目的・経緯

wordcloudを使いたかったので私用PCにPythonを入れて試そうとしたらハマった
何も考えずにPythonは最新のものを使用した（ここがハマったポイント）

前提条件・利用環境

Windows 11 Home 22H2(64bit)
Python 3.11.1-amd64.exe

発生事象

pip install wordcloudでエラーが発生
- 最初のエラーはVisual Studioがインストールされてない
  - この件の解決策はこの記事を参考に解決
- Visual Studioインストール後に再度試したところ、以下のエラーが発生

C:\Users\asanok>pip install wordcloud

Installing collected packages: wordcloud
  DEPRECATION: wordcloud is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

エラー箇所：
- wordcloud/query_integral_image.c(196): fatal error C1083: include ファイルを開けません。'longintrepr.h':No such file or directory
- エラー内容を検索の結果、この記事でPython3.11ではなく3.9を入れれば問題が回避できると判明
当面の目標であるwordcloudが動けば、最新のPython3.11である必要はなかったためこのままwordcloudを使用することにした

まとめ・注意事項

wordcloudを使うためにVisual Studio（「C++によるデスクトップ開発」のコンポーネント）が必要
同様に、現時点ではwordcloudはPython3.11では動作しない模様
一時的な回避策としてPython3.9をインストールすることでwordcloudが問題なく動作した
