我认为我的mac os系统有问题.我尝试使用pip安装在它上面的所有东西,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,以确保该线程不会过度拥挤:
I think I have a problem with my mac os system. 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:

另一方面,当我尝试安装lxml
或requests
时,一切正常.对我搞砸的地方有什么想法吗?
On the other hand when I try to install lxml
or requests
everything works great. Any thoughts on where I have messed up?
推荐答案
库 murmurhash3
>是针对Python> 3.2的,最初您尝试针对Python 2进行编译.由于该库具有C扩展名,并且Python 2和3与API不兼容,因此该代码不起作用.
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.
当然会更容易注意到,如果murmurhash3
在setup.py
中检查了您的Python版本.
Of course it would have been easier to notice, would murmurhash3
have checked your Python version in its setup.py
.
现在您要尝试将其安装到Python 3,很明显,编译器出了点问题! C标准要求,UCHAR_MAX
是由存在的每个单个C编译器在<limits.h>
中定义的,在任何当前的个人计算体系结构上,UCHAR_MAX
都应定义为255,包括Mac. Python.h 进行检查.您的C编译器既未定义UCHAR_MAX
,也未在limits.h
中将其设置为255
,但仍成功包含 some limits.h
.您的C编译器完全崩溃了
Now that you're trying to install it to Python 3, it is clear that there is something very wrong with your compiler! 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. Python.h checks this. 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
. Your C compiler is utterly b0rken
