Install gems on Windows 7

Hi,
I'm trying to install a gem in a location of my preference. Defaults Rubygems seems determined to install on my user network drive, which I don't want.

I played around with GEM_HOME thinking this might be a way to specifiy a non-default location for my gems. I tried set GEM_HOME=D:/gems and set GEM_HOME=D:/gems/lib/ruby/gems/1.8. This variable does seem to do much. Gem install will always install in my user network drive.

I'm trying to do this on Windows 7 using Ruby 1.8.6 and Rubygems 1.3.7.
Thanks and Regards,
Onno

   Can you paste the output of gem env ?

   I have the same problem with Ruby 1.9.2 and Ruby 1.9.1.

   I have even uninstalled Ruby, removed the network drive, and then installed after with no luck.

   Also, gems keeps giving me an error where they specify there is no space left on the network drive but several gigs of space is available.

   Please, either Jim Bates or Onno, provide the complete output of your gem install command adding --debug -V options to it.

   E.g. If the command was gem install rails then the full command will be gem install rails --debug -V

   Use Pastie.org or gist.github.com to upload the full output and we will be able to help you better.

   Thank you, was hoping you put this in a pastie anyhow.

   H:/ seems to be a network drive.

   Can you confirm the value of the following environment variables?

   SET HOME SET HOMEDRIVE SET HOMEPATH SET USERPROFILE

   Please add the output to this conversation.

   I am getting the same error message.

   Here is my debug text.

   http://pastie.org/2024367

   And here are the values you ask for. In my case, H:/ is definitely a network drive.

   Hello,

   On your second pastie I see you have some errors in the definition of HOMEPATH

   Since HOME is not set, Ruby is trying to use the combination of HOMEDRIVE and HOMEPATH but the value you have in HOMEPATH seems invalid (echo %HOMEPATH% seems completely invalid)

   Please properly set HOMEPATH to the directory of the H: unit assigned to you and try again.

   Ideally, things should look this way:

   C:\Users\Luis\Projects\oss\ruby>set HOME
   HOMEDRIVE=C:
   HOMEPATH=\Users\Luis
   

   Where C: is in HOMEDRIVE and the path is on HOMEPATH.

   Please adjust that and try again.

   Thanks for the response!

   I saw a couple of sites that suggested renaming or deleting the following directory:
   c:\ruby192\lib\ruby\site_ruby

   I renamed it, and reinstalled. Everything worked great.

   Dunno what renaming that directory has nothing to do with gem installation unless your installation wasn't clear. Would love to know were you read that...

   Anyhow, it is clear that your environment variables are not properly set and beyond that directory I forsee issues in the future if these variables are not corrected.

    FYI: It is not uncommon in company environments to map HOME to a network drive (e.g. H: is mapped to \server\home\user). At least on my computer (Windows 7) that network drive is not available from the command line (e.g. I can access H: using Windows explorer, but I cannot user the H drive from the command line).

    In my case I could execute "SET HOME=%USERPROFILE%" and after that it seems to work

    Is this resolved? Confused as to the current status of this issue...can gems be installed properly on win7?

    I have set the gem up on several windows 7 boxes and I have never been
    able to replicate the issue.

    Hi nick.

    I found the post using google, and thought to add my resolution for others. You should not consider my addition as a reopening of an old issue.

    Kind regards
    / Erik

    Hi jim. The issue is resolved for me. If youd like, i could supply my configuration details (mapped network drive in offline mode) and process (railsinstaller) for your knowledgebase?

    That would be great! I have added the support and knowledge base manager
    to the thread.

    Emil, Mark, and Eric. I'll follow up to you with the details behind this
    one.

    Would you mind adding this to the RubyInstaller's Troubleshooting wiki page?

    https://github.com/oneclick/rubyinstaller/wiki/Troubleshooting

    Closing this now since the issue seems to be solved.
