R 卷曲包未安装

安装curl包时

install.packages("curl")
Installing package into ‘/home/mrshekar/R/x86_64-pc-linux-gnu-library/3.4’
(as ‘lib’ is unspecified)
trying URL 'https://cloud.r-project.org/src/contrib/curl_3.2.tar.gz'

* installing *source* package ‘curl’ ...
** package ‘curl’ successfully unpacked and MD5 sums checked
’

在此之后，我从安装了libcurl包。然后我还将整个packae文件夹复制到r的library文件夹中。安装curl包时，仍然会出现错误

    **Configuration failed because libcurl was not found**. Try installing:

     * rpm: libcurl-devel (Fedora, CentOS, RHEL)

    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=...'

我错在哪里？不同的软件包，如shiny和ggplot，都是以相同的方式下载和加载的。有人能帮忙吗？

之所以会发生这种情况，是因为我必须最终安装quantmod软件包，但它提供了无法安装curl依赖项的信息

libcurl4 openssl dev不是一个R软件包，而是一个linux库

在控制台类型中：

sudo apt-get install libcurl4-openssl-dev

注意：您需要sudo权限
