我不知道如何解决这个问题。我也尝试安装其他xmlsec软件包，但没有任何效果

Answer 1

这表示PEP 517不支持您尝试安装的控制盘。 请尝试升级以下软件包，然后再次尝试安装

pip install --upgrade pip setuptools wheel

Answer 2

我在安装xmlsec时遇到了类似的问题。它为我做的是重新安装此处列出的所需本机库：https://pypi.org/project/xmlsec/

安装起来很简单：brew install libxml2 libxmlsec1 pkg-config

Answer 3

此处列出的Xmlsec https://pypi.org/project/xmlsec/指向需要安装的本机库

sudo apt-get install pkg-config libxml2-dev libxmlsec1-dev libxmlsec1-openssl
