Virtualenv: 20b1 "RuntimeError: не удалось найти интерпретатор для встроенного обнаружения python_spec='venv1/bin/python'"

Я думаю, что это будет https://github.com/pypa/virtualenv/issues/1512 , так вы пытаетесь переписать ветку?

Также, пожалуйста, публикуйте прогоны с -vv, чтобы мы получили больше информации 😊

все еще не работает - вот с rewrite и -vv :

Это похоже на допустимую ошибку, мы, вероятно, еще не обрабатываем относительные пути, посмотрим 👍

также может быть полезно отметить, что venv1/bin/python сама по себе является символической ссылкой:

$ ls -al venv1/bin/python
lrwxrwxrwx 1 asottile asottile 7 Jan 28 16:04 venv1/bin/python -> python3

только что заметил это при просмотре

Исправлено в #1523

все еще не работает для меня, но теперь так же, как в # 1515, поэтому я продолжу обсуждение здесь:
