无法构建R包"png"浅顶软呢帽20 [英] Cannot build R package "png" Fedora 20

问题描述

我正在尝试构建R包 png ，则仓库说libpng需要可用.

I am trying to build the R package png, the repo says that libpng needs to be available.

我运行Linux Fedora 20发行版

I run a Linux Fedora 20 distro

好像我有...

[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:

But when I try to install it:

推荐答案

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.在您的情况下，这应该可以满足您的需求

For some R packages you need the corresponding development library to successfully install the R package. In your case this should do what you need

# 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

afterwards you should be able to install the R package

# Do the following in the R console (during an R session)
install.packages("png")
