aws-cliのバージョンをアップグレードする。Mac OS

気がつくとバージョンが上がっているaws-cliコマンド。
あまりにも頻繁に上がっているので、気が付いたら(向いたら？)バージョンアップを行うようにしています。
今回見たらバージョン1.10.6となっていました。とりあえず気が向いた(付いた？)のでアップグレードを行おうと思います。
ちなみにaws-cliのバージョンについては以下から確認できます。
https://github.com/aws/aws-cli

また、今回行っている環境はMac OS X El Capitainです。

# ①バージョンの確認

```bash:コマンド
$ aws --version
aws-cli/1.9.20 Python/2.7.10 Darwin/15.3.0 botocore/1.3.20
```

_aws-cli_のところを見ると_1.9.20_となっているのがわかります。
現時点(_2016-02-19_)での最新バージョンは_1.10.6_でした。
https://github.com/aws/aws-cli

# ②アップグレード

それではアップグレードを行いたいと思います。

```bash:コマンド
$ sudo pip install --upgrade awscli

なにやらエラーが発生。。。どうやらsix 1.4.1があることが原因らしい。

対応方法はいろいろありますが、今回はsixを無視してアップグレードする対応を行います。

```bash:コマンド
$ sudo pip install --upgrade awscli --ignore-installed six

無事アップグレードできました。
念のためawsコマンドでバージョンを表示します。

```bash:コマンド
$ aws --version
aws-cli/1.10.6 Python/2.7.10 Darwin/15.3.0 botocore/1.3.28
```

最新のバージョンになっているのが確認できました。
