Мое решение

apt-get --reinstall install python-chardet

Анатомия проблемы

на моей платформе dpkg -L python-chardet утверждала, что python-chardet будет использовать эти файлы:

, но проблема в том, что ни одно из них не было:

# ls /usr/lib/python2.7/dist-packages/chardet
ls: cannot access /usr/lib/python2.7/dist-packages/chardet: No such file or directory

Еще один тест, который вы можете выполнить

, вы также можете проверить чарте, используя двоичный файл:

/usr/bin/chardet

Если он выдает что-то вроде этого, lib нарушается:

# /usr/bin/chardet 
Traceback (most recent call last):
  File "/usr/bin/chardet", line 26, in <module>
    import chardet
ImportError: No module named chardet

Мое первоначальное сообщение об ошибке:

, как я уже сказал, просто переустановить чарт:

apt-get --reinstall install python-chardet
