我正在努力在linux centos 7机器上安装png和EBImage R软件包。我总是收到以下错误消息：
Error: package or namespace load failed for ‘png’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/home/rico/R/x86_64-redhat-linux-gnu-library/3.6/00LOCK-png/00new/png/libs/png.so':
libpng16.so.16: cannot open shared object file: No such file or directory
Error: loading failed
Execution halted
ERROR: loading failed
* removing ‘/home/rico/R/x86_64-redhat-linux-gnu-library/3.6/png’
Warning in install.packages :
installation of package ‘png’ had non-zero exit status
The downloaded source packages are in
‘/tmp/RtmpX4o4D5/downloaded_packages’
我试着做：
yum install libpng-devel
它输出我：
Package 2:libpng-devel-1.5.13-7.el7_2.x86_64 already installed and latest version
Nothing to do
知道如何解决这个问题吗？谢谢。
我设法在Linux centos 7计算机上安装了EBImage。sudo cp /usr/local/lib/libpng16.so.16 /usr/lib解决了这个问题
