已经尝试了这里概述的方法:如何在Mac OS X上安装加密?
安装OpenSSL，只是给我同样的错误。
感谢您的帮助
谢谢!
需要setuptools版本58.0或更高版本才能构建。看到输出:
pkg_resources.VersionConflict: (setuptools 49.2.1 (/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/site-packages), Requirement.parse('setuptools>=58.0'))
尝试pip install --upgrade pip setuptools然后重试安装。
