问题描述

使用Cython界面为时间试用运行迭代循环以实现几何级数.

Running an iterative loop for a geometric progression for a time trial, using the Cython interface.

获取编译错误(shift-enter):CompileError:命令'gcc'失败，退出状态为1

Get an error on compile (shift-enter): CompileError: command 'gcc' failed with exit status 1

%load_ext Cython

推荐答案

我知道这个问题已经很久了，但我认为这可能会对其他人有所帮助.

I know this question is quite old but I thought this may help some others.

我在Windows上遇到了一个旧的Py2.7项目的问题.

I ran into this issue on Windows for an old Py2.7 project.

如果在Windows上并使用Py2.7，请检查是否已安装用于Python的MS Visual Studio C ++编译器(

If on Windows, and using Py2.7 check that you have the MS Visual Studio C++ compiler for Python installed (download link). Not sure what changes are necessary for Py3.

对于您的anaconda环境，请找到Lib\distutils目录并创建一个distutils.cfg文件(如果尚未存在，请根据需要修改当前文件).

For your anaconda environment, locate the Lib\distutils directory and create a distutils.cfg file (if not already there, otherwise just modify the current file as necessary).

您希望构建配置如下所示.

You want the build config to look like below.

[build]
compiler=msvc

[build]
compiler=msvc

如果在Linux上，请确保您有必要的devel软件包可用，例如

If on linux, make sure you have the necessary devel packages available, e.g.

Ubuntu:apt-get install python-devel
