[英]Trying to install anything with pip on macos and cannot
I think I have a problem with my mac os system.我想我的 mac os 系统有问题。 Everything I try to install on it using pip I get the same errors over and over again, I have pasted just the lines that display an error to not overcrowd this thread:我尝试使用 pip 在其上安装的所有内容我一遍又一遍地得到相同的错误,我只粘贴了显示错误的行,以免使该线程过度拥挤:

On the other hand when I try to install lxml
or requests
everything works great.另一方面,当我尝试安装lxml
或requests
一切正常。 Any thoughts on where I have messed up?关于我搞砸的地方有什么想法吗?
The library murmurhash3
is meant for Python >3.2 and at first you were attempting to compile it for Python 2. It doesn't work as the library has a C extension and Python 2 and 3 are not mutually API compatible.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。
Of course it would have been easier to notice, would murmurhash3
have checked your Python version in its setup.py
.当然,它会更容易注意到, murmurhash3
会在它的setup.py
检查你的 Python 版本。
Now that you're trying to install it to Python 3, it is clear that there is something very wrong with your compiler!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! The C standard requires that UCHAR_MAX
is defined in <limits.h>
by every single C compiler in existence and on any current personal computing architecture the UCHAR_MAX
should be defined to 255, Macs included. 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 checks this. Python.h检查这一点。 Your C compiler defined neither UCHAR_MAX
nor did it set it to 255
in limits.h
but it still successfully included some limits.h
.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
。 Your C compiler is utterly b0rken你的 C 编译器是完全 b0rken
