【问题描述】:

我创建了一个云数据处理集群,并在我的初始化脚本中尝试安装 libopencv-dev,但我不断收到未满足的依赖项错误:

sudo apt-get install libopencv-dev

我不知道出了什么问题,我尝试使用 debian 8 创建一个计算引擎并在其上运行相同的命令,它可以正常工作,但在为 dataproc 集群创建的机器上无法正常工作,有谁知道是什么问题?

    【解决方案1】:

    似乎他们使用 backports,所以要安装 libopencv-dev,我必须使用以下命令从 backports repo 安装它:

    sudo apt-get -t jessie-backports install libopencv-dev

      【解决方案2】:

      尝试使用 aptitude 安装

      运行以下命令

      sudo apt install aptitude -y sudo aptitude install libopencv-dev
