另一方面,当我尝试安装lxml
或requests
一切正常。 关于我搞砸的地方有什么想法吗?
库murmurhash3
适用于 Python > 3.2,起初您试图为 Python 2 编译它。它不起作用,因为该库具有 C 扩展并且 Python 2 和 3 不是相互的 API 兼容。
当然,它会更容易注意到, murmurhash3
会在它的setup.py
检查你的 Python 版本。
既然您正在尝试将其安装到 Python 3,很明显您的编译器有问题! C 标准要求UCHAR_MAX
由现有的每个 C 编译器在<limits.h>
定义,并且在任何当前的个人计算架构上, UCHAR_MAX
应定义为 255,包括 Mac。 Python.h检查这一点。 您的 C 编译器既没有定义UCHAR_MAX
也没有在limits.h
UCHAR_MAX
其设置为255
,但它仍然成功地包含了一些limits.h
。 你的 C 编译器是完全 b0rken
