我在Ubuntu机器13.10上安装XML和RCurl时遇到了一些麻烦。我今天进行了所有sudo更新和升级。
我正在尝试为R使用拨浪鼓。我无法安装使用拨浪鼓所需的“XML”。这与一年后right here和另一个操作系统提出的问题几乎相同。以下是我要回复的错误消息：

不太确定如何从这里开始。

在Ubuntu上安装curl和xml。运行
sudo apt-get install libcurl4-openssl-dev libxml2-dev
R中包安装的错误消息表明curl和xml库不存在或无法找到。

在CentOS 6+中，您可以使用
进行操作sudo yum -y install curl
sudo yum -y install libcurl libcurl-devel
sudo yum -y install libxml2 libxml2-devel

对于不能使用KeyError Traceback (most recent call last)

或yum安装的用户，我分享我的经验：
我通过下载源代码并进行编译来自己安装apt-get。不过，我仍然遇到libcurl-openssl-dev问题。直到查看RCurl源代码并看到引用了Cannot find curl-config环境变量，我才知道该怎么做。我尝试将自己设置为CURL_CONFIG，但似乎可行：
.bashrc

对于 ubuntu 18.05 有时存储库有问题运行如下
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
