メモ：Boto3でエラー -> upgradeで解消(多分)

課題： UbuntuにBoto3を入れたがエラーが出て動かない
結論：関連ライブラリを更新することで解消(多分)

以下が発生したエラー

>>> import boto3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.8/dist-packages/boto3/__init__.py", line 17, in <module>

    from botocore.httpchecksum import handle_checksum_body
  File "/usr/local/lib/python3.8/dist-packages/botocore/httpchecksum.py", line 36, in <module>
    from awscrt import checksums as crt_checksums
ImportError: cannot import name 'checksums' from 'awscrt' (/usr/local/lib/python3.8/dist-packages/awscrt/__init__.py)

以下の手順で関連ライブラリを最新版に更新*1

sudo python -m pip install --upgrade awscrt
sudo python -m pip install --upgrade awsiotsdk

エラーは解消

>>> import boto3

*1:root権限で入れるな、VirutalEnvを使えと怒られる(System Package Managerの矛盾を引き起こすリスク)ので、多分良くない操作と思う
