I am getting the following error when doing bundle install
Make sure that `gem install couchbase -v '1.3.3'` succeeds before bundling.
Now, i have not included this gem in the Gemfile
, so it's coming from some dependency. How can i figure out which gem is dependent on this couchbase gem?
Since bundle install
is failing and I don't have Gemfile.lock
to figure out this dependency.
You can always check the reverse dependencies of a gem on rubygems.org. There's a link on the right side panel on the website.
The Gemfile is where you specify which gems you want to use, and lets you specify which versions. The Gemfile. lock file is where Bundler records the exact versions that were installed. This way, when the same library/project is loaded on another machine, running bundle install will look at the Gemfile.
Common Attempts To Resolve Ruby Gem Dependencies Bundler can help to resolve dependencies when working with Ruby gems by allowing you to specify a set of gems in a Gemfile, then issue a single command to install them. Bundler then automatically resolves the dependencies for you.
gem dependency
(with no args) should show you all gems from current Gemfile with their dependencies.
Edit:
You can also do gem dependency -R
(or just dep
instead of dependency
) if you want to find out which gems use specific (or all) gems.
For deeper dependencies I'd parse output (regex maybe?) of first gem dependencies, pick gem's names and call gem dep
on each of them, but that's just a loose idea.
You can also use bundler to create a dependency graph.
Install graphviz:
gem install ruby-graphviz
and then:
bundle viz
Here are an example of a newly created Rails app:
You can also play with the options:
bundle help viz
