在windows中安装Pythonsaml包时出错

Question

我想使用python saml与flask web app进行sso集成。当我试图使用pip install python-saml安装python saml包时，我收到以下错误消息

我试过使用conda install python-saml，同样的错误也发生在两年前，他们停止了这个包。甚至我也试过python3-saml

核心问题在xmlsec包中

是否有康达频道或PYPI提供此软件包

Answer 1

更新

从1.3.7版开始，针对Windows的xmlsec的预构建控制盘就发布在PyPI上，因此您不应该再遇到这个问题

原始答案

我重建了xmlsec个windows控制盘，并将它们上载到releases page of my fork。要安装，首先安装xmlsec，并传递附加的PyPI索引：

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

添加的索引只是代理Github版本的安装请求

现在安装python3-saml：

$ pip install python3-saml

（可选）手动选择dist

您可以从releases page中手动找到与Python安装相匹配的控制盘，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）通过调用tests

我已经对所有构建的控制盘执行了测试（请检查this job log on Appveyor），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/

Answer 2

从未在这里使用过python saml。。。但是，在搜索此错误时，我发现了以下GitHub问题：Issue 1和Issue 2

他们都谈到dm.xmlsec.binding的一个问题

最佳，
