R devtools not available for R 3.0.1?

Question

After installing Rtools30, devtools installation will fail on a 32-bit Windows 7 system:

install.packages("C:/Users/hharmsen/Downloads/devtools_1.2.zip", repos = NULL) Warning in install.packages : package 'C:/Users/hharmsen/Downloads/devtools_1.2.zip' is not available (for R version 3.0.1) 

When installing directly, devtools seems to install correctly, but an error occurs on boot:

 install.packages('devtools') library(devtools) WARNING: Rtools 3.0 found on the path at c:/Rtools is not compatible with R 3.0.1. Please download and install the appropriate version of Rtools from http://cran.r-project.org/bin/windows/Rtools/, remove the incompatible version from your PATH, then run find_rtools(). 

However, installing devtools on R 3.0 does not have a problem on a 64-bit Debian system. Also, Rtools must be compatible [R> 2.15.1 to R 3.0.x]. Does anyone know how to solve this?

Answer 1

You specified the absolute path and file on install.packages() , maybe the file is in the wrong place?

As the corresponding webpage is explained, your first attempt should be

  install.packages("devtools") 

since this is a CRAN package.
