install_github返回错误:zip文件无法打开

Question

当我运行以下:

library(devtools)
install_github('roxygen2')

我得到以下错误:

与devtools0.51:

Installing roxygen2 from hadley
Error in unzip(src, list = TRUE) : 
  zip file '/tmp/Rtmp2b44Ug/hadley-roxygen2.zip' cannot be opened

我安装了最新版本（0.6）的devtools: install_github('devtools')

并且错误更具信息性，但类似:

> install_github('roxygen')
Installing github repo(s) roxygen/master from hadley
Installing roxygen.zip from https://github.com/hadley/roxygen/zipball
Error in expand(src, list = TRUE) : 
  zip file '/tmp/Rtmp2b44Ug/roxygen.zip' cannot be opened
In addition: Warning message:
In expand(src, exdir = tempdir()) : error 1 in extracting from zip file

我做错什么了吗？

Answer 1

发生此错误是因为函数 install_github 套件 username='hadley' 默认情况下（见 安装-github。r源)

在这种情况下，没有github分支 hadley/roxygen, ，现在从下载 https://github.com/hadley/roxygen/zipball/master

这将工作:

install_github('roxygen',username = 'klutometis')

注意事项: 即使软件包被称为roxygen2，"repo"名称也是"roxygen"
