Ruby 3.2.3 rake似乎不起作用-或其他原因。 耙子流产了！ 无法加载此类文件

Question

So I'm trying to learn Ruby and rails from Lynda.com When I get to the database sections the teacher has us do this schema dump with rake but it aborts and I cant figure out whats wrong (I'm very new to all this so please forgive me =))

OS: Lion
Ruby: ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.3.0]
Rails: Rails 3.2.3
Rake: rake (0.9.2.2)
$PATH: /usr/local/Cellar:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

All the gems should be up to date ( just reinstalled the other day ). If you need to know anything else to help troubleshoot please let me know!

This is the errors I'm getting:

Alex$ rake db:schema:dump
rake aborted!
cannot load such file -- bundler/setup

(See full trace by running task with --trace)

Got this when I tried to reinstall budel and run this command:

The error is to long to fit into this field.

Answer 1

I've resolved this by running:

gem install bundler

If you try that and it shows you have bundler installed, try typing:

bundle exec rake db:schema:dump

You may be running the command outside the scope of the current bundle.

Here's a bit more background information on why you need to add bundle exec in front of your rake commands:

http://gembundler.com/

Also, note that rake isn't required in your 'Gemfile' as long as you have rails specified. rake installs as a dependency of rails . To see the correlation, take a look at your Gemfile.lock .

Once you install rvm, add the following to a file named .rvmrc in the root directory of your project:

if [[ -d "${rvm_path:-$HOME/.rvm}/environments" \
  && -s "${rvm_path:-$HOME/.rvm}/environments/ruby-1.9.3-p125@MYPROJECTNAME" ]] ; then
  \. "${rvm_path:-$HOME/.rvm}/environments/ruby-1.9.3-p125@MYPROJECTNAME"  
else
  rvm --create use  "ruby-1.9.3-p125@MYPROJECTNAME"
fi

Substitute your project name for "MYPROJECTNAME" and the appropriate ruby version where you see ruby-1.9.3-p125 . Then when you change into that directory, rvm will automatically set the gemset and ruby version for you.

Answer 2

Install rvm

Create a new gemset for ur project. Im betting youre using aystem ruby that comes with Lion in some regards

Answer 3

The problem seems to be that I installed bundle after I installed ruby & rails. I uninstalled ruby and all my gems (but left bundle and homebrew) and then used rvm to install the latest ruby and rails.

Also note I did not use sudo unless it required me to. I think this put the files in a different place and that might have also helped.

rake commands are now working (with out using the bundle command before it).

So basically I had bundle installed and then did everything this guy did at the bottom of his questions ( #5 gave me and error and did not install ).

How do you install (build) Ruby 1.9.3 on OSX Lion?

Hope this helps anyone else running into the same problem I did.
