从github安装包时出错
[英]Error installing packages from github
问题描述
I can't install packages from github: 
我无法从github安装包：
> install_github('cranvas', 'ggobi', args="--no-multiarch")
Installing github repo(s) cranvas/master from ggobi
Installing cranvas.zip from https://github.com/ggobi/cranvas/archive/master.zip
Error in function (type, msg, asError = TRUE) : couldn't connect to host
this is my session: 这是我的会议：
R version 3.0.1 (2013-05-16)
Platform: x86_64-pc-linux-gnu (64-bit)
NB: install.packages works as usual, it's just with github the issue. 注意： install.packages像往常一样工作，它只是与github问题。 Have some of you ever faced this? 有没有人遇到过这个？ Thanks 谢谢

Some users have run into the following error when using the instructions above: Error in function (type, msg, asError = TRUE) : couldn't connect to host. 使用上述说明时，某些用户遇到以下错误：函数错误（type，msg，asError = TRUE）：无法连接到主机。 This is likely due to the use of proxies (which would prevent you from installing any package from github), and can be rectified using the httr package. 这可能是由于使用代理（这会阻止您从github安装任何软件包），并且可以使用httr软件包进行纠正。 Run the following commands before install_github(...) above: 在上面的install_github（...）之前运行以下命令：
install.packages("httr")
library(devtools)
library(httr)
set_config(use_proxy(url="http://proxyname.company.com",port=8080,username="XXX",password="XXX"))
install_github("cranvas")
Hope this helps. 希望这可以帮助。

GitHub no longer supports HTTP. GitHub不再支持HTTP。 That was disabled quite some years ago and it may have been aligned with mitigation of FireSheep . 这种情况在几年前就被禁用了，它可能与缓解FireSheep有关 。 My test was as follows: 我的测试如下：
curl -i http://github.com/ggobi/cranvas/archive/master.zip
HTTP/1.1 301 Moved Permanently
Server: GitHub.com
