編譯R包samr時出錯：`ld：找不到-lgfortran的庫

我試着install.packages("samr")，但它看起來像是試圖使用Fortran編譯文件，但我的Fortran看起來並沒有在指定的路徑上安裝程序，我的Fortran是從brew install gcc（我相信正確的路徑是/usr/local/Cellar/gcc/7.1.0/lib/gcc/7）。這是我的錯誤：編譯R包samr時出錯：`ld：找不到-lgfortran的庫

它看起來像環境特定的問題。我使用的日常R上3.3.3，我能夠沒有任何問題，安裝軟件包：

# 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)

不過，我使用略有不同的安裝gfortran的 - 直接從源：

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

gfortran --version 
GNU Fortran (GCC) 6.3.0 
Copyright (C) 2016 Free Software Foundation, Inc. 
This is free software; see the source for copying conditions. There is NO 
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

，這就是gfortran的位置，同時從項目頁面安裝它

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

也許你可以嘗試從項目頁面安裝它？不幸的是，在macOS的情況下，在R包（尤其是Java和Fortran）中有很多有力的假設。

感謝您的回答我基本上做了同樣的事情，它的工作。在此之前，我還嘗試從他們的頁面直接下載並安裝它，但一直存在版本問題。但按照gcc.gnu.org的規定安裝gfortran似乎是解決方案。 –

從gcc.gnu.org安裝gfortran爲我工作。 – jsb
