Python 错误：命令'；c++'；失败，退出状态为1

因此，我尝试按照来自的说明安装Pyv8

运行有关生成安装程序的最后二个命令时出错

我按照此链接中的说明进行操作-

并安装了libboost_线程包，解决了这个问题。谢谢

这是因为gcc和g++的版本对我来说太低了，因为我在安装cuda时会将其降级。只需执行以下命令：

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

---

完成了

您得到链接器错误，因为链接器找不到两个Boost库。您需要安装Boost库软件包。

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