安装gsl gem的问题
我可以在我的主目录中成功安装gsl库，但是当我尝试安装gsl gem时，我得到了一个我不理解的大错误列表。 我想知道是否有人可以告诉我为什么我会得到这些错误。 我可以说我有：
成功安装gsl; 至少那是它的样子。 我指出了gsl-config的路径
这是错误日志的样子：

安装ruby GSL：
Ubuntu 11.10包含一个与ruby / gsl不兼容的libgsl0的更新版本（1.15） ：
必须安装旧版本1.14 for ruby / gsl才能工作：
curl -O http://mirror.veriportal.com/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
安装工作正常并在Ubuntu和Debian Squeeze上进行测试：
Fetching: narray-0.6.0.1.gem (100%) Building native extensions. This could take a while... Fetching: gsl-1.14.7.gem (100%) Building native extensions. This could take a while... Successfully installed narray-0.6.0.1 Successfully installed gsl-1.14.7 2 gems installed
你在哪个操作系统？
首先，您需要在您的操作系统上以root身份安装gsl和gsl-devel RPM …例如在Fedora Linux上：
sudo yum install -y gsl gsl-devel
然后执行gem install gsl或bundle install
如果没有gsl-devel包，它将找不到正确的C-header文件。
您还需要确保这些头文件安装在LD_LIBRARY_PATH中包含的位置，或者在/etc/ld.so.conf中列出
如果你有：
- GSL 1.16 （使用
gsl-config --version检查）（例如在Ubuntu 14.04中 ）， - Ruby 2.1
然后尝试https://github.com/siefca/rb-gsl – 它已针对此类配置进行了调整。
它也适用于Ruby 1.9和Ruby 2.0。
如果您使用bundler来管理项目中的gem，那么在Gemfile ：
gem 'gsl', :git => 'git://github.com/siefca/rb-gsl'
干杯!
对于仍然在努力使用gsl_matrix_complex_equal问题进行安装的人。
如果您已经运行brew install gsl ，将在撰写本文时安装1.15，然后尝试安装ruby绑定，您可能会遇到此问题。
使用此repo作为您的rb-gsl gem源解决了这个问题： https ： //github.com/30robots/rb-gsl
但是，如果你有一个更新版本的rubygems，那个repo会调用Gem#searcher ，这是一个已弃用且现已删除的方法。
我的repo更新调用使用Gem::Specification API：
https://github.com/whistlerbrk/rb-gsl
简而言之：
在OSX上brew install gsl
在你的Gemfile中：
gem 'gsl', :git => 'git://github.com/whistlerbrk/rb-gsl.git'
在ubuntu 13.04下，这解决了这个问题：
sudo apt-get install libgsl0-dev
无需手动安装旧版本
注意它似乎不适用于Ruby 2.1.0。
对于Ubuntu 12.04 LTS和Ruby 2.0.0：
cd ~ wget ftp://ftp.gnu.org/gnu/gsl/gsl-1.15.tar.gz tar xvzf gsl-1.15.tar.gz cd gsl-1.15 ./configure make sudo make install
检查GSL 1.15是否安装正确
gsl-config --version
然后安装gem（gsl 1.15.3）
gem install gsl
在我全新安装的Mac OS X Yosemite上 ，我特别需要1.15.3，而自制软件对我来说无法获得（没有brew install gsl115 ）
curl ftp://ftp.gnu.org/gnu/gsl/gsl-1.15.tar.gz > gsl-1.15.tar.gz tar xvzf gsl-1.15.tar.gz cd gsl-1.15 ./configure make sudo make install gem install gsl
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
注意：Ami Navon写道 –
必须安装旧版本1.14才能使用ruby / gsl
现在gsl-1.16 / ruby-2.0.0并不现实
lsb_release -a Ubuntu 14.04.1 LTS
ruby --version ruby 2.1.2p95
重要：安装gsl开发包 （ https://askubuntu.com/a/490475/121418 ）
sudo apt-get install libgsl0-dev
在Gemfile中添加此行
gem 'rb-gsl'
通过终端安装gem
bundle install
校验
bundle show rb-gsl
/.rvm/gems/ruby-2.1.2/gems/rb-gsl-1.16.0.4
gsl-config --version
1.15
如有必要，请在ruby文件中使用require "gsl"
这也适用于ubuntu 16.04 LTS和ruby 2.2.2
sudo apt-get install libgsl0-dev
