我正在尝试在 R 上安装 S3 包，以便保存我正在运行的回归的 csv 输出。我尝试安装 S3 软件包以将 Rstudio 服务器链接到 S3，但没有成功。这是我在尝试安装 aws.s3 包时收到的错误:

If openssl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a openssl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

安装 openssl 软件包时也是如此。我的 EC2 实例类型是 t2.medium。
最佳答案
这里，在安装cloudyr的aws.s3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。这些又依赖于 libssl、libxml2 和 libcurl4-openssl 操作系统库。
在一个全新的 EC2 实例上，假设是 Ubuntu 机器(当然，Fedora/CentOS/RedHat 发行版也有等效的 yum 软件包)，必须首先安装操作系统依赖项:
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"))
希望这有帮助
