Gem files will remain installed in /home/bitnami/.bundler/tmp/3622/gems/sqlite3-1.3.8 for inspection.
Results logged to /home/bitnami/.bundler/tmp/3622/gems/sqlite3-1.3.8/ext/sqlite3/gem_make.out
An error occurred while installing sqlite3 (1.3.8), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.8'` succeeds before bundling.

Of course it fails with a permission denied because those gems are in directories managed by root and as the developer I create files and do my stuff as the regular bitnami user, of course. That includes using the rails program and using said program through an IDE. These assumptions seem clearly at odds with how the rubystack is set up or supposed to be used.

Questions :
-If my methods differ from the methods assumed by the stack, then what IS the assumed method?
-If they dont differ, why is making a new project doing administration stuff?
-How should I go about making this thing work at all?

Answer 1

Please make sure the:

ls -l /opt/bitnami/ruby/lib/ruby/site_ruby/2.1.0/x86_64-linux/

say that the folder belongs to you, not to root:root . If the rights are for root user, you can't create the folder, so to fix it just do:

sudo chown bitnami:bitnami /home/bitnami/. -R

I strongly advice you to use rvm and gemset in order to not using the root operations. Do as follows:

1. In order to use the system ruby with rvm just pickup it by execution:

    rvm mount /path/to/system/ruby 

2. Then create a gemset:

    rvm gemset create bitnami 

3. And use it:

    rvm gemset use bitnami 

4. Update or install all gems into the specified gemset, but don't use sudo for the action, just:

    bundle install
