Mac使用sudo运行python会使它得到错误的库

我正试图在我的mac电脑上安装pycuda。 问题是，当我使用sudo运行python时，python 6的版本是错误的，这是pycuda所要求的。 我怎样才能解决这个问题

以普通用户身份键入

哪个python

，然后查看您正在运行哪个python。更改root的PATH环境变量，使root运行与您相同的路径。它与python相同，您需要将

/usr/local/lib/python2.7/site packages

放在root路径的第一位

导入sys；sys.path

output for tware？for

sudopython

syspath返回一个较小的字符串
