麻烦：网络程序无法加载

我有一些麻烦更新R.这里后，在CentOS R中安装软件包

是的，当我尝试R中安装一个软件包会发生什么一个例子：麻烦：网络程序无法加载

所以我花了一些时间搜索错误消息。我更新了我现在最新版本的卷曲：

$ curl -V 
curl 7.48.0 (x86_64-pc-linux-gnu) libcurl/7.48.0 zlib/1.2.8 
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，并且收到相同的错误消息。所以我尝试以下的this post的指示，具体地添加以下命令到我.bash_profile：

export LD_LIBRARY_PATH=$TOOLS/curl-7.48.0/lib:$LD_LIBRARY_PATH

我再次获得关于R无法加载共享对象相同的错误消息。最终，这是一个下载问题，因为download.file也失败了。这里是我的sessionInfo()：

我能够下载与wget和curl但只要我开始R，我无法下载任何文件。

有没有人有任何建议我可以解决这个问题？

像这样尝试。

install.packages("ggplot2", repos="http://cran.cnr.berkeley.edu")

或只是你安装它改变你的下载工具到别的东西，即在Linux上，你可以尝试的wget如下之前。

options(download.file.method = "wget")

注意，我为http扔下https。我有一个类似的错误...

Selection: 1 
Warning: unable to access index for repository https://cran.rstudio.com/src/contrib: 
    unsupported URL scheme 
Warning message: 
package ‘ggplot2’ is not available (for R version 3.2.3)

如果你看看从你的问题下面一行的输出...

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

你curl缺少https支持。在您的输出中也有关于curl_multi_wait的错误。这是在7.28.0中添加的。

https://curl.haxx.se/libcurl/c/curl_multi_wait.html

如果你需要建立本地卷曲做到这一点

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

此时你需要设置你的LD_LIBRARY_PATH中的.bash_profile即

export LD_LIBRARY_PATH=$HOME/libcurl/lib:$LD_LIBRARY_PATH

然后要么注销和背部再次或

source ~/.bash_profile

我相信在去年夏天进行R 3.2。*升级之前，我曾回答过类似的问题。使用Ubuntu 12.04的Travis CI有类似的问题。周围

一个相当简单的方法就是让R能够使用外部wget或curl二进制你可能有（且必须是HTTPS就绪）下载。因此，尝试如

R> options("download.file.method"="wget")

其中，设定时，可以让我从所需的非HTTPS主机下载你想要的包：

R> install.packages("ggplot2", repos="http://cran.cnr.berkeley.edu")
