Rake Error

First time trying to learn Ruby on Rails from the (it would seem now
badly out of date) Linda.com tutorials…

I was trying to rake db:migrate and received this error “/usr/bin/rake:
27:in `require’: no such file to load – rake (LoadError) from /usr/
bin/rake:27”

The tutorial assures me that there shouldn’t be an error and if there
is that I shouldn’t worry as I will only have to solve it once…
thank god I am reassured…

Any insight would be appreciated because I have googled and can find
anything that may be of assistance…

did you install rails via the gem or via apt-get?

Hey mike

Installed via the gem… command was

sudo gem install rails --include-dependencies

returned…

INFO: gem install -y is now default and will be removed
INFO: use --ignore-dependencies to install only the gems you list
Successfully installed rails-2.1.2
1 gem installed

Which was not exactly what I had expected at the time…

I have been poking around and it would seem that rake is not installed
at all… at least it is not in /usr/local/bin…

That’s just telling you that the --include-dependencies option is now
the default option.

Well you have just tried the rails gem, not the rake one. Is rake
included in the list outputted by
gem list
?

Where is gem itself (ie what does which gem say?). In general
executable scripts installed by gem would end up in the same place.

OK I just did a gem install rake to see what would happen and got

/usr/local/bin aren’t both writable.

I should probably say also that I am not using Mac

I use Hardy (Ubuntu 8.04)

OK did a sudo install of rails and rake… they are both in /usr/local/
bin and ALSO in /usr/bin (not sure how that happened)

I still get the same error message… completely confused now…

I’d guess that you’ve ended up with 2 installs of ruby: one in /usr,
and the other in /usr/local. the rake executable from /usr/bin is
trying to load the rake gem from the ruby install in /usr which fails
because you’ve installed the rake gem in your other ruby install (the
one in /usr/local). If that is true then removing rake from /usr/bin
might help - the shell will then find the one in /usr/local. You could
test this out by running /usr/local/bin/rake db:migrate instead of
rake db:migrate

Fred

Thanks for the help guys…

I bit the bullet and trashed everything… then rebuilt the system…
but this time used the repositories and then upgrades where needed…
then made symbolic links to /usr/local/bin from usr/bin and vóila she
works…

Hopefully things will go smoother from now

Cheers
