Question

所以我试图在MacOS上再次设置并安装需要mmh3的软件包。

当我到达那里时-我收到错误消息，出于所有意图和目的，这些错误也可能对我来说是另一种语言。

到目前为止，

搜索使我相信与我在计算机上拥有的Apple xCode版本有关某事，但是我发现的答案完全没有意义。如果我只想打电话给pip install mmh3，我不知道如何编辑安装文件。

输出如下，我知道它很长-但是我不知道什么是无关紧要的，所以就在那里。与APple重命名c ++或类似的东西有关。任何帮助都感激不尽。请记住，我不知道为什么需要此软件包，只是这样。

Answer 1

我遵循了https://anaconda.org/conda-forge/mmh3链接中的指南，发现它可行。

要使用conda安装此软件包，请执行以下操作之一：

conda install -c conda-forge mmh3

conda install -c conda-forge / label / cf202003 mmh3

Answer 2

因此，一如既往，答案在您看到后非常简单。

此问题以及所有其他依赖Python引用的C ++库的解决方案都是在实现该软件包时使用的setup.py文件中的if / else块。如果在OSX> = 10.7上运行，则包含并执行的以下代码行将解决pip和Python的此类投诉。

COMPILE_OPTIONS["other"].append("-stdlib=libc++")
LINK_OPTIONS["other"].append("-lc++")
LINK_OPTIONS["other"].append("-nodefaultlibs")

作为参考，here是有关问题来源的一些信息。

该解决方案的信用应该转到@honnibal，现在可以通过this link获得完整的if / else逻辑和块，因此您可以竞猜一下发生了什么。
