Cannot install Rails with Gems on WIndows

I am using Windows Server 2007 SP2
When I try to install Rails using Gems, it gives me the following error
in the DOS console:


C:>gem install rails
ERROR: While executing gem … (Errno::EACCES)
Permission denied - C:/Program Files/Ruby19/bin/rake.bat

C:>

Then, starting the DOS console as an administrator and retyping the
command gives the following result:


C:>gem install rails
ERROR: While executing gem … (Errno::ENOENT)
No such file or directory - P:/

Can anyone help on this ?

Try running the command prompt as administrator

Hi Sharagoz,

Please see the second part of my message above. That’s exactly what I
did, but there’s still an error.

Do you mean that you’re running it under an administrator account, or
are you right-clicking on the cmd icon and chosing “run as
administrator”?
You need to do the latter, being an administrator is not enough.

I definatly should have read your opening post more carefully. I see
that there’s a difference between the error message in normal and
elevated mode now, which is weird.

I would start by uninstalling Ruby and then reinstalling it into a
directory without a space in the filename (like C:\ruby), then try to
install rails using the same account as I installed ruby with, from an
elevated command prompt.

If that makes no difference, see if you have the same problem with Ruby
v1.8.6

I am both administrator on the system
and doing “Run as administrator” to launch the DOS console.

1.8.7 for windoze is available here:

Is there a difference between the versions on that page and those on
RubyForge ?

I did that already, to reinstall Ruby directly on the C:, and tried
again: gave me the same errors.

I will try to install v1.8.6 or v1.8.7, as now I have 1.9.1p243.

I tried with 1.8.7 (see image) and 1.8.6, and I get the same error.

The only thing I can think of is that something might be up with an
environment variable somewhere. If you run “set >> c:\dump.txt” from the
command line it will export the variables into that file. Post the
result here if you want us to have a look.

So what’s that P: drive supposed to be?

P: is a network drive, but it was nowhere specified at initial
installation of Ruby or when I tried to run Gem, so I don’t know where
it gets it.

HOMEDRIVE=P:
Your problem is probably there.
Run “set HOMEDRIVE=C:”
To verify that it has been set correctly run “echo %HOMEDRIVE%”, which
should now print out “C:”. Try to install rails.

If that enables you to install gems you may want to edit the value
permanently to avoid future problems. The homedrive key is located here:
HKEY_CURRENT_USER\Volatile Environment

IT WORKS! See below.

Many thanks Sharagoz.

for followers, upgrading to a newer version of rubygems (which required
1.8.7) fixed it for me.
