[解決済み] Windows 10にKivyをインストールする際の問題点

質問

ドキュメントの指示に従っています。 https://kivy.org/doc/stable/installation/installation-windows.html

そして、ステージにたどり着いた

Install kivy:

python -m pip install kivy==1.11.1

これ以前はすべて問題なく動作していました。pythonのバージョンとpipのバージョンを--verisonで確認しました。Python 3.8.1 と pip 20.0.2 (python 3.8)です。

まず、そのステップはうまくいかず、次のようになりました。 ERROR: Failed building wheel for kivy

そこで、いろいろ調べてみると、ホイールを直接ダウンロードできることがわかりました。そこで、ダウンロードしたのは https://kivy.org/downloads/appveyor/kivy/Kivy-2.0.0rc1.20200130.318720360-cp38-cp38-win_amd64.whl 私はpython 3.8と64ビットプロセッサを持っているので、これは正しいバージョンだろうと思いました。

しかし python -m pip install Kivy-2.0.0rc1.20200130.318720360-cp38-cp38-win_amd64.whl 次のようなエラーが発生します。

ERROR: Could not find a version that satisfies the requirement Kivy-2.0.0rc1-cp38-cp38-win_amd64 (from versions: none)
ERROR: No matching distribution found for Kivy-2.0.0rc1-cp38-cp38-win_amd64

解決方法は？

python -m pip install kivy==1.11.1 は pypi からしかダウンロードできません。python 3.8 用の whl ファイルが pypi にないためです。ソースパッケージのビルドに失敗するようですが、これにはいくつかの理由が考えられます。

さらに、インストール場所からもわかるように、（おそらく意図せず）32bitのPythonをインストールしてしまっています。 Python38-32 . そのため、あなたの whl ファイルをインストールすることはできません。 64 . 私はあなたのパイソンをアンインストールし、64ビット版を再インストールすることをお勧めします。
