Hi,  
I just installed Ruby Enterprise Edition/Passenger on my new VPS but I  
can’t run any rake tasks (I get -bash rake: command not found).

/opt/ruby-enterprise-1.8.7-2010.01/bin/gem list

Successfully lists the installed gems (including rake)

I’ve been told this is because the path is not correctly setup, however  
I can’t seem to get it working correctly.

Can anyone tell me the correct method to make REE the default  
interpreter?

I’m using CentOS 5.

Any advice appreciated.

Thanks.

1. Find where rake is installed

updatedb  
locate rake

1. Prepend the path to rake into your existing PATH.

export PATH=“/path/to/rake:$PATH”

1. Make the new PATH addition permanent by adding the export command  
above into your shell’s rc file, ~/.bashrc or ~/.bash\_profile or  
~/.profile.

You might want to look into using the Ruby Version Manager (RVM) for  
managing  
multiple Ruby VM installs. You can find more information here:

Good luck,

Hi,

I’ve tried doing what you said. Is this correct?

export PATH="/opt/ruby-enterprise-1.8.7-2010.01/bin:$PATH"

I tried putting it in the following file, but it didn’t seem to make any  
difference. Does it have to be placed in a specific location?

Thanks.

# /etc/profile

# System wide environment and startup programs, for login setup

# Functions and aliases go in /etc/bashrc

pathmunge () {  
if ! echo $PATH | /bin/egrep -q “(^|:)$1($|:)” ; then  
if [“$2” = “after”] ; then  
PATH=$PATH:$1  
else  
PATH=$1:$PATH  
fi  
fi  
}

# ksh workaround

if [-z “$EUID” -a -x /usr/bin/id]; then  
EUID=`id -u`  
UID=`id -ru`  
fi

# Path manipulation

if [“$EUID” = “0”]; then  
pathmunge /sbin  
pathmunge /usr/sbin  
pathmunge /usr/local/sbin  
fi

# No core files by default

ulimit -S -c 0 \> /dev/null 2\>&1

if [-x /usr/bin/id]; then  
USER="`id -un`"  
LOGNAME=$USER  
MAIL="/var/spool/mail/$USER"  
fi

HOSTNAME=`/bin/hostname`  
HISTSIZE=1000

if [-z “$INPUTRC” -a ! -f “$HOME/.inputrc”]; then  
INPUTRC=/etc/inputrc  
fi

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC

for i in /etc/profile.d/\*.sh ; do  
if [-r “$i”]; then  
. $i  
fi  
done

unset i
