协助在 Mac 上安装“rgdal”软件包

Question

如何在 MacOS Catalina 上安装“rgdal”软件包？

运行以下代码：

 install.packages('rgdal', type = "source", configure.args=c(
  '--with-gdal-config=/Library/Frameworks/GDAL.framework/Programs/gdal-config',
  '--with-proj-include=/Library/Frameworks/PROJ.framework/Headers',
  '--with-proj-lib=/Library/Frameworks/PROJ.framework/unix/lib'))

获取以下错误消息：

Answer 1

按照 Ish 的评论安装并使用 Homebrew。它将使此安装工作正常，并且您将能够避免 MacOSX 上 R 包的其他常见安装错误。

在 Homebrew 安装后在终端中运行 'brew install gdal'，然后在 R 中使用安装包 'install.packages("rgdal", type="source")'

尝试先安装 rgeos，然后安装 rgdal，它对我有用

install.packages("rgeos", repos="http://R-Forge.R-project.org", type="source")
install.packages("rgdal", repos="http://R-Forge.R-project.org", type="source")
