在R版本3.4.1 32位Debian中安装swirl时出错

Question

我试图在Debian wheezyx上安装RV3.4.1 32位中的swirl，但得到了错误。如下所示：

 ------------------------- ANTICONF ERROR ---------------------------
 Configuration failed because libcurl was not found. Try installing:
 * deb: libcurl4-openssl-dev (Debian, Ubuntu, etc)
 * rpm: libcurl-devel (Fedora, CentOS, RHEL)
 * csw: libcurl_dev (Solaris)
 If libcurl is already installed, check that 'pkg-config' is in your
 PATH and PKG_CONFIG_PATH contains a libcurl.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=...'
 --------------------------------------------------------------------
 ERROR: configuration failed for package 'curl'
 * removing '/usr/local/lib/R/site-library/curl'

 Using PKG_LIBS=-lssl -lcrypto
 ------------------------- ANTICONF ERROR ---------------------------
 Configuration failed because openssl was not found. Try installing:
 * deb: libssl-dev (Debian, Ubuntu, etc)
 * rpm: openssl-devel (Fedora, CentOS, RHEL)
 * csw: libssl_dev (Solaris)
 * brew: openssl@1.1 (Mac OSX)
 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=...'
 --------------------------------------------------------------------

然后我尝试安装libcurl4-openssl-dev，但得到以下错误。我不知道下一步该怎么做。

 > install.packages("libcurl4-openssl-dev")
 Installing package into '/usr/local/lib/R/site-library'
 (as 'lib' is unspecified)
 Warning message:
 package 'libcurl4-openssl-dev' is not available (for R version 3.4.1)

我尝试以Debian包的形式安装libcurl4-openssl-dev，这是我收到的输出。

 Setting up dropbear (2014.65-1+deb8u2) ...

在我运行包之后，这个问题仍然存在。

从终端第一次尝试：

sudo apt-get install libcurl4-openssl-dev libssl-dev

稍后，返回到Rstudio并再次安装swirl包。
