问题描述

我想使用 python-saml 与烧瓶网络应用程序进行 sso 集成。当我尝试使用安装 python-saml 包pip install python-saml时,我收到以下错误消息。

我试过了conda install python-saml,同样的错误,他们在 2 年前停止了这个包。即使我尝试过python3-saml

核心问题在 xmlsec 包中。

是否有任何 conda 频道或 PYPI 提供此软件包?

解决方案


更新

从 1.3.7 版本开始,xmlsecPyPI 上发布了用于 Windows 的预构建轮子,因此您不应再遇到此问题。

原始答案

我已经重建xmlsec了 windows 轮子并将它们上传到我的 fork 的发布页面。要安装,首先安装xmlsec传递额外的 PyPI 索引:

$ pip install xmlsec --extra-index-url=https://hoefling.io/pypi

添加的索引只是将安装请求代理到 Github 版本。

现在安装python3-saml

$ pip install python3-saml

(替代)手动选择 dist

您可以从发布页面手动找到与您的 Python 安装相匹配的轮子,并使用直接链接进行安装,例如

$ python -c "from pip._internal.pep425tags import get_supported; print(*get_supported()[0], sep='-')"
cp37-cp37m-win_amd64
# the matching wheel is thus xmlsec-1.3.6.post1-cp37-cp37m-win_amd64.whl
$ pip install https://github.com/hoefling/xmlsec/releases/download/1.3.6.post1/xmlsec-1.3.6.post1-cp37-cp37m-win_amd64.whl

(可选)xmlsec通过调用测试验证作品

我已经对所有内置车轮执行了测试(查看Appveyor 上的此作业日志),但您也可以在本地运行测试以验证xmlsec安装是否正常:

$ git clone https://github.com/mehcode/python-xmlsec.git && cd python-xmlsec
$ pip install pytest
$ pytest tests/
