python - exchangelib：在 OS X 系统上寻找 winkerberos

问题描述

我正在尝试在 Mac (OS X 10.13.5) 上安装 exchangelib。我在安装时遇到问题，所以我创建了一个最小的工作环境：

pushd /tmp
curl -SLO https://repo.continuum.io/miniconda/Miniconda3-latest-MacOSX-x86_64.sh
bash ./Miniconda3-latest-MacOSX-x86_64.sh -b -p /tmp/lxml
source /tmp/lxml/bin/activate
conda create -n py35 python=3.5 lxml -y
source activate py35

然后我在那个环境中安装了 exchangelib。但是，当我尝试使用它时，我发现它正在尝试加载 winkerberos 而不是 pykerberos。

>>> import exchangelib
Traceback (most recent call last):
  File "/tmp/lxml/envs/py35/lib/python3.5/site-packages/requests_kerberos/kerberos_.py", line 2, in <module>
    import kerberos

    import winkerberos as kerberos
ImportError: No module named 'winkerberos'
>>>

我在这里有点不知所措。任何想法如何让安装不寻找winkerberos？

解决方案

看起来它正在尝试首先加载 pykerberos，但由于库问题（未找到符号：_mempcpy）而失败，并且作为后备尝试加载未找到的 winkerberos。一旦您可以使系统上的 pykerberos 工作，这应该开始工作。
