在 conda/MacOS 上使用 pip 安装 mmh3 包

Question

所以我试图在 MacOS 上再次设置和安装一个需要 mmh3 的包。

当我到达那里时——我收到了错误，出于所有意图和目的，这些错误对我来说也可能是另一种语言。

到目前为止的搜索让我相信这与我机器上的 Apple 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。

输出如下，我知道它很长 - 但我不知道什么是相关的，什么是不相关的，所以它就在那里。 这与 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这个包，就是这样。

Answer 1

我遵循了链接https://anaconda.org/conda-forge/mmh3中的指南，发现它有效。

要使用 conda 安装此软件包，请运行以下命令之一：

conda 安装-c conda-forge mmh3

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

Answer 2

因此，一如既往，答案在您看过之后非常简单。

这个问题以及任何其他依赖于从 Python 引用的 C++ 库的解决方案是用于实现包的setup.py文件中的 if/else 块。 如果在 OSX >= 10.7 上运行，则包含并执行以下代码行将解决来自 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， 这里有一些关于问题来源的信息。

解决方案的功劳应归功于@honnibal，现在可通过此链接获得完整的 if/else 逻辑和块，因此您可以进行测验以了解发生了什么。
