R 3.0.2上的install.packages（“devtools”）在Ubuntu 14.04中失敗

Question

我試圖在Ubuntu 14.04上安裝R 3.0.2 devtools包，如下所示：

install.packages("devtools")

我得到以下結果：

Installing package into ‘/home/jim/R/x86_64-pc-linux-gnu-library/3.0’

似乎存在對名為xml2的包的依賴性。 有誰知道我在哪里可以找到這個包以及如何安裝它。

我已經安裝了以下內容：

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

Answer 1

如果使用軟件中心在Ubuntu中安裝R，則包含構建Ubuntu構建時的穩定版本。 因此安裝了R 3.0.2。

將以下內容添加到/etc/apt/sources.list：

deb http://cran.rstudio.com/bin/linux/ubuntu trusty/

導致當前版本（R 3.2.0）被加載。

我必須安裝以下OpenSSL庫

sudo apt-get install libssl-dev

然后我就能啟動R並成功安裝'devtools'

非常感謝Dirk和Pascal的建議。

Answer 2

另一個解決方案（在版本R 3.2.2上）是安裝lxml：

$ apt-get install libxml2-dev libxslt-dev

哪個成功刪除了R錯誤：

錯誤：包'xml2'的配置失敗

跑步時出現在R中

install.packages（注明 “DevTools”）
