Gem Dependency Files

In the Edit Project Path Mappings dialog, specify the local and remote project root paths:. After you configured mappings, install gems using the Install Gems to Local Interpreter instruction.

Note that when you are using a remote interpreter, RubyMine downloads gems from a remote machine to a local cache to be able to use code insight features. In this case, you may encounter a situation when new gems were installed on a remote machine outside the IDE.Thanks to RubyGems, we have a rich ecosystem of helpful libraries just one gem install away. A few gems include a Ruby C extension for improved performance.

This extension is built automatically for you when you install the gem, in some cases you may need to manually install additional software that is not managed by RubyGems.

For further reading on signing gems see ri Gem::Security. The check command can list and repair problems with installed gems and specifications and will clean up gems that have been partially uninstalled. The contents command lists the files in an installed gem.

The listing can be given as full file names, file names without the installed directory prefix or only the files that are requireable. The dependency commands lists which other gems a given gem depends on. For local gems only the reverse dependencies can be shown which gems depend on the named gem. The dependency list can be displayed in a format suitable for piping for use with other commands.

The environment command lets you query rubygems for its configuration for use in shell scripts or as a debugging aid. The RubyGems environment can be controlled through command line arguments, gemrc files, environment variables and built-in defaults. The fetch command fetches gem files that can be stored for later use or unpacked to examine their contents.

The given directory will be the directory you serve as the gem repository. It is used to ensure compatibility. Info prints information about the gem such as name, description, website, license and installed paths.

For gems with executables ruby installs a wrapper file into the executable directory by default. This can be overridden with the —no-wrappers option. The wrapper allows you to choose among alternate gem versions using version. RubyGems can install a consistent set of gems across multiple environments using gem install -g when a gem dependencies file gem.

If no explicit file is given RubyGems attempts to find one in the current directory. NOTE: Enabling automatic discovery on multiuser systems can lead to execution of arbitrary code when used from directories outside your control.Install the gems specified in your Gemfile 5. If this is the first time you run bundle install and a Gemfile. If a Gemfile. To apply any of --binstubs--deployment--pathor --without every time bundle install is run, use bundle config see bundle-config 1.

These executables run in Bundler's context. If used, you might add this directory to your environment's PATH variable. On finishing the installation Bundler is going to remove any gems not present in the current Gemfile 5. Don't worry, gems currently in use will not be removed.

In deployment modeBundler will 'roll-out' the bundle for production or CI use. Please check carefully if you want to have this option enabled in your development environment. Force download every gem, even if the required versions are already available locally. Do not allow the Gemfile. Exits non-zero if there are going to be changes to the Gemfile.

Performance can be improved for large bundles that seldom change by enabling this option. The location of the Gemfile 5 which Bundler should use. This defaults to a Gemfile 5 in the current working directory. In general, Bundler will assume that the location of the Gemfile 5 is also the project's root and will try to find Gemfile.

Do not attempt to connect to rubygems. Note that if a appropriate platform-specific gem exists on rubygems. This does not remove any gems in the cache but keeps the newly bundled gems from being cached during the install.

Makes a bundle that can work without depending on Rubygems or Bundler at runtime. A space separated list of groups to install has to be specified.The Gemfile. This also allows you to say "I want to use the current version of nokogiri" gem 'nokogiri' in your Gemfile without having to look up the exact version number, while still getting the benefits of ensuring that your application always runs with exactly the same versions of all third-party code.

Q: I don't understand why I need bundler to manage my gems in this manner. Why can't I just get the gems I need and stick them in submodules, then put each of the submodules on the load path? A: Unfortunately, that solution requires that you manually resolve all of the dependencies in your application, including dependencies of dependencies. And even once you do that successfully, you would need to redo that work if you wanted to update a particular gem.

For instance, if you wanted to update the rails gem, you would need to find all of the gems that depended on dependencies of Rails rackerubisi18ntzinfoetc. Frankly, this is the sort of problem that computers are good at, and which you, a developer, should not need to spend time doing.

gem install gemfile

More concerningly, if you made a mistake in the manual dependency resolution process, you would not get any feedback about conflicts between different dependencies, resulting in subtle runtime errors. For instance, if you accidentally stuck the wrong version of rack in a submodule, it would likely break at runtime, when Rails or another dependency tried to rely on a method that was not present.

Bottom line: even though it might seem simpler at first glance, it is decidedly significantly more complex. Q: I ran bundle install --without production and bundler is still downloading the gems in the :production group.

A: Bundler's Gemfile. If it did not, deploying your application to production might change all your dependencies, eliminating the benefit of Bundler. You could no longer be sure that your application uses the same gems in production that you used to develop and test with. Additionally, adding a dependency in production might result in an application that is impossible to deploy. Another example: imagine a simple Rack application that has gem 'rack' in the Gemfile. Again, imagine that you put rack-debugging in the :production group.

If we did not evaluate the :production group when you installed via bundle install --without productionyour app would use rack 1. In short, by always evaluating all of the dependencies in your Gemfile, regardless of the dependencies you intend to use in a particular environment, you avoid nasty surprises when switching to a different set of groups in a different environment.

Rails Gem Bundle Install

Q : I have a C extension gem, such as mysqlwhich requires special flags in order to compile and install. How can I pass these flags into the installation process for those gems? A : First of all, this problem does not exist for the mysql2 gem, which is a drop-in replacement for the mysql gem.

In general, modern C extensions properly discover the needed headers. If you really need to pass flags to a C extension, you can use the bundle config command:.

As a result, once you specify the necessary build flags for a gem, you can successfully install that gem as many times as necessary. Q : I do not have an internet connection but I have installed the gem before. How do I get bundler to use my local gem cache and not connect to the gem server? A : Use the --local flag with bundle install. The --local flag tells bundler to use the local gem cache instead of reaching out to the remote gem server. Q : When I bundle from RubyGems.

Is there anything I can do to make it faster?
