Hi,

I've been doing some gem development, but am running into an issue when testing out my gem in an application. The build process seems to work fine, generating the .gem file but when I try to install the gem, it does not appear in my local gem list.

i.e.:

$ sudo gem install ./pixcaptcha-1.0.gem
Password:
Successfully installed pixcaptcha-1.0

$ gem list p

*** LOCAL GEMS ***

passenger (3.0.8, 3.0.7)
Platform (0.4.0)
plucky (0.3.8)
polyglot (0.3.3, 0.3.2, 0.3.1)
pyu-ruby-sasl (0.0.3.3)

Even trying to install something like jeweler says that it was successfully installed, but it does not appear in my local gem list. Should I expect gem install to install them to my local list? Am I missing a step?

    Are you using rvm? Is "gem" between your user and sudo the same? What does
    sudo gem list p result? What is your gemspec?

    Hi,

    Sorry for the late reply.

    I think you're on to something, when I do sudo gem list p, my pixcaptcha does come up. Perhaps my application could not see the gem because I installed it using sudo and not simply gem install ./pixcaptcha-1.0.gem?

    $ sudo gem list p
    Password:
    
    *** LOCAL GEMS ***
    
    passenger (3.0.9, 3.0.7)
    pixcaptcha (1.0)
    Platform (0.4.0)
    plucky (0.4.4, 0.3.8)
    polyglot (0.3.3, 0.3.2, 0.3.1)
    pyu-ruby-sasl (0.0.3.3)`
    

    I have been using sudo gem install because of permissions (to the ruby directory. I think it is a system wide install.

    I am using rvm 1.7.2, and I will attach the pixcaptcha gemspec to the post. I was working on getting jeweler installed, so I may have made some goofs in the gemspec while manually editing (I do realize the file says "DO NOT EDIT THIS FILE DIRECTLY" :) )

    should I grant myself access to write to the ~/.rvm/gems/ruby-1.9.2-p290 directory to install my gem for my application to use?

    Let me know if there is any other information I can provide to help out.

    Most likely your sudo environment is not identical to your non-sudo environment due to sudo environment scrubbing.

    Please compare gem env with sudo gem env and then consult your sudoers file to see which environment variables are not being allowed into the sudo environment. Likely GEM_HOME and GEM_PATH are not allowed.
