我正在尝试构建R包png，该仓库说libpng需要可用。
我运行Linux Fedora 20版本
看起来我有...
[root@localhost bin]# yum install libpng
Loaded plugins: langpacks, refresh-packagekit
Package 2:libpng-1.6.3-3.fc20.x86_64 already installed and latest version
Nothing to do
但是当我尝试安装它时：
> install.packages("png")
Installing package into ‘/home/statquant/R/x86_64-redhat-linux-gnu-library/3.0’

最佳答案
对于某些R软件包，您需要相应的开发库才能成功安装R软件包。在你的情况下，这应该做你需要的
# Do the following in your terminal (not in an R session)
yum install libpng-devel
之后，您应该能够安装R软件包
# Do the following in the R console (during an R session)
install.packages("png")
