У меня есть ПК с Windows 7 с установленным Visual Studio 2015 upgrade 3, и я хотел бы установить библиотеку backports.lzma для Python с помощью pip.
Я скачал и извлек XZ Utils в папке Program Files. (XZ Utils является обязательным для установки библиотеки бэкпортов, как указано на сайте Pypi )
Это вывод пипса:
