在安装r-base-core时绕过过度的依赖项

Question

我正试图在一个ubuntu10.10服务器上安装R(通过r基核)。

它正在尝试安装以下所有程序：

我的基础设施空间有限，我不想浪费太多的时间来安装无法在服务器上使用的程序/库(libgnome？火狐？)

1. 为什么我们有所有这些依赖关系呢？是否有一种方法可以轻松地查看整个依赖树或每个依赖树背后的动机？
2. 我真的不关心窗口依赖(因为它们不能被使用)。有什么好的方法来强迫apt/dpkg忽略它们--或者仅仅从源代码编译是明智的吗？

Answer 1

(2)尝试

sudo apt-get --no-install-recommends install r-base-core

Ubuntu默认情况下不仅安装依赖程序，而且还安装推荐的包。

(1)如果您对包解析树感兴趣，请执行以下操作

apt-get --dry-run -o Debug::pkgDepCache::AutoInstall=yes install r-base-core

样本输出

$ apt-get --dry-run -o Debug::pkgDepCache::AutoInstall=yes install r-base-core
NOTE: This is only a simulation!
      apt-get needs root privileges for real execution.
      Keep also in mind that locking is deactivated,
      so don't depend on the relevance to the real current situation!
