Gem list and . ~/.profile

Rails
1

Hello,

So, I have something happening that I don’t understand. I am on OS
10.5.6 and followed Dan Benjamin’s (Hivelogic) advice on how to
install Ruby, MySQL… As he suggests, I added . ~/.bash_login with
the path for the MySQL installation. I also added . ~/.profile with
the path for the Ruby installation.

Now, when I start Terminal and run:
% ruby -v # -> version 1.8.6
% gem list # -> I get a list with various versions of active record,
actionmailer, rake and… no mysql (2.7) gem

Then if I run:
% . ~/.profile
% ruby -v # -> version 1.8.7
% gem list # Get updated gem list including mysql gem

But if I close that terminal window and open a new one – the above is
reset.

Why does that happen? and how do I get the path to load automatically?

Thanks,
Elle

Put the settings ~/.bash_profile

Try putting this stuff in a file called .bashrc.

Put the settings ~/.bash_profile

My ~/.profile has:

export PATH=“/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:
$PATH”

And my ~/.bash_profile has the following:

for a in local $(ls /opt/ | grep -v local | grep -v gentoo); do
FULLPATH=/opt/$a
if [ -x $FULLPATH ]; then
if [ -x $FULLPATH/bin ]; then
export PATH=“$FULLPATH/bin:$PATH”
fi
if [ -x $FULLPATH/sbin ]; then
export PATH=“$FULLPATH/sbin:$PATH”
fi
if [ -x $FULLPATH/share/aclocal ]; then
export ACLOCAL_FLAGS=“-I $FULLPATH/share/aclocal
$ACLOCAL_FLAGS”
fi
if [ -x $FULLPATH/man ]; then
export MANPATH=“$FULLPATH/man:$MANPATH”
fi
if [ -x $FULLPATH/share/man ]; then
export MANPATH=“$FULLPATH/share/man:$MANPATH”
fi
if [ -x $FULLPATH/lib/pkgconfig ]; then
export PKG_CONFIG_PATH=“$FULLPATH/lib/pkgconfig/:
$PKG_CONFIG_PATH”
fi
fi
done

Setting PATH for Subversion 1.5.1 binaries

The orginal version is saved in .bash_profile.svnsave

PATH=“/opt/subversion/bin:${PATH}”
export PATH

What rules should I add to it? and where do I add them?

You have an /opt/gentoo directory on Mac OS X? If you’ve got emerge
working, I’d love to know how.

You want either a .profile or a .bash_profile, not both. Once bash sees
the .bash_profile, it won’t look for the .profile; that’s why you’re
having to source it manually. From bash(1):

 When  bash is invoked as an interactive login shell, or as a
 non-inter- active shell with the --login option, it first
 reads and executes  com- mands  from  the file /etc/profile,
 if that file exists.  After reading that file, it looks for
 ~/.bash_profile, ~/.bash_login, and ~/.profile, in  that
 order, and reads and executes commands from the first one
 that exists and is readable.

I actually prefer just to have a .profile, but if you have to support
other sh-derivatives, .bash_profile lets you play it safe.

Thank you for explaining. Just to verify that my path will be set
correctly, I should change:

PATH=“/opt/subversion/bin:${PATH}”
export PATH

to

PATH=“/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/opt/
subversion/bin:${PATH}”
export PATH

is that correct?

No; there was no problem with what you had, just that you split it
across two or three files. You only should have exactly one of
.profile, .bash_profile, and .bash_login.

No /opt/gentoo directory. Only /opt/subversion and /opt/git
Sorry

Sorry to be difficult but I actually have all 3 files.
Which should I delete?
And then, what happens to the information within?

Sorry, reread your post – Just confused with an earlier sentence:

Concatenate them. For example, something like:

cp /dev/null profile
for f in ~/.profile ~/.bash_login ~/.bash_profile
do
mv $f orig$f
cat $f >> profile
done
mv profile ~/.profile

Whoops, you’d have to swap those lines. Warning: I haven’t actually run
this code.

Did not work well.
I changed it to the following:

cp -p ~/.profile ~/.profile.orig
cp -p ~/.bash_login ~/.bash_login.orig
cp -p ~/.bash_profile ~/.bash_profile.orig
cp /dev/null profile
for f in ~/.profile ~/.bash_login ~/.bash_profile; do
cat $f >> profile
mv profile ~/.profile
done

What it did is, it placed .bash_profile content into .profile insetad
of adding it.

Solved.
Both the ~/.profile and ~/.bash_login had the same path defined but
did not load in login.
Adding the path to ~/.bash_profile fixed the problem.
Checked:

which mysql
which svn
which git
gem list

and all is good.

Half way through, I realised it wasn’t really a rails problem – so,
apologies for that.
Hopefully, this will help someone else.

Thanks,
Elle
