Я пытаюсь установить пакет python, который не является общедоступным. Однако проблема здесь не в пакете, а в том, что инструменты ms build не находят libssl.lib . Вот ошибка, которую я получаю, когда он пытается установить криптографию. Пожалуйста, обратите внимание, что у меня была установлена криптография с использованием pip отдельно, но пакет все еще пытается ее собрать и установить.

Я также включил OpenSSL в переменные среды

Тем не менее, я продолжаю получать указанную выше ошибку. Я также переустановил Visual Studio build tools 2019. Не совсем уверен, что еще я могу попытаться исправить эту ошибку.

Похоже libpath , что используемые MS build tools не имеют OpenSSL пути к библиотеке, поэтому он не может найти libssl.lib . Одним из возможных решений было бы скопировать .lib файлы из openssl каталога, который вы указали в переменных среды, в библиотеку Python c:usersadminappdatalocalprogramspythonpython38-32libs . Это должно сработать.
