最近，我开始使用Rstudio学习R语言，但是当我打算安装一些软件包时，我遇到了一些问题。
当我尝试安装＆＃34; rvest＆＃34;包，它给出如下错误：
> install.packages("rvest")Installing package into ‘/home/zm/R/x86_64-pc-linux-gnu-library/3.4’

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=...'

我认为以下是我的问题的关键点：
配置失败，因为找不到openssl。
我尝试安装：
如果已安装openssl，请检查＆＃39; pkg-config＆＃39;在你的 PATH和PKG_CONFIG_PATH包含openssl.pc文件。
如果pkg-config不可用，您可以通过以下方式手动设置INCLUDE_DIR和LIB_DIR：
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
我也开始在Ubuntu中安装软件包。但是，我甚至没有成功在Ubuntu中安装它们。
我还尝试了以下方法：export PKG_CONFIG_PATH=/cv/lib:$PKG_CONFIG_PATH
没有成功..
有人可以帮我弄清楚发生了什么，非常感谢你！

我和你有同样的问题。 你需要做一些事情（核选项，但它应该工作）：
sudo add-apt-repository 'deb
https://mirrors.nic.cz/R/bin/linux/ubuntu trusty/'
sudo apt-get update
sudo apt-get install r-base-dev
sudo apt-get install libxml2-dev
sudo apt-get install libssl-dev
sudo -i R
sudo -i rstudio
并在R：
install.package('rvest')
我做了以上所有事情，也许
pkg-config rvest
在控制台中，它工作正常。在程序包安装过程中显示一些标题为“你可以看到”反基因错误“的消息，并且应该写下你应该安装的其他内容。我的清单包括那些包裹。 我看到自你的请求以来已经过了一段时间，但是为了下一代的缘故，应该回答它。

只需使用aptitude或apt安装libssl-dev 按照您报告的错误消息中所述。
在尝试安装tidyverse软件包时，我也遇到了无法从OSX上的rstudio安装openssl的问题。
对我来说，解决方案是尝试从r提示符下安装openssl， 然后，我从外壳程序的“-ANTICONF ERROR-”下收到了指令：

对于OSX下的我来说，我只需要使用软件包管理器来安装openssl@1.1
brew install openssl@1.1
然后我可以从R中正常安装tidiverse，然后从rstudio中使用它。
因此，我相信一旦您将使用
之类的东西从shell中安装了libssl-dev，您就应该能够从Rstudio安装rvest。aptitude install libssl-dev
或类似的apt命令
