Can't run ruby commands from windows command prompt

B

Brad Winborg

I have installed ruby186-27_rc2.exe on windows XP. I have installed it
as user with admin permissions, and as the administrator. I uninstalled
it program completely removing all entries from registry. removing ruby
directory and making sure that all entries are removed from environment.
I have tried this several times, Each time I install it it appears to
install correctly, it is in the environment path but I continue to get
the following error "ruby is not recognized as an internal or external
command operable program or batch file.

This message:

"ruby is not recognized as an internal or external command operable
program or batch file."

Means ruby is not in your PATH.

If you installed Ruby as administrator, it should have modified your
PATH. For the change take effect you will need to logout and login
again to be able to use the command prompt.

Also, ensure that PATH contains the bin folder where ruby was
installed (by default C:\Ruby\bin)

So:

C:\>set PATH

Should display the current path. Look for Ruby\bin in it.

If not, you will need to add manually from the system properties:

Start -> Settings -> Control Panel. Double click on System. Go to
Advanced tab, and then Environment variables option.

From there append the Ruby path to the end of the PATH system
variable.

After it, hit Ok and logout.

HTH,

I did exactly what you said to do. I had already done this several times
but I wanted to be sure. But like before I am still receive the same
error. The bin directory, is in the ruby directory and that is how it
shows in the path. I am not sure why it displays the C:\ruby\bin in that
location of the path, because I did append it to the end.

I don't think you really wanted to remove .exe from the PATHEXT
variable. It seems something has gone wrong when changing that
variable.

PATHEXT could look like this (win xp):
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.RB;.RBW;.py;.pyw;.tcl

Or you would have to run ruby as ruby.exe. I'm not sure if this is
related to your problem though.

Leo thank you that solved the problem, I can't believe I gig not notice
that. I guess sometime you can't see the tree for the forest. Regardless
excellent job.
