R 包未检测到 GDAL 的更新版本

R package doesn't detect updated version of GDAL

我正在尝试从 raster 转移到新的 terra R 包,这需要在我的机器上安装最新版本的 GDAL (MacOS 10.14.6)。

我按照此处的说明更新了 GDAL:http://www.alexchubaty.com/post/2020-01-08-using-latest-gdal-macos-redux/,它似乎有效。当我在终端显示 运行 gdalinfo --version 时:

GDAL 3.1.1, released 2020/06/22

但是当我在 R 中加载 terra 库时,它似乎仍然 link 到旧版本的 GDAL (2.4.2):

> library(terra)
This is terra version 0.7.11 (alpha-release)

NOTE: You are using GDAL version 2.4.2 
For full functionality you need at least version 3.0.4

有趣的是,rgdal 包似乎检测到更新版本:

> library(rgdal)

有谁知道如何获取 terra 到 link 最新版本的 GDAL?我猜旧版本仍然安装在机器上的某个地方。

我猜您是从源代码安装的 rgdal,但是 terra 二进制版本 来自 CRAN。因此,在从命令行执行(您已经执行的操作)之后:

brew install pkg-config
brew install gdal

您应该使用以下 R 命令得到您想要的东西

install.packages("terra", type = "source")

或者,对于切削刃

remotes::install_github("rspatial/terra")

祝你 terra 好运!
