“Could not find bundler” error

问题:

When I try to do bundler update I get this error:

.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in
`to_specs': Could not find bundler (>= 0) amongst
[rake-0.8.7, rake-0.8.7, rubygems-update-1.8.4] (Gem::LoadError)

I'm new to Ruby, can someone tell me what would cause this? Rake 0.8.7 is installed.

回答1:

Make sure you're entering "bundle" update, if you have the bundler gem installed.

bundle update

If you don't have bundler installed, do gem install bundler.

回答2:

I had this problem, then I did:

gem install bundle

notice "bundle" not "bundler" solved my problem.

then in your project folder do:

bundle install

and then you can run your project using:

script/rails server

I had the same problem. This worked for me:

1. run rvm/script/rvm and also add it to your .profile or .bash_profile as shown in https://rvm.io/rvm/install/

2. use bundle without sudo

回答4:

If You are using rvm, then try the following command:

rvmsudo gem install bundler

According to another question: Could not find rails (>= 0) amongst [] (Gem::LoadError)

Hope it helped, Cheers

回答5:

The command is bundle update (there is no "r" in the "bundle").

To check if bundler is installed do : gem list bundler or even which bundle and the command will list either the bundler version or the path to it. If nothing is shown, then install bundler by typing gem install bundler.

I had the same problem .. something happened to my bash profile that wasn't setting up the RVM stuff correctly.

Make sure your bash profile has the following line:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"  # This loads RVM into a shell session.

Then I ran "source ~/.bash_profile" and that reloaded everything that was in my bash profile.

That seemed to fix it for me.

回答7:

According to this answer to a similar question, it should be enough:

rvmsudo gem install bundler.

Cheers

回答8:

You may have to do something like "rvm use 1.9.2" first so that you are using the correct ruby and gemset. You can check which ruby you are using by doing "which ruby"

回答9:

I got this after upgrading to ruby 2.1.0. My PATH was set in my login script to include .gem/ruby/2.0.0/bin. Updating the version number fixed it.

回答10:

The system might be running "rootless". Try to set the firmware nvram variable boot-args to "rootless=0". Try to run set of commands:

sudo nvram boot-args="rootless=0"; 
sudo reboot

After reboot completes, run:

sudo gem install bundler

回答11:

Can be related to https://github.com/bundler/bundler-features/issues/34 if you are running the command inside another bundle exec. Try using Bundler.with_original_env if that is the case.

回答12:

For anyone encountering this issue with Capistrano: capistrano isn't able to locate the bundler. The reason might be that you installed bundler under some other gemset where the Capistrano isn't even looking.

1. List your gemsets.

rvm gemset list

2. Use a particular gemset.

rvm use 'my_get_set'

3. Install bundler under that gemset.

gem install bundler

Then, try again with the deploy task.

回答13:

In my case I believe I had an old Ruby remaining on the system, not registered on rvm, and even if the path variables and gem list was okay, it would still use the old Ruby during deployments with Capistrano

And then I realized, the Ruby I had installed with rvm wasn't set to the default one. Running

rvm alias create default <rvm_registered_ruby>

Fixed it.
