添加ldconfig寻找路径

include /etc/ld.so.conf.d/.conf
进入/etc/ld.so.conf.d目录内，创建.conf文件,文件名随意，扩展名必须为.conf
sudo ldconfig

ldconfig -p | grep libpng

--------------------------- [ANTICONF] --------------------------------
Configuration failed to find the harfbuzz freetype2 fribidi library. Try installing:
 * deb: libharfbuzz-dev libfribidi-dev (Debian, Ubuntu, etc)
 * rpm: harfbuzz-devel fribidi-devel (Fedora, EPEL)
 * csw: libharfbuzz_dev libfribidi_dev (Solaris)
 * brew: harfbuzz fribidi (OSX)
If harfbuzz freetype2 fribidi is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a harfbuzz freetype2 fribidi.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=...'
