在CentOS中安装软件包时出错:无法加载因特网例程
在CentOS中安装软件包时出错:无法加载因特网例程
提问于 2016-04-22 21:55:22
在更新R之后，我在CentOS上安装软件包时遇到了一些问题。下面是一个示例，说明当我试图在R中安装一个软件包时会发生什么：
> install.packages("ggplot2")
Installing package into '/home/albers/R/x86_64-pc-linux-gnu-library/3.2'
(as 'lib' is unspecified)

package 'ggplot2' is not available (for R version 3.2.5)所以我花了一些时间搜索错误信息。我更新了我的卷发版本，现在是最新的：
$ curl -V

Protocols: dict file ftp gopher http imap pop3 rtsp smtp telnet tftp
Features: IPv6 Largefile libz UnixSockets仍然无法安装软件包，并且正在收到相同的错误消息。因此，我尝试遵循this post的说明，特别是将以下命令添加到.bash_profile中
export LD_LIBRARY_PATH=$TOOLS/curl-7.48.0/lib:$LD_LIBRARY_PATH同样，我得到了关于R无法加载共享对象的相同错误消息。最终，这是一个下载问题，因为download.file也失败了。这是我的sessionInfo()

有人对我如何解决这个问题有什么建议吗？

像这样试试。
install.packages("ggplot2", repos="http://cran.cnr.berkeley.edu")或者，在安装它之前，将下载工具更改为其他工具(在Linux上)，您可以尝试wget，如下所示。
options(download.file.method = "wget")注意，我已经删除了https for http。我也犯了类似的错误..。

Yours
Protocols: dict file ftp gopher http imap pop3 rtsp smtp telnet tftp
Mine (Also Centos 6)
Protocols: tftp ftp telnet dict ldap ldaps http file https ftps scp sftp 您的curl缺少https支持。您的输出中也有一个关于curl_multi_wait的错误。这是在7.28.0中添加的。
如果需要在本地构建curl，请执行以下操作
mkdir -p $HOME/curl
cd $HOME/curl
git clone https://github.com/curl/curl.git
cd curl
bash buildconf
./configure --prefix=$HOME/libcurl
make
make install此时，您需要在LD_LIBRARY_PATH ie中设置.bash_profile
export LD_LIBRARY_PATH=$HOME/libcurl/lib:$LD_LIBRARY_PATH然后要么退出，然后再回来，要么

我相信在去年夏天R3.2升级之前，我曾回答过一个类似的问题。使用Ubuntu12.04的Travis CI也有类似的问题。
一个非常简单的方法就是告诉R使用外部的wget或curl二进制文件来下载(这需要https准备好)。所以试一试
R> options("download.file.method"="wget")设置后，我可以从所需的非https主机下载所需的包：
R> install.packages("ggplot2", repos="http://cran.cnr.berkeley.edu")
