Pythonエンコーディングの問題のため、aptを使用できません。

Pythonエンコーディングの問題のため、aptを使用できません。

aptまたはaptitudeを使用して何かをインストールまたは更新しようとするたびに、Python Unicodeエラーが発生してシステムを更新できません。

私が受け取るエラーは次のとおりです。

File "/usr/bin/py3clean", line 4
SyntaxError: Non-ASCII character '\xc2' in file /usr/bin/py3clean on line 4, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

私はリンクをたどり、Pythonエンコーディングのためのマジックコメントを設定することについて話しましたが、それは確かに正しい方法ではありませんでした。マジックコメントを手動で追加してエラーをバイパスすることができましたが、py3clean他のPythonファイルで問題が報告されました。

私はPythonユーザーではないので、心配しています。 Pythonエンコーディングを制御するために設定できるシステム全体の変数はありますか?それとも別の方法で問題を解決できますか?

私はDebianを使って3.16.0-4-686-pae#1 SMP Debian 3.16.7-ckt4-3(2015-02-03)i686 GNU / Linuxをテストしています。

ありがとうございます。

U&Lチャットルームでポスターとしばらく会話をした後、これがPython問題、特にコーディング問題であることが明らかになりました。問題は、ポスターのPython 3がスクリプトでutf8文字を正しく処理できないことです。上記の質問の特定のエラーは、著作権記号と考えられるutf8文字に関するものです。

それから私は見つけました。https://stackoverflow.com/q/25814675/350713

そこに記載されているテストスクリプトを使用してください。

filename = 'utf-8·filename.txt'
print(filename)

私のコンピュータでは、次のようにPython 2を使用するとエラーが発生しますが、Python 3ではエラーは発生しません。

python test.py 
  File "test.py", line 1
SyntaxError: Non-ASCII character '\xc2' in file test.py on line 1, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

python3 test.py 
utf-8·filename.txt

しかし、ポスターは両方とも同じ間違いを犯しました。

また、ポスターはascii実行時にPython 2と3の両方をサポートしています。

/usr/bin/python -c 'import sys; print(sys.getdefaultencoding())'

asciiPython 2とPython 3がありますutf8

何が起こっているのかわからないまま、Stack OverflowのPythonルームの専門家に質問しました。 Antti Haapalaは次にいくつかの質問をし、次のような会話が行われました。http://chat.stackoverflow.com/transcript/message/22902726#22902726)

Antti Haapala   : @WaitingforDev... what is your python3 version?

WaitingforDev...: ooooops
                  I run python3 --version
                  and I get
                  Python 2.7.8

したがって、ポスターのPython 3は実際にPython 2であり、これはこれらの動作を説明しています。私はその時尋ねた。

FaheemMitha: what does `ls -la /usr/bin/python3` show?
Waiting for Dev...: @FaheemMitha it pointed to /usr/bin/python
