问题描述
I am using Python 3 on CentOS 7. I am trying to build a C extension as described here. I have written a simple program, demo.c, which is in a directory in PYTHONPATH. demo.c has the following form.
#include <stdio.h>
#include <stdlib.h>
int main()
{
printf("Hello from demo.c\n");
return 0;
}
此代码运行无误.
from distutils.core import setup, Extension
module1 = Extension('demo',
sources = ['demo.c'])
但是,以下代码
setup (name = 'PackageName',
version = '1.0',
description = 'This is a demo package',
ext_modules = [module1])
产生以下错误.
An exception has occurred, use %tb to see the full traceback.
SystemExit: usage: CInterface.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: CInterface.py --help [cmd1 cmd2 ...]
or: CInterface.py --help-commands
or: CInterface.py cmd --help
error: no commands supplied
推荐答案
该错误表示您需要传递Distutils命令,例如 build
The error is saying you'll need to pass in a Distutils command, such as build
(or probably build_ext
in your case).
python CInterface.py build_ext
