从GitHub安装R包报错Error: Failed to in

从GitHub安装R包报错Error: Failed to install 'Rpackage' from GitHub: Does not appear to be an R package (no DESCRIPTION)

一、问题：

前天在办公室电脑上安装上了“四个万能包”生信技能树良心佳作-Jimmy的四个万能R包；昨天在自己电脑上安装生信技能树良心佳作-Jimmy的四个万能R包

报错如下：Error: Failed to install 'idmap2' from GitHub:
Does not appear to be an R package (no DESCRIPTION)
搜索了一下，这个报错还是挺常见的，看了很多推文没有找到这一问题的解决办法。

二、从GitHub上安装R包的方法

首先，要了解从Github上装R包的方法：

主要有两种:

第一种：

library(devtools)
install_github("xx.Rpackage")

第二种：

BiocManager::install('githubinstall')
library(githubinstall)

githubinstall("xx.Rpackage")

从GitHub安装R包当然还有其他方法，更多细节可以参考下列推文：

三、解决方法

尝试各种安装方法，看报错信息，发现报错信息都一样。

library(devtools)
install_github("jmzeng1314/idmap2")
Downloading GitHub repo jmzeng1314/idmap2@master
jmzeng1314-idmap2-cd335d6/data/GPL10333.rda: truncated gzip input
tar.exe: Error exit delayed from previous errors.
Error: Failed to install 'idmap2' from GitHub:
  Does not appear to be an R package (no DESCRIPTION)
In addition: Warning messages:
1: In utils::untar(tarfile, ...) :
  ‘tar.exe -xf "C:\Users\ljx\AppData\Local\Temp\Rtmp4yLw2n\filea2c30364ca.tar.gz" -C "C:/Users/ljx/AppData/Local/Temp/Rtmp4yLw2n/remotesa2c439e24db"’ returned error code 1
2: In system(cmd, intern = TRUE) :
  running command 'tar.exe -tf "C:\Users\ljx\AppData\Local\Temp\Rtmp4yLw2n\filea2c30364ca.tar.gz"' had status 1

今天花费了两个多小时才解决，尝试了如下的方法：

install_github("jmzeng1314/idmap2")

library(idmap2)

BiocManager::install('githubinstall')
library(githubinstall)

githubinstall("jmzeng1314/idmap2")

devtools::install_github("jmzeng1314/idmap2", subdir = "pkg")
devtools::install_github('jmzeng1314/idmap2')

idmap2 = devtools:::source_pkg("idmap2-master")
install(idmap2)

githubinstall("idmap2")
githubinstall::idmap2
githubinstall::githubinstall("idmap2")

以上安装全部失败。

四、终极解决办法：本地安装

终极解决办法：本地安装

devtools::install_local("idmap2.zip")

> devtools::install_local("idmap2.zip")
