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

核心问题是在 xmlsec 包中..

是否有任何 conda 频道或 PYPI 提供此软件包?

更新

从版本 1.3.7 开始,xmlsecWindows 的预构建轮子已发布在 PyPI 上,因此您不应再遇到此问题。

原答案

我已经重建了xmlsecWindows 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传递附加的 PyPI 索引:

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

添加的索引仅代理对 Github 版本的安装请求。

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安装匹配的轮子并使用直接链接安装它,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通过调用测试来验证是否有效

我已经对所有构建的轮子执行了测试(在 Appveyor 上查看此作业日志),但您也可以在本地运行测试以验证xmlsec安装是否正常工作:

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