Word,PowerPoint,PDFなどからテキストを抽出できる「textract」のインストール

Word,PowerPoint,PDFなどに埋め込まれた情報（テキスト）を抽出できる「textract」のインストールについて解説しています。

「textract（https://github.com/deanmalmgren/textract）」は、Word,PowerPoint,PDFなどの各形式から、無関係なマークアップなしでコンテンツを抽出できるPythonライブラリです。

■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）

■textractをインストールする

textract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 textract

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 textract

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。

WARNING: There was an error checking the latest version of pip.

Enterキーを押すと、インストールが開始され、上記のように「Successfully installed」と表示されます。これが表示されれば、textractが正常にインストールされたことになりますが、今回は「ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.（ERROR: pip の依存性解決は現在インストールされているすべてのパッケージを考慮に入れていません。この挙動は以下のような依存関係の衝突の原因となっています。）」や「which is incompatible.（これは互換性がありません。）のエラーが出力してしまいました。このため、インストールする際は、こちらとしては仮想環境の構築を行い、インストールすることを推奨します。

なお、今回はtextractのバージョン1.6.5をインストールしました。
