面对同样的问题。如果你看一下错误堆栈，它说:

Error: Command failed: /usr/bin/python3.6 -c import sys; print "%s.%s.%s" % sys.version_info[:3];
   File "<string>", line 1
     import sys; print "%s.%s.%s" % sys.version_info[:3];
                                ^
 SyntaxError: invalid syntax

它试图使用Python2，但却使用了不受支持的Python3。

我的系统在使用python命令调用时运行Python3，所以我通过安装Python2并将其别名化为python命令来解决这个问题:
