exchangelib:在OS系统上寻找winkerberos

Question

我正试图在Mac (OSX10.13.5)上安装exchangelib。我在安装过程中遇到了问题，所以我创建了一个最低限度的工作环境：

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，我发现它试图加载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'
>>>

我有点不知所措。有什么想法，如何使安装不寻找闪烁？

它似乎是试图先加载pykerberos，这会导致库问题(符号未找到：_mempcpy)失败，而作为后盾，它试图加载它找不到的winkerberos。一旦您能够使系统上的pykerberos正常工作，它就会开始工作。
