在使用install.packages（“ DMwR”）时，它给出“软件包DMwR具有非零退出状态”。我想使用需要此软件包的knnImputation函数。我当前正在使用ubuntu 16.04。我需要其帮助安装。 运行install.packages（“ DMwR”）的完整错误堆栈如下所示：
install.packages("DMwR",dependencies = TRUE)

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=...'
