サーバーレスのイベント駆動型Pythonアプリを構築及びデプロイできる「Zappa」のインストール

サーバーレスのイベント駆動型Pythonアプリを構築及びデプロイできる「Zappa」のインストールについて解説しています。

「Zappa（https://github.com/zappa/Zappa）」は、サーバーレスのイベント駆動型PythonアプリをAWS Lambda + API Gatewayを用いて簡単に構築及びデプロイできます。

■Python

今回のPythonのバージョンは、「3.8.5」を使用しています。（Windows10）（pythonランチャーでの確認）

■Zappaをインストールする

Zappaをインストールを行いますが、今回はpipを経由してインストールを行うので、まずWindowsのコマンドプロンプトを起動します。

pip install zappa

起動後、上記のコマンドを入力し、Enterキーを押します。

なお、今回は、pythonランチャーを使用しており、Python Version 3.8.5にインストールを行うために、バージョンの切り替えを行います。

py -3.8 -m pip install zappa

切り替えるために、上記のコマンドを入力し、Enterキーを押します。
