Question

中提到的解决方案

这是终端输出（OS是Ubuntu 14.04 64位）

~$ conda install -c r r=3.4.1

Fetching package metadata .............
Solving package specifications: .

UnsatisfiableError: The following specifications were found to be in conflict:
  - opencv
  - r 3.4.1* -> r-base 3.4.1 -> ncurses 5.9*
Use "conda info <package>" to see the dependencies for each package.

我遵循终端建议：

所有网址opencv均来自https://repo.continuum.io/pkgs/free/linux-64。假设这些是Anaconda中所有opencv版本的URL而不是我的机器，我是否正确？

然后我尝试

~$ conda info R

它提供了Anaconda提供的大量R版本表。值得注意的是这个输出：

    r-recommended 3.4.1

显然，在Anaconda R频道中可以使用R 3.4.1。然而安装失败了。我该如何修复或更好地排除故障？

Answer 1

您必须遵循依赖关系链，直到找到实际冲突。在这种情况下，错误是因为Python（在这种情况下为2.7）需要public holder onCreateViewHolder(ViewGroup parent, int viewType) { return new holder(new CourseRaceButton(context)); }，而R需要ncurses 6.0.*。您应该创建一个新环境来安装R：

ncurses 5.9.*

Conda安装3.4.1冲突规范：opencv和r-base或ncurses5.9 *
