缺少 home/user/anaconda2 中的写权限

Question

我正在尝试使用命令安装 opencv

conda install opencv

此命令在我的笔记本电脑上工作，但是当我在台式计算机上尝试时出现以下错误。两个系统都运行 Ubuntu 14.04

# You don't appear to have the necessary permissions to install packages

Answer 1

问题是安装了“anaconda”的“anaconda2”文件夹被设置为“仅限访问”，因为“anaconda2”文件夹的所有者是“root”。现在我使用命令更改了“anaconda2”文件夹的所有权

sudo chown -R ws2 anaconda
sudo chown -R usr foldername
