Windows 11下安装R语言terra包遇Zip文件下载超时问题求助

执行安装命令install.packages("terra")后返回如下错误：

> install.packages("terra")

In addition: Warning messages:

预期能成功安装terra包，但因下载超时导致失败。

解决办法 #

• 延长下载超时时间：执行install.packages("terra", timeout = 300)，将超时时间设置为300秒（5分钟）
• 切换国内CRAN镜像：先运行options(repos = c(CRAN="https://mirrors.tuna.tsinghua.edu.cn/CRAN/"))，再执行安装命令，国内镜像下载速度更快
• 本地手动安装：下载对应版本的terra二进制包（zip格式），执行install.packages("你的本地文件路径/terra_1.7-71.zip", repos = NULL, type = "win.binary")完成安装
