У меня на сервере две версии Python, а именно 2.4 и 2.7. Он работает под управлением RHEL 5.8.
На моем сервере уже установлены pip и easy_install.
Когда я пытаюсь установить ipython с помощью easy_install или pip, возникает ошибка, которая, вероятно, не поддерживается в python 2.4.
Я хочу использовать python 2.7 как для pip, так и для easy_install, так как я хотел бы использовать последнюю версию обоих.
Что мне делать, чтобы pip и easy_install использовали python 2.7. Python 2.4 установлен системой по умолчанию, и я хочу сохранить его.
Python 2.7 установлен в другом месте.
Ниже приведена трассировка как для easy_install, так и для pip. Оба заканчиваются одной и той же ошибкой. Любая помощь приветствуется.
