oj-verify が手元で動かない

[sigma425]

$ oj-verify run や単に $ oj-verify で以下の文言が出ます

` You use an old version of online-judge-tools (< 10.0.0) with online-judge-api-client, they are not compatible. Please execute:

1. Uninstall online-judge-tools and online-judge-api-client.
    $ pip3 uninstall online-judge-tools online-judge-api-client

2. Check if they are completely uninstalled. It has successfully uninstalled when the following commands say something like "not found".
    $ command oj
    oj: command not found

    $ python3 -c 'from onlinejudge.__about__ import __version__ ; print(__version__)'
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
    ModuleNotFoundError: No module named 'onlinejudge.__about__'

3. Reinstall online-judge-tools.
    $ pip3 install online-judge-tools

` しかし自分の環境では、この条件は満たしています $ oj --version online-judge-tools 10.0.3 (+ online-judge-api-client 10.0.8)

一応文言のとおりに再インストールしましたが、同じ状況です

情報: ubuntu 18.04 試してみたら oj-bundle は動きました

[kmyk]

この文言によるエラーは「古い online-judge-tools と新しい online-judge-tools が同時にインストールされてそれらが混ざったキメラが動く」ということを防ぐためのエラーです。そちらの環境では「両方が同時にインストールされているが、新しい方しか使われてない」のにエラーになっているようで、どちらかといえば誤検出です :bow:

以下を順番に実行して、出力されたログを全部貼り付けてください。

$ pip3 uninstall online-judge-tools online-judge-api-client
$ command oj
$ python3 -c 'from onlinejudge.__about__ import __version__ ; print(__version__)'
$ python3 -c 'import pathlib, sys ; print(*[path for path in sys.path if (pathlib.Path(path) / "onlinejudge").exists()] or ["not installed"])'
$ pip3 show online-judge-tools online-judge-api-client online-judge-verify-helper

(上 3 行は貼ってもらった文言のステップ 1, 2 で、下 2 行は追加の情報取得です。ホームディレクトリのユーザ名とかを漏らしたくない場合はいい感じに編集してください)

確かに最後に謎のものが表示されてますね・・・

情報提供助かります。 予想外の残り方しててちょっと驚いてます。それぞれ違う場所に複数バージョンがインストールされてると思ってたのに、なぜかまったく同じ場所にインストールされてるぽいためです。

解決策ですが、$ pip3 uninstall online-judge-tools を追加で何度か実行してみてください。$ pip3 show online-judge-tools しても 9.2.2 が表示されなくなれば成功です。 それでもだめなら、最終手段として、$ rm -rf ~/.local/lib/python3.6/site-packages/online*judge* をして関連ファイルを直接消し飛ばせば動くようになるはずです。

online-judge-tools の 9.2.2 9.2.1 7.8.0 7.2.0 online-judge-verify-helper の 4.10.1 4.9.1 が残っていて（は？）、全部消し飛ばしたあとインストールし直したら動きました！ありがとうございます。
