无法在 Ubuntu Xenial 上安装 libopencv-dev

还有人见过这个问题吗？我正在尝试在 Ubuntu Xenial LTS 中安装 OpenCV。

我尝试取消注释 /etc/apt/sources.list 中的 deb-src 条目，但仍然不起作用。

sudo apt-get -f 安装 libopencv-dev

答案1

请尝试以下操作：sudo aptitude install libopencv-dev

当您收到询问解决依赖关系的问题时，您将看到 (Y/n/q)?。输入 n。

看看下一个 (Y/n/q) 问题是什么。通常这部分会降级其中一个依赖项，以便解决其他依赖项。这对我来说很有效！希望对你也一样。

答案2

使用 aptitude 而不是 apt-get。它更智能。它不仅可以帮您处理冲突软件包的降级，还会提出一系列建议，询问您希望使用众多可能的建议工作方案中的哪一种。

sudo aptitude install myNewPackage

如果你的机器上还没有 aptitude，可以使用

sudo apt-get install aptitude
