open cv : 一系列 OpenCV 便利函数。imutils 和 cvuitls 未安装

Question

我试过这个链接https://pypi.python.org/pypi/cvutils/0.1

我尝试了很多方法，但我没有找到正确的方法来安装这些东西。我的点子版本是 1.5.4 。 pip install imutils and cvutils登录终端如下：I'm getting this error which is shown by red color for every installation

您必须具有 root 权限才能在系统范围内安装 python 包。

使用sudo pip install cvutils 或将其安装在虚拟环境中。
