Похоже, что установка завершена отлично. Но после этого, если я сделаю следующее, он все равно вернет старую версию. Что мне не хватает?

pi@raspberrypi:~ $ python3 -c "import cython;print(cython.__version__)" 
0.21.1 

Answer 1

Из журнала я могу читать Installing cython script to /usr/local/bin. Я экстраполирую, что библиотека установила в /usr/local/python3something. Две альтернативы:

1. повторно установить с помощью pip3 install --user --upgrade cython==0.24.1 и убедитесь, что ~/.local/bin в вашем PATH environment variable.
2. добавьте /usr/local/bin к вашим PATH environment variable и /usr/local/python3something/site-packages к переменной LD_LIBRARY_PATH.

Действительно, часть python3something должна быть изменена, чтобы отражать точный путь в вашей системе. Вариант «1» выше должен работать, даже если моя экстраполяция неверна.
