![Ubuntu Saucy(13.10)上的 Gsl ruby gem](https://linux22.com/image/1043810/Ubuntu%20Saucy%EF%BC%8813.10%EF%BC%89%E4%B8%8A%E7%9A%84%20Gsl%20ruby%E2%80%8B%E2%80%8B%20gem.png)
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
但安装 gem 失败

该问题与此类似:安装 gsl gem 时出现问题
但是该线程中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 的用户来说会很有用。

对于 ubuntu 13.10,ruby 2.0.0 可以正常工作-
curl -O http://ftp.unicamp.br/pub/gnu/gsl/gsl-1.16.tar.gz
tar xvzf gsl-1.16.tar.gz
cd gsl-1.16
./configure
make
sudo make install
sudo gem install --conservative --no-ri --no-rdoc gsl
