python - 错误: command 'c++' failed with exit status 1

Question

所以我尝试按照 https://andrewwilkinson.wordpress.com/2012/01/23/integrating-python-and-javascript-with-pyv8/ 的说明安装 Pyv8

    sudo aptitude install scons libboost-python-dev
    svn checkout http://v8.googlecode.com/svn/trunk/ v8
    svn checkout http://pyv8.googlecode.com/svn/trunk/ pyv8
    cd v8
    export PyV8=`pwd`
    cd ../pyv8
    python setup.py build
    sudo python setup.py install

运行有关build设置的倒数第二个命令时出现错误。

Answer 1

这是因为gcc和g++的版本对我来说太低了，因为我在安装cuda时降级了它。只需按照以下命令操作即可:

$ cd /usr/bin 
$  rm gcc
$ ln -s gcc-5 gcc  
$ rm g++
$ ln -s g++-5 g++ 

完成。
