Ruby on Vista

Question

Yesterday I installed Ruby and Ruby on Rails on Vista 32bit using the directions on this site: http://rubyonrails.org/down

so I downloaded the installer, then Gems, then downloaded the rails with Gems.

now I can’t use the Gem or Ruby commands on the command line ... so I assume that something is wrong with the environment variables, but I suggest how to configure them in Vista or what to put. Can anyone help me with this?

Answer 1

To set environment variables do this

• Launch the start menu
• Right click on Computer and select Properties
• Click Advanced system settings in the left pane and confirm the UAC prompt
• Select the Advanced tab (it's third)
• Click Environment Variables... (bottom)
• At the top of the window ( User variables for XXX ), either find the entry for PATH , or click "Create" to create the entry.
  If PATH already exists, use half-columns to separate each directory specified in it.
• Put c:\ruby\bin (change if you installed ruby ​​in another place).
• Click "OK" many times to close all the windows that we opened.
• Restart the command line.

gem and ruby and irb should now work. Who said GUI tools are slower than command line tools. pah!

Answer 2

At the command prompt, type "PATH" and then press return, do you see ruby.exe in the PATH environment variable?

If you installed ruby ​​to say 'c: \ ruby', then it will be 'c: \ ruby ​​\ bin \'.

It seems that the path may be absent.

Answer 3

Add your ruby ​​bin directory to the PATH environment variable, go to Control Panel → System → Advanced system settings, then go to the Advanced tab, Environment Variables, then edit the PATH variable and add the path to the ruby ​​install binaries ; C: \ ruby ​​\ bin
