我正在尝试在 Mac 上安装 xgboost for Python 3.4，但之后出现以下错误pip3 setup.py install:
File "<string>", line 20, in <module>
File "/private/var/folders/_x/rkkz7tjj42g9n8lqq5r0ry000000gn/T/pip-build-2dc6bwf7/xgboost/setup.py", line 28, in <module>
execfile(libpath_py, libpath, libpath)
NameError: name 'execfile' is not defined
当使用 -v 选项运行它以获得详细输出时，错误如下所示：
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/_x/rkkz7tjj42g9n8lqq5r0ry000000gn/T/pip-build-2dc6bwf7/xgboost

我该如何解决这个问题？
