Question

我正在尝试install.packages("samr")，但看起来它试图使用Fortran编译文件，但我的Fortran似乎不在安装程序指定的路径上，我的Fortran来自brew install gcc（我相信正确的路径是/usr/local/Cellar/gcc/7.1.0/lib/gcc/7）。这是我的错误消息：

install.packages("samr")
--- Please select a CRAN mirror for use in this session ---
Package which is only available in source form, and may need

Do you want to attempt to install these from sources?

看起来像环境特定的问题。我每天都在使用R 3.3.3，我能够毫无问题地安装软件包：

# this one is required by samr and is no longer available via CRAN
source("https://bioconductor.org/biocLite.R")
biocLite("impute")
# samr, itself, can be installed from CRAN
install.packages("samr")
library(samr)

但是，我正在使用稍微不同的gfortran安装 - 直接来自源：

https://gcc.gnu.org/wiki/GFortranBinaries

gfortran --version
GNU Fortran (GCC) 6.3.0
Copyright (C) 2016 Free Software Foundation, Inc.

这是gfortran从项目页面安装时的位置

> which gfortran
/usr/local/bin/gfortran
> ls -l /usr/local/gfortran/lib/gcc/x86_64-apple-darwin16/6.3.0/ | wc -l
      20

也许您可以尝试从项目页面安装它？不幸的是，在macOS的情况下， R 包中有很多强大的假设（特别是对于Java和Fortran）。

编译R包samr时出错：`ld：找不到-lgfortran`的库
