MACに AWSCLIをインストールをしたら詰まったのでメモ

2019/4/7 python3.7
MACにAWS CLIをインストールしたら詰まってしまったのでメモ

###インストール

```console
$ pip install awscli --upgrade --user
```

###インストール確認

```console
$ aws --version
-bash: aws: command not found
```

実行できなかった。
ドキュメントによるとpythonのあるディレクトリにインストールされるのでパスを通せとあるが、インストールされていなかった。
調査した結果pip show _パッケージ_でインストールしたパッケージの場所を確認できるとあったので確認。

```console
$ pip show awscli
Name: awscli
Version: 1.16.140
Summary: Universal Command Line Environment for AWS.
Home-page: http://aws.amazon.com/cli/
Author: Amazon Web Services
Author-email: UNKNOWN
License: Apache License 2.0
Location: ＄HOME/.local/lib/python3.7/site-packages
Requires: rsa, botocore, PyYAML, colorama, s3transfer, docutils
Required-by: 
```

確認した場所をbash_profileに追加後bash_profile読み直し

```sh
$HOME/.local/lib/python3.7/site-packages/shims:$PATH
source ~/.bash_profile
```

しかし、解決しなかった。インストール時のログを見直したら/Users/_ユーザ名_/.local/binとあったのでそこにパスを通したら解決した。なぜそこにインストールされたか不明わかる人教えてください。

```console
$ pip install awscli --upgrade --user

pip のオプションに --user をつけるとsite.USER_BASEにインストールされるらしい。
site.USER_BASEの確認方法は下記の通り。

```python
import site
site.getuserbase()
'＄HOME/.local'
```
