By default, Bundler installs gems into a shared location, but they can also be installed directly into your application.
You can mitigate this issue by encapsulating the code into separate classes–which solves the reuse problem–but this solution only scales to a certain point. Bundler solves these problems to some extent by packaging gems into your application. Bundler allows you to specify which gems your application depends upon, and optionally which version those gems should be.Once this specification is in place, Bundler installs all required gems (including the full gem dependency tree) and logs the results for later inspection.Using a third-party library simply requires downloading the code and putting it into a common location accessible from any program running on your computer. Ruby Gems downloads the gem and installs it into your current Ruby version’s common directory.Then, all of the Ruby applications in your development environment that use the current version of Ruby will have access to the new gem’s functionality.Please note, we are currently updating the 2018 Journal Metrics.
GEM – The International Journal on Geomathematics publishes peer-reviewed mathematical papers that deal with (i) modelling of the system Earth (geosphere, cryosphere, hydrosphere, atmosphere, biosphere) (ii) analytic, algebraic, and operator-theoretic methods, (iii) computational and numerical analysis methods necessary for the mathematical treatment of geoscientifically relevant problems, and (iv) survey articles bridging Geosciences and Mathematics.
In Ruby, we address this issue by using third-party libraries known as Gems.
Ruby Gems are sets of code that implement common functionality.
In those cases, you might want to uninstall these gems to prevent too much unused cruft from building up in your Ruby install.
To uninstall a gem, use the following command (where .
We’ll also take a look at managing gem sources, giving you more options to install additional functionality libraries from various third parties.
