Virtualenv: Невозможно создать среду Python 2.7

Созданный на 19 мар. 2020  ·  4Комментарии  ·  Источник: pypa/virtualenv

Проблема

В среде докеров Ubuntu 18.04 tox пытается выполнить virtualenv --no-download --python /usr/bin/python2.7 py27 . С virtualenv 20.0.10 это сработало. Начиная с 20.0.11, это не срабатывает с ошибкой:

TypeError: unsupported operand type(s) for /: 'tuple' and 'str'

Он все равно должен работать.

Среда

Предоставьте как минимум:

  • ОС: Ubuntu 18.04
  • pip list хоста python, на котором установлен virtualenv :

Конкретная ошибка выглядит так, как будто она была введена в # 1728 по адресу https://github.com/pypa/virtualenv/blob/master/src/virtualenv/create/via_global_ref/builtin/python2/python2.py#L79 -L85. В частности, эта строка (https://github.com/pypa/virtualenv/blob/master/src/virtualenv/create/via_global_ref/builtin/python2/python2.py#L85)

        return mappings[0] / name, mappings[1], False

вероятно должно быть

        return mappings[0][0] / name, mappings[0][1], False

поскольку сопоставления представляют собой список кортежей.

FWIW, я вижу это с unicode вместо str :
