rtools 报错

step 1：bug 是什么

WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

step 2：原因这是 rtools 没有安装或者版本不匹配，需要下载 rtools RTools: Toolchains for building R and R packages from source on Windows (r-project.org)

step 3：下载对应的 rtools

我下的是 R 4.3.3，所以下载

Lib 没有指定问题

永久指定下载包的路径

因为我的 R 语言下载在 D 盘，想要下载包到 D 盘的library

.libPaths ()
.libPaths ("D:/Software/R-4.3.3/library")
