“非零退出状态” R 3.0.1“ XML”和“ RCurl”

Question 1

我在Ubuntu 13.10机器上安装XML和RCurl时遇到了一些麻烦。我今天执行了所有sudo更新和升级。

我正在尝试将拨浪鼓用于R。我无法安装使用拨浪鼓所需的“ XML”。这是相当多的这是问同样的问题在这里仅仅一年后和不同的操作系统。以下是我返回的错误消息：

不太确定如何从这里继续。

Question 2

在Ubuntu上安装curl和xml。跑

sudo apt-get install libcurl4-openssl-dev libxml2-dev

R中安装的软件包上的错误消息表示curl和xml库不存在或找不到。

Question 3

在CentOS 6+中，您可以使用

sudo yum -y install curl
sudo yum -y install libcurl libcurl-devel
sudo yum -y install libxml2 libxml2-devel

Question 4

对于无法使用yum或安装的用户apt-get，我分享我的经验：

我libcurl-openssl-dev通过下载源代码并进行编译来安装自己。不过，我仍然遇到Cannot find curl-config问题...在查看RCurl源代码并看到CURL_CONFIG引用了环境变量之前，我不知道该怎么做。我尝试将.bashrc它设置为自己的方法，但似乎可行：

export CURL_CONFIG=~/my/libcurl/curl-config

Question 5

对于ubuntu 18.05有时存储库存在如下问题

在sudoedited行中添加以下存储库

deb http://security.ubuntu.com/ubuntu仿生安全性主要

sudoedit /etc/apt/sources.list 
sudo apt-get update
sudo apt-get install libcurl4-openssl-dev --fix-broken
sudo apt-get install libcurl4-openssl-dev libxml2-deve
