我最近升级到R 3.5并且无法安装'tidyverse'软件包。其他包安装正常。每当我尝试安装tidyverse时，我收到以下错误消息。
* installing *source* package ‘curl’ ...
** package ‘curl’ successfully unpacked and MD5 sums checked
Found pkg-config cflags and libs!
Using PKG_CFLAGS=-I/usr/include/x86_64-linux-gnu

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

我已经运行sudo apt-get install libcurl4-openssl-dev，就像其他线程上针对同一问题所建议的那样。但是，这似乎没有解决问题（事实上，已经安装了libcurl，并且重新安装它也无效）。
当我检查$ PATH时，我没有看到'pkg-config'，并且PKG_CONFIG_PATH似乎不存在。将/usr/bin/pkg-config添加到路径并设置PKG_CONFIG_PATH /home/nik/anaconda3/lib/pkgconfig/libcurl.pc似乎也没有解决问题。我现在处于智慧状态，因为我无法想到卸载/重新安装的任何其他内容，也没有弄清楚为什么在我安装时没有将libcurl添加到路径中。任何帮助都将不胜感激。
尝试设置包含libcurl的目录的路径，而不是libcurl本身，即
PKG_CONFIG_PATH=/home/nik/anaconda3/lib/pkgconfig
