Other notes

また、手元の別 PC にて pip3 install -U online-judge-verify-helper を実行しましたが問題なくインストールされました。

インストールが成功した環境

• Mac OS Catalina 10.15.6
• pip version 20.2.3
• Python 3.8.5

lxml のバグ (https://bugs.launchpad.net/lxml/+bug/1899830) が原因のようです。
このバグは 16 時間前に報告されたもののようであり、おそらくすぐ直ると思うので、しばらく様子見したい。
いますぐ修正したい場合は .github/workflows/verify.yml の中の https://github.com/actions/setup-python で Python 3.8 を使うよう明示的に指定してください。

---

実行結果 (https://github.com/granddaifuku/library/runs/1258632370) を見る限り以下のように Python 3.9.0 が使われています。

Run actions/setup-python@v1
with:
python-version: 3.x
architecture: x64
Successfully setup CPython (3.9.0)

GitHub Actions の気分によっては Python 3.8.6 が使われる場合もある (なぜ？) ようで、その場合は成功します (https://github.com/kmyk/competitive-programming-library/runs/1258799588)

lxml の bug は Fix Released らしいのでおそらくもう解決されてる
