Question

我正在尝试在R上安装S3软件包，以便将cv输出保存到我正在运行的回归中。我尝试安装S3软件包以将Rstudio服务器链接到S3，但是没有运气。这是我在尝试安装aws.s3软件包时收到的错误：

> install.packages("aws.s3", repos = c("cloudyr" = "http://cloudyr.github.io/drat"))

然后我尝试安装httr依赖软件包，但也没有成功。

类似，在安装openssl软件包时。我的EC2实例类型是t2.medium。

Answer 1

在这里，在安装cloudyr的aws.s3软件包之前，需要一些操作系统和一些R依赖项。

aws.s3依赖于三个R包：curl，httr和xml。这些依次取决于libssl，libxml2和libcurl4-openssl OS库。

在全新的EC2实例上，假设使用Ubuntu机器（当然，还有Fedora / CentOS / RedHat发行版的等效yum软件包），则必须首先安装OS依赖项：

sudo apt-get install -y build-essential libssl-dev libxml2-dev libcurl4-openssl-dev

然后，您可以按照指定的顺序安装以下R软件包：

install.packages('curl')
install.packages('httr')
install.packages('xml2')
install.packages("aws.s3", repos = c("cloudyr" = "http://cloudyr.github.io/drat"))

希望这会有所帮助
