python - 在 Windows 中安装 Python-saml 包时出错

Question

我想使用 python-saml 与 Flask Web 应用程序进行 sso 集成。当我尝试使用 pip install python-saml 安装 python-saml 包时，我收到以下错误消息。

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 channel 或 PYPI 提供此软件包？

Answer 1

更新
从 1.3.7 版开始，预制轮子 xmlsec Windows 版已在 PyPI 上发布，因此您不应再遇到此问题。
原答案
我已经重建xmlsec windows 轮子并将它们上传到 releases page of my fork .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 releases page 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)验证 xmlsec通过调用测试工作
我已经对所有构建的轮子执行了测试(查看 this job log on Appveyor )，但您也可以在本地运行测试以验证 xmlsec安装工作:

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