考虑以下setup.py文件（例如，此处生成唯一的其他源文件（false.c））：
#!/usr/bin/env python
from setuptools import setup
from distutils.ccompiler import new_compiler
from subprocess import check_call
with open('false.c', 'w') as F:
F.write('int main(int argc, char **argv){ return 1; }\n')
compiler = new_compiler().compiler
check_call(compiler + ['-O3', 'false.c', '-o', 'false'])
setup(
name='false',
scripts=['false'],
)
。当使用python-2 *（在使用此pip install -e .文件的目录中使用setup.py时）将已编译的false可执行文件安装到$VIRTUAL_ENV/bin时，此文件可正常工作。但是，如果我使用python-3 *的虚拟环境，则会因以下错误而失败：（full error log）
