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。
