cannot load such file — bundler/setup (LoadError)

问题

I'm setting Rails 4 application with Ruby 2.0, but I'm getting "Web application could not be started" and get this trace:

cannot load such file -- bundler/setup (LoadError)
  /usr/local/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:53:in `require'

  /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19/helper-scripts/rack-preloader.rb:28:in `<main>'

My apache2.conf is:

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19/buildout/apache2/mod_passenger.so
   PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19
   PassengerDefaultRuby /usr/local/bin/ruby

bundle -v is:

Bundler version 1.3.5

ruby -v is:

ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]

gem env is:

echo $GEM_PATH is:

/usr/lib/ruby/gems/1.8:/usr/lib/ruby/gems/1.8

Shouldn't GEM_PATH be /usr/lib/ruby/gems/2.0?

Inside the virtual host in apache2.conf I added:

SetEnv GEM_HOME /usr/lib/ruby/gems/1.8

And now it is working.

Is it the right way to fix this?

回答1:

It could be that there was a previous Ruby env installed on your system prior to your installation of 2.0? This might have had an existing GEM_PATH that lead to the /1.8 directory which the installation of version 2.0 simply kept.

The problem you where likely having, then, was that Passenger/Apache was looking in the /2.0 directory when in fact the gems were in the /1.8 directory. Your explicitly telling apache to use the /1.8 directory thus makes sense to fix the problem.

SetEnv GEM_HOME /usr/lib/ruby/gems/1.8

You might also try using the Ruby Version Manager to handle multiple Ruby envs.

Some things I found in Google:

New to Ruby and am having trouble with LOAD_PATH

http://guides.rubygems.org/faqs/

回答2:

I had almost precisely the same error, and was able to completely fix it simply by running:

gem install bundler

It's possible your bundler installation is corrupt or missing - that's what happened in my case. Note that if the above fails you can try:

sudo gem install bundler

...but generally you can do it without sudo.

回答3:

You most likely have more than one Ruby installed.

If you are using RVM, you probably need to run:

rvm use system

to set the version of ruby to use.

See http://rvm.io/rubies/default

ruby -v

will tell you the version you are currently using.

回答4:

You can try to run:

bundle exec rake rails:update:bin

As @Dinesh mentioned in Rails 5:

rails app:update:bin

回答5:

In my case, the lines appended to the apache config file after installing passenger were as follows:

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-.0.24/buildout/apache2/mod_passenger.so 
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-4.0.24 
PassengerDefaultRuby /usr/bin/ruby1.8

But the app requires Ruby 2.0.0 so it took me a while but finally, the error was resolved after specifying a different path using 'PassengerRuby' below, within the Apache virtual host config file for the app:

...
VirtualHost *:80>
  ServerName www.yourhost.com

 **PassengerRuby /home/user/.rvm/gems/ruby-2.0.0-p247**
  # !!! Be sure to point DocumentRoot to 'public'!
  DocumentRoot /somewhere/public    
  <Directory /somewhere/public>
     # This relaxes Apache security settings.
     AllowOverride all
     # MultiViews must be turned off.
     Options -MultiViews
  </Directory>
</VirtualHost...

回答6:

I got this error in a fresh Rails app with bundle correctly installed. Commenting out the spring gem in Gemfile resolved the problem.

回答7:

I ran into the same issue, but I think it was due to spring caching some gems and configurations. I fixed it by running gem pristine --all.

This restores installed gems to pristine condition from files located in the gem cache.

回答8:

This was happening in the production environment for me.

rm /vendor/bundle

then bundle install --deployment

resolved the issue.

回答9:

Other possible situation: you have multiple users defined in your server environment. In that case, running

passenger-config --ruby-command

will give you the necessary command to specify your nginx/sites-enabled/relevant_application file with your use case, example:

passenger-config was invoked through the following Ruby interpreter:
Command: /home/other_user/.rbenv/versions/2.4.5/bin/ruby
Version: ruby 2.4.5p335 (2018-10-18 revision 65137) [x86_64-linux]
To use in Apache: PassengerRuby /home/other_user/.rbenv/versions/2.4.5/bin/ruby
To use in Nginx : passenger_ruby /home/other_user/.rbenv/versions/2.4.5/bin/ruby
To use with Standalone: /home/other_user/.rbenv/versions/2.4.5/bin/ruby /usr/bin/passenger start

回答10:

i had the same issue and tried all the answers without any luck.

steps i did to reproduce:

rvm instal 2.1.10
rvm gemset create my_gemset
rvm use 2.1.10@my_gemset
bundle install

however bundle install installed Rails, but i still got cannot load such file -- bundler/setup (LoadError)

finally running gem install rails -v 4.2 fixed it

回答11:

I had this because something bad was in my vendor/bundle. Nothing to do with Apache, just in local dev env.

To fix, I deleted vendor\bundle, and also deleted the reference to it in my .bundle/config so it wouldn't get re-used.

Then, I re-bundled (which then installed to GEM_HOME instead of vendor/bundle and the problem went away.

回答12:

NOTE: My hosting company is Site5.com and I have a Managed VPS.

I added env variables for both GEM_HOME and GEM_PATH to the .htaccess file in my public_html directory (an alias to the public directory in the rails app)

They were not needed before so something must have changed on the hosts side. It got this error after touching the restart.txt file to restart the passenger server.

Got GEM_PATH by:

echo $GEM_PATH

Got the GEM_HOME by:

gem env

回答13:

For me the problem was associating RVM Ruby with Passenger. So I needed to integrate RVM ruby wrapper to passenger config file.

I find out rvm ruby wrapper path with command:

passenger-config --ruby-command

I took the path from the result and entered to a passenger config in nginx/passenger.conf:

passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /usr/local/rvm/gems/ruby-2.3.1/wrappers/ruby;

回答14:

Bundler Version maybe cause the issue.

Please install bundler with other version number.

For example,

gem install bundler -v 1.0.10

回答15:

I've fixed that problem by creating test rails project and install all gems then I've replaced my current Gemfile.lock with the test and all thing works fine.

I think that this problem from bundler versions with hosting, so please make sure that hosting bundler is the same version with your project.

回答16:

In my situation it was matter of the permissions:

 sudo chmod -R +777 <your_folder_path>

回答17:

The version of ruby version which phusion passenger was used is differenced with your rails app.

<IfModule mod_passenger.c>
  PassengerRoot /usr/local/rbenv/versions/2.5.3/lib/ruby/gems/2.5.0/gems/passenger-6.0.2
  PassengerDefaultRuby /usr/local/rbenv/versions/2.5.3/bin/ruby
</IfModule>

Make sure the version on httpd config is the same with rails app.
