くさるほど溢れてますが自身の備忘録を兼ねて。
インストールと初期セットアップのみです。入れてなにかやるとかはないです。

Poetryのインストール

インストール

READMEに従ってインストールします。

sdispater/poetry #Installation 🔗

$ curl -sSL https://raw.githubusercontent.com/sdispater/poetry/master/get-poetry.py | python
Retrieving Poetry metadata

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

$HOME/.poetry/bin

This path will then be added to your `PATH` environment variable by
modifying the profile files located at:

$HOME/.profile
$HOME/.bash_profile

You can uninstall at any time with `poetry self:uninstall`,
or by executing this script with the --uninstall option,
and these changes will be reverted.

Installing version: 0.12.17
  - Downloading poetry-0.12.17-darwin.tar.gz (7.38MB)

Poetry (0.12.17) is installed now. Great!

To get started you need Poetry's bin directory ($HOME/.poetry/bin) in your `PATH`
environment variable. Next time you log in this will be done
automatically.

To configure your current shell run `source $HOME/.poetry/env`

このままコマンドを実行してもcommand not foundになります。

$ poetry
-bash: poetry: command not found

PATHを通す

コマンドを使えるようにするためにPATHを通します。

$ echo '$HOME/.poetry/bin:$PATH' >> ~/.bashrc
$ source ~/.bashrc

これでコマンドが実行できます。

$ poetry
Poetry 0.12.17

Poetryの初期セットアップ

virtualenvの生成パスをプロジェクトディレクトリに変更

Poetryの初期状態だと~/Library/Caches/pypoetry/virtualenvs配下に書くプロジェクトの仮想環境が作成されるようなんですが
よくわからないところに作成されるのが気持ち悪いので、プロジェクトディレクトリに作成されるよう変更します。

$ poetry config --list
settings.virtualenvs.create = true
settings.virtualenvs.in-project = false
settings.virtualenvs.path = "/Users/{user}/Library/Caches/pypoetry/virtualenvs"
repositories = {}

設定を変更

$ poetry config settings.virtualenvs.in-project true

変更確認

$ poetry config --list
settings.virtualenvs.create = true
settings.virtualenvs.in-project = true
settings.virtualenvs.path = "/Users/{user}/Library/Caches/pypoetry/virtualenvs"
repositories = {}

以上

Poetryの入力補完設定

Poetryには入力補完機能があるようなので設定します。
READMEにも書いてあります。

が…有効化できませんでした。なんででしょうかね。
brewのシンボリックリンク周りな気がするんですけどよくわかりません。

$ poetry completions bash > $(brew --prefix)/etc/bash_completion.d/poetry.bash-completion

そのうちできたら追記します〜
