在RStudio 3.1.2中安装swirl时出错

Question

嘿，我试着用下面的命令安装swirl：

install.packages("swirl")

我得到了以下错误：

    ------------------------- 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=...'

The downloaded source packages are in
    ‘/tmp/Rtmp7G87EM/downloaded_packages’

我尝试安装"curl“和"RCurl”包，但得到了相同的错误消息。我不知道如何按照ANTICONF错误中的指示更改路径。

我正在运行Ubuntu 15.04和R版本3.1.2 (2014-10-31)

Answer 1

现在它是

sudo apt-get install libcurl4-gnutls-dev

Answer 2

2019年5月30日更新:我使用的是Ubuntu 16.04

这是我在安装软件包时得到的--使用PKG_CFLAGS=

配置失败，因为找不到openssl。尝试安装：* deb: libssl-dev (Debian，Ubuntu等)* rpm: openssl-devel (Fedora，CentOS，RHEL) * csw: libssl_dev (Solaris) * brew: openssl@1.1 (Mac )如果openssl已经安装，请检查'pkg-config‘是否在您的路径中，以及PKG_CONFIG_PATH是否包含openssl.pc文件。如果pkg-config不可用，您可以通过以下命令手动设置INCLUDE_DIR和LIB_DIR :R INSTALL --configure-vars=‘INCLUDE_DIR... LIB_DIR=...’

我在终端中使用了命令>

sudo apt-get install libssl-dev

然后它就运行得很好了。
