在conda/M上安装带pip的mmh3包

Question

所以我尝试在MacOS上安装一个需要mmh3的包。在

当我到了那里-我得到的错误，无论出于何种意图和目的，对我来说都可能是不同的语言。在

到目前为止的搜索结果让我相信这与我电脑上的苹果xCode版本有关，但我找到的答案完全没有意义。如果我所做的只是调用pip install mmh3，我不知道如何编辑安装文件。在

输出如下，我知道它很长-但我不知道什么是相关的和不相关的，所以它都在那里。这跟苹果公司改名c++或者类似的东西有关。任何帮助都将不胜感激。请记住，我不知道为什么需要这个包裹，只是它是。在

Answer 1

所以，和往常一样，在你看过之后，答案非常简单。在

解决此问题的方法以及依赖于Python引用的C++库的其他解决方案是在实现包时使用的^ {CD1>}文件中的IF／EXE块。如果在OSX>；=10.7上运行，包含和执行的以下代码行将解决pip和Python的此类投诉。在

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

作为参考，here是关于问题来源的一些信息。在

解决方案的功劳应该归于@honnibal，完整的if/else逻辑和块现在可以通过this link获得，所以您可以有一个squiz来查看发生了什么。在
