我正在尝试在 Ubuntu Saucy 上安装 gsl gem

我安装了相关的gsl包

sudo apt-get install gsl-bin libgsl0-dev

但随后安装 gem 失败

问题和这个类似：Problems installing gsl gem

尽管该线程的顶级解决方案不起作用 - gsl 1.14 的源包在该地址不再可用。我想这对许多使用 Saucy 的用户会有用。

标签： ruby ubuntu gsl ubuntu-13.10

【解决方案1】：

linked 问题中接受的答案在13.10 中为我解决了这个问题，并进行了一些小的更改。

curl -O  ftp.unicamp.br/pub/gnu/gsl/gsl-1.14.tar.gz 
tar xvzf gsl-1.14.tar.gz
cd gsl-1.14
./configure
make
sudo make install
sudo gem install --conservative --no-ri --no-rdoc gsl

显然，从“任何 FTP 服务器”安装软件包时应该小心 :)
