linux - install.packages ("devtools") 在 R 3.0.2 上在 Ubuntu 14.04 中失败

Question

我正在尝试在 Ubuntu 14.04 上安装 R 3.0.2 devtools 包，如下所示:

install.packages("devtools")

我得到以下结果:

Installing package into ‘/home/jim/R/x86_64-pc-linux-gnu-library/3.0’
(as ‘lib’ is unspecified)

似乎依赖于名为 xml2 的包。有谁知道我在哪里可以找到这个软件包以及如何安装它。

我已经安装了以下内容:

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

如果使用软件中心在 Ubuntu 中安装 R，则包含构建 Ubuntu 时的稳定版本。因此安装了 R 3.0.2。

将以下内容添加到/etc/apt/sources.list:

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

导致加载当前版本 (R 3.2.0)。

我必须安装以下 OpenSSL 库

sudo apt-get install libssl-dev

然后我能够启动 R 并成功安装“devtools”

非常感谢 Dirk 和 Pascal 的建议。
