我用R i386 3.0.2版本，install.packages一直不成功。
运行install.packages("Rweibo", repos = "http://R-Forge.R-project.org", type="source")时，出现以下错误：
Warning message:
package ‘Rweibo’ is not available (for R version 3.0.2)
运行install.packages("Rweibo", repos = "http://R-Forge.R-project.org")时，出现以下错误：
Error in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :
cannot open the connection
In addition: Warning messages:
1: In download.file(url, destfile, method, mode = "wb", ...) :
downloaded length 57651 != reported length 1150585
2: In unzip(zipname, exdir = dest) : error 1 in extracting from zip file
3: In read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :
cannot open compressed file 'Rweibo/DESCRIPTION', probable reason 'No such file or directory'
求大神指导，这到底是怎么回事啊？怎样才能install成功啊？
