Gem install - will not work outside of bin folder

Ruby
1

Hi

I just installed ruby 1.8.6 stable version on windows xp pc. When I try
to install gems by gem install gemname…it says ‘command not
recognized’. When I download a gem manually and put in the bin folder
and then use gem install it will work. However, it is only working for
some gems. Other error messages that I am getting is that the gem is of
invalid format. Do you know why I can’t run update gems outside of the
bin folder or why some will not install?

Thanks
MC

Make sure that the “ruby\bin” directory is in your PATH.

I copied those to the bin and then set my path to ruby\bin. Then I use
gem install gemname but it says my rake is of invalid format…so I go
to next gem and use gem install and it says that gem is also of invalid
format.

Thanks Luis… so, you are saying that I can use a commands such as ‘set
Path’ and ‘gem env’? I didn’t know these were available. Where can I
find documentation on using these commands and commands like these?

Will be much more helpful than your description that you can provide
output of:

set PATH
gem env
gem install rake

The actual commands and the real output can help us help you.

set PATH is abuilt-in command of Windows.

set let you set or unset environment variables. PATH is the
environment variable that let the system search for executables.

“gem” is the RubyGems executable you use to install, uninstall and
update gems in your Ruby installation:

http://docs.rubygems.org/

From the command prompt and inside your Ruby\bin directory, execute
the above mentioned commands and check the output.

If you’re not familiar with the command prompt. I suggest you read
more documentation how to use it. Similar knowledge acquired here will
help you on other platforms.
