我正在使用Ubuntu 14.04 LTSAnaconda python安装：

Python 3.5.1 :: Anaconda 2.4.1（64位）

我正在尝试使用此食谱在我的ipython笔记本中启用C ++交互式编译：

import IPython.core.magic as ipym

@ipym.magics_class
class CppMagics(ipym.Magics):
    @ipym.cell_magic
    def cpp(self, line, cell=None):
        """Compile, execute C++ code, and return the standard output."""
        # Define the source and executable filenames.
        source_filename = 'temp.cpp'
        program_filename = 'temp.exe'
        # Write the code contained in the cell to the C++ file.
        with open(source_filename, 'w') as f:
            f.write(cell)
        # Compile the C++ code into an executable.
        compile = self.shell.getoutput("g++ {0:s} -o {1:s}".format(
            source_filename, program_filename))
        # Execute the executable and return the output.
        output = self.shell.getoutput(program_filename)
        return output

def load_ipython_extension(ipython):
    ipython.register_magics(CppMagics)

当我使用以下命令执行单元格时，是否用ipython notebok或jupyter notebook（我相信第一个别名还是第二个别名）启动笔记本？

%load_ext cppmagic

我收到以下错误：

食谱中的代码似乎与我将其放在以下目录中的官方文档（两者都使用IPython.core.magic.magics_class）一致cppmagic.py

〜/ .ipython / profile_default /启动

使其在笔记本启动时自动加载，但我无法感受到魔力。有人可以帮忙吗？
