Мне нужно использовать версию Python, отличную от установленной в системе. Чтобы сделать это, я использовал penv для установки нужной версии - 2.7.12, а затем отображается правильная версия:
pyenv which python
/root/.pyenv/versions/2.7.12/bin/python
Когда я пытаюсь создать новую виртуальную среду, используя следующую команду:
[root@localhost site-packages] pyenv virtualenv 2.7.12 nanovar
New python executable in /root/.pyenv/versions/2.7.12/envs/nanovar/bin/python2.7
Also creating executable in /root/.pyenv/versions/2.7.12/envs/nanovar/bin/python

Complete output from command /root/.pyenv/version...anovar/bin/python2.7 - setuptools pip wheel:
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

Я не могу понять проблему кодека ascii, я попытался установить LC_CTYPE = "C.UTF-8", но безрезультатно. Что может быть не так? Является ли система установленным Python мешающим Python, который я установил с pyenv?
