atcoder-toolsでsubmit時に「AttributeError」が出る対策

概要

atcoder-toolsでpython3コードのsubmit時に「AttributeError: 'NoneType' object has no attribute 'get'」というエラーが出た場合の対策です。
atcoder-tools gen でも出るかもしれません。

Traceback (most recent call last):
  File "/usr/local/bin/atcoder-tools", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.7/site-packages/atcodertools/atcoder_tools.py", line 64, in main
    exit_program(submit_main(prog, args))
  File "/usr/local/lib/python3.7/site-packages/atcodertools/tools/submit.py", line 174, in main
    metadata.problem.contest, metadata.problem, metadata.lang, source)
  File "/usr/local/lib/python3.7/site-packages/atcodertools/client/atcoder.py", line 179, in submit_source_code
    "option", text=lang_option_pattern).get("value")
AttributeError: 'NoneType' object has no attribute 'get'

手順

1. atcoder-toolsのインストール先を特定

pip3 show atcoder-tools | grep Location
# -> Location: /usr/local/lib/python3.7/site-packages

2. atcoder-toolsのソースコードを修正
   atcodertools -> common -> language.py をエディタで開き、以下の通り修正する

diff --git a/language.py b/language_old.py
