xmlsec 未安装在 Mac 上

Question

我正在尝试使用 pysaml2 将 AWS 的 SSO 集成到我的 Flask 应用程序中，pysaml2 需要 xmlsec，但我在安装时遇到问题。

这是我收到的错误：

pip install xmlsec

  note: This error originates from a subprocess, and is likely not a problem with pip.

我已经安装了 homebrew 并安装了 libxml2、libxmlsec1 和 pkg-config。然而问题仍然存在。有谁知道解决办法吗

我也尝试过其他堆栈溢出问题的解决方案，但它们与我的情况并不完全匹配，并且不起作用。

Answer 1

1. 检查

   pkg-config

   访问：确保

   pkg-config

   在您的路径中。

 which pkg-config

如果没有任何返回，则它不在您的路径中。

2. 设置

   PKG_CONFIG_PATH

   ： 安装前先设置路径：

 export PKG_CONFIG_PATH="/usr/local/opt/libxml2/lib/pkgconfig:/usr/local/opt/libxmlsec1/lib/pkgconfig"
 pip install xmlsec

3. 带日志记录的直接安装： 直接从源安装获取详细错误：

git clone https://github.com/mehcode/python-xmlsec.git
cd python-xmlsec
pip install -v .

4. 使用虚拟环境： 创建一个隔离的 Python 环境并安装在：

python -m venv myenv
source myenv/bin/activate
pip install xmlsec

5. 安装编译工具：

xcode-select --install
