Python ldap macOS-ValueError:选项错误 [英] Python ldap macOS - ValueError: option error

问题描述

我正在尝试在macOS Sierra上设置python-ldap. 当我尝试使用该模块时(该模块在CentOS上运行的实时环境中有效) 我收到以下错误，该错误在搜索时似乎与在macOS上安装OpenLDAP或python-ldap有关，但是我还没有找到一篇文章介绍如何修复它.

I'm trying to setup python-ldap on macOS Sierra. When I try use the module (which works in my live env running on CentOS) I get the below error, which upon searching looks to be something to do with the install of OpenLDAP or python-ldap on macOS, but I'm yet to find an article that explains how to fix it.

到目前为止，我已经通过自制软件安装了OpenLDAP，但无法解决此问题:

Thus far I have installed OpenLDAP via homebrew which has not fixed the issue:

错误:

我已经按照以下说明通过brew安装了openldap

I have installed openldap via brew as per the below

alexs-mbp:~ alex$ brew install openldap
Warning: openldap is a keg-only and another version is linked to opt.
Use `brew install --force` if you want to install this version
alexs-mbp:~ alex$ brew install openldap --force
Warning: openldap-2.4.44 already installed, it's just not linked.

我已经用pip安装了python-ldap

and i have installed python-ldap with pip

alexs-mbp:~ alex$ sudo pip install python-ldap

推荐答案

对我来说，解决方案是在执行pip install python-ldap

The solution for me was that I needed to include the brew-based openldap libraries when doing the pip install python-ldap

您可以通过以下方式找到所需的信息:brew info openldap上面写着类似的内容:

The information you'll need can be found by doing brew info openldap where it says something like:

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/brew/opt/openldap/lib
    CPPFLAGS: -I/usr/local/brew/opt/openldap/include

我的openldap安装位于/usr/local/brew/opt/openldap/，因此需要这样的命令:

My openldap install is at /usr/local/brew/opt/openldap/so this required a command like:

LDFLAGS="-L/usr/local/brew/opt/openldap/lib" CPPFLAGS="-I/usr/local/brew/opt/openldap/include" pip install python-ldap

尝试卸载python-ldap(pip uninstall python-ldap)，然后运行brew info openldap并使用您的特定路径来打开ldap lib，并在上述命令中包含目录

Try uninstalling python-ldap (pip uninstall python-ldap) and then run the brew info openldap and use your specific paths to openldap lib and include directory in the above command

注意:我的clang编译器也找不到MacOS SDK sasl.h，但我不知道这是否就是我.通过在上述命令行中添加--global-option=build_ext --global-option="-I$(xcrun --show-sdk-path)/usr/include/sasl"可以解决此问题

Note: I also had an issue with my clang compiler not finding the MacOS SDK sasl.h, but i dont know if this was just me. This was solved by adding --global-option=build_ext --global-option="-I$(xcrun --show-sdk-path)/usr/include/sasl" to the above command line
