エラー文は以下の2つです。

ERROR: boto3 1.4.2 has requirement s3transfer<0.2.0,>=0.1.0, but you'll have s3transfer 0.3.3 which is incompatible.

試した方法

問題のライブラリをアンインストール後、再度インストールする。
```
pip3 uninstall botocore
pip3 uninstall s3transfer
pip3 install awscli --upgrade --user
```

pythonをアップデートする。

conda update python
pip3 install awscli --upgrade --user

1では無理でした。しかし、2を行うと成功しました。(ちなみに上記の2はアナコンダでpythonを管理している人しかできません)

まとめ

aws cliインストール時にライブラリに関するエラーが起きた
python本体をアップデートしたら成功した。

** python アップデートしろ💢💢💢**
