Как исправить, казалось бы, бесконечный цикл при создании виртуальной среды с Python 3?

Question

В приглашении Cmd указано, что выполняется virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe несколько раз и никогда не создается виртуальная среда.

Я пытался обновить pip и python и выполнил варианты команды virtualenv mypython

virtualenv mypython

Я ожидаю, что будет создана папка с именем, следующим за командой virtualenv.

Но фактический результат таков:

Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe

Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe

Пока я не нажму ctrl-c который дает это:

Answer 1

Вероятно, вы используете версию 16.6.1 модуля virtualenv, которая вызывает эту ошибку, попробуйте использовать следующий код для установки 16.6.0:

 pip install virtualenv==16.6.0

Затем попробуйте снова создать виртуальную среду.

Answer 2

Из-за обновления virtualenv до версии 16.0.2.Попробуйте: pip install virtualenv --upgrade
