我正在尝试在Ubuntu Saucy上安装gsl gem
我用
安装了相关的gsl包sudo apt-get install gsl-bin libgsl0-dev
然后安装gem失败

问题与此类似:Problems installing gsl gem
该线程的顶级解决方案不起作用 - gsl 1.14的源包不再可用于该地址。我想这对Saucy的许多用户都很有用。
答案 0 :(得分:1)
linked问题上的已接受答案在13.10
中为我解决了此问题,并进行了一些细微更改。
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,应该小心从“任何FTP服务器”安装软件包:)
