにおけるpyenv経由でのPythonインストール

Bash on Ubuntu on Windowsにおいてpyenv経由でPythonを入れようとしたら軽くハマったのでメモ。

pyenv自体のインストールはドキュメント通りで問題無くできます。

github.com

さてさくっと入れるか。

[~] pyenv install 3.6.1

C compilerがないっぽい。gcc入れる。

[~] sudo apt-get install gcc

再トライ。

please run ./configure --enable-optimizations


/home/braitom/.pyenv/plugins/python-build/bin/python-build: 行 746: make: コマンドが見つかりません

今度はmakeがない。ですよね。ごめんなさい入れます。

[~] sudo apt-get install make

今度こそ。

zlibがないっぽい。すいません入れます。

[~] sudo apt-get install zlib1g-dev

4度目の正直。

あれ? ここで気づきました。そうだこれはUbuntuだった。

結論

ということで最初にまるっといれておけばOKです。

[~] sudo apt-get install git gcc make openssl libssl-dev libbz2-dev libreadline-dev libsqlite3-dev

教訓

Windows触ってるけどUbuntuだってことを忘れないようにしましょう。
