xmlsec安装报错

xmlsec安装报错

主机环境：macos M2

✗ uname -a
Darwin pgy.local 22.3.0 Darwin Kernel Version 22.3.0: Mon Jan 30 20:38:43 PST 2023; root:xnu-8792.81.3~2/RELEASE_ARM64_T8112 arm64

python版本：

 ✗ pyenv --version && python -V
pyenv 2.3.17
Python 3.9.1

安装依赖

官方安装文档为：xmlsec 1.3.13，安装步骤为

xcode-select --install
brew install libxml2 libxmlsec1 pkg-config

安装完成后查看libxml、libxmlsec1的版本号如下：

brew info libxml2 libxmlsec1
==> libxml2: stable 2.10.4 (bottled), HEAD [keg-only]
==> libxmlsec1: stable 1.3.0 (bottled)

官方要求版本为：

libxml2 >= 2.9.1
libxmlsec1 >= 1.2.1

安装报错

依赖环境已经安装完成，但是安装xmlsec会有如下报错：

 ✗ pip install xmlsec

报错分析与解决

从报错信息可以看出： brew已经成功安装了libxmlsec1，但xmlsec依旧报错，报错原因是brew安装的libxmlsec1的库有问题，导致存在一些语法的错误；

从官方的一个issues当中可以看到，libxml的包确实在M2上面有一些问题，按照issues当中的方式，替换libxmlsec1.rb文件即可

https://github.com/xmlsec/python-xmlsec/issues/254

对比一下两个文件的差异，只是将新版本1.3.0替换为了1.2.37
