Any ideas as to why the Devise gem will not be installed after properly adding it to the Gemfile and starting the package installation?

I had a server running at one point (rails server) and saw an article stating that trying to install Devise while the server might cause strange problems.

Since then, I tried again with the server, but had no difference. I am sure that this is probably due to something really simple that I forgot in the setup, I just don't know where else to look.

Any tips or suggestions on where to look further would be great, thanks.

I tested using the command below, but still got the same error:

 leigh@leigh-VirtualBox :~/Projects/dev01$ bundle exec rails g devise:install Could not find generator devise:install. 

The list of installed generators is given below, but Devise is not specified, how to get it?

 leigh@leigh-VirtualBox :~/Projects/dev01$ rails generate Usage: rails generate GENERATOR [args] [options] General options: -h, [--help] # Print generator options and usage -p, [--pretend] # Run but do not make any changes -f, [--force] # Overwrite files that already exist -s, [--skip] # Skip files that already exist -q, [--quiet] # Suppress status output Please choose a generator below.

Answer 1

OK, I'm still not 100% sure why this worked or what caused the problem in the first place, but after executing the following commands:

 leigh@leigh-VirtualBox :~/Projects/dev01$ gem uninstall devise Successfully uninstalled devise-3.2.4 leigh@leigh-VirtualBox :~/Projects/dev01$ gem uninstall warden Successfully uninstalled warden-1.2.3 leigh@leigh-VirtualBox :~/Projects/dev01$ bundle install Fetching gem metadata from https://rubygems.org/......... Fetching additional metadata from https://rubygems.org/.. [... text removed ...] Installing warden 1.2.3 Installing devise 3.2.4 [... text removed ...] Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed. leigh@leigh-VirtualBox :~/Projects/dev01$ rails generate devise:install create config/initializers/devise.rb create config/locales/devise.en.yml 

Woo hoo! the problem is solved. A great way to lose a couple of days: - (

Answer 2

same problem today, I removed 'spring' from the Gemfile and it did the trick. or you can disconnect your spring first and run the rails to generate devise: install

Answer 3

What worked for me:

 $ sudo -s $ bundle exec rails generate devise:install 

Without sudo or starting the "initializer" /bin/bash --login did not work. Another solution might be to remove Gemfile.lock and run bundle install again.

Answer 4

This seems to work on my machine under RVM, but with a new gemset. If you are using a version of Ruby (or an RVM gemset) shared with other Rails installations, you may have problems.

As you use the bundler, you should probably use:

 bundle exec rails g devise:install 

as a general precaution to make sure that you are using gems.

Answer 5

I fixed it by adding the following line to my Gemfile :

 gem 'devise' 

After adding this line, I performed bundle install .

Answer 6

I had the same problem today. I tried to remove devise and warden , but no luck. Finally, I uninstalled Gemfile.lock and ran bundle install again, and this did the trick.

Answer 7

This will sound funny, but open a new terminal window and try again. This is what I ended up for me. If this still does not work, try:

DISABLE_SPRING=1 bundle exec rails g devise:install

Answer 8

Restarting the console will fix this problem.
