我试图安装Python包dulwich:
pip install dulwich
Run Code Online (Sandbox Code Playgroud)
但我得到一个神秘的错误信息:
error: Unable to find vcvarsall.bat
Run Code Online (Sandbox Code Playgroud)
如果我尝试手动安装包,也会发生同样的情况:
> python setup.py install
running build_ext
building 'dulwich._objects' extension
error: Unable to find vcvarsall.bat
Run Code Online (Sandbox Code Playgroud) 我想用Cython包装一个包含C++和OpenMP代码的测试项目,并通过setup.py文件使用distutils构建它.我的文件内容如下所示:
from distutils.core import setup
from distutils.extension import Extension
from Cython.Build import cythonize
from Cython.Distutils import build_ext
modules = [Extension("Interface",
["Interface.pyx", "Parallel.cpp"],
language = "c++",
extra_compile_args=["-fopenmp"],
extra_link_args=["-fopenmp"])]
for e in modules:
e.cython_directives = {"embedsignature" : True}
setup(name="Interface",
cmdclass={"build_ext": build_ext},
ext_modules=modules)

该-fopenmp标志与gcc一起用于编译和链接OpenMP.但是,如果我只是调用
cls ~/workspace/CythonOpenMP/src $ python3 setup.py build
Run Code Online (Sandbox Code Playgroud)
这个标志无法识别,因为编译器是clang:
running build
running build_ext
