home/user/anaconda2 中缺少写入权限

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有效，但当我在台式电脑上尝试时出现以下错误。两个系统都运行 Ubuntu 14.04

答案1

问题是，安装“anaconda”的“anaconda2”文件夹被设置为“仅访问”，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

答案2

请尝试使用 运行您的命令sudo，如下所示：

  sudo conda install opencv

答案3

按照以下命令，并在出现与这些权限相关的问题时进行相应的处理。我在这里所做的是更改了 anaconda 目录中“pkgs”文件夹的所有文件和子文件夹的权限。 sudo chown -R'用户'：/home/user/anaconda/pkgs

就你的情况来说这对我有用

sudo chown -R ws2: /home/ws2/anaconda2
