Ошибка при установке библиотеки symfit в pyhton

Question

Я получаю сообщение об ошибке при установке библиотеки symfit.

Я использую pip3 в cmd для установки библиотеки.

вот ошибка в cmd:

I также установлены зависимости

sympy, numpy, scipy

Answer 1

Убедитесь, что вы установили 32-битную python специально, в противном случае установите вместо нее 64-битную версию

Сообщение об ошибке вызвано тем, что symfit на pypi имеет требование scipy<1.2,>=1.0:

Collecting scipy<1.2,>=1.0

Именно поэтому ваша установка удаляет ваш scipy 1.4 и загружает версию 1.1. Поскольку у него нет колес для python 3.8 (слишком старый), он загружает исходный код, а затем завершается ошибкой, поскольку не может найти компилятор C.

No module named 'numpy.distutils._msvccompiler'

Что вам нужно сделать, это установить symfit из репозитория github, поскольку он был обновлен с момента последнего выпуска и теперь имеет требования, совместимые с python 3.8:

 pip install git+https://github.com/tBuLi/symfit
