特拉维斯 CI 错误，而 devtools::chech() 没有

Question

Here is the package in github.

正如您在 travis.yml 中看到的，警告不会被视为错误。当我在控制台中执行check() 时，没有错误。结果如下：

0 errors ✓ | 4 warnings x | 1 note x

这是 Travis CI 的最后几行。

我应该修改什么以使其通过 Travis CI？

Answer 1

我觉得你的包至少依赖于raster 和sf；并且您的脚本不会安装它们：

1: In i.p(...) : installation of package ‘terra’ had non-zero exit status
2: In i.p(...) : installation of package ‘units’ had non-zero exit status
3: In i.p(...) : installation of package ‘raster’ had non-zero exit status
4: In i.p(...) : installation of package ‘sf’ had non-zero exit status

原因很可能是您没有安装所需的系统依赖项（GDAL、GEOS、...）。在安装这些软件包之前，您需要在系统中添加类似的内容

sudo apt-get install libgdal-dev libproj-dev libgeos-dev libudunits2-dev netcdf-bin

我认为在这样的 travis 文件中

addons:
  apt:
    packages:
      - libgdal-dev
      - libproj-dev
      - libudunits2-dev
      - netcdf-bin
