I am using gem cells for shopping cart and use following command
rails generate cell cart display -e haml
it generate cells and give error
create app/cells/cart_cell.rb
invoke haml
create app/cells/cart/display.html.haml
error rspec [not found]
i have installed
sudo gem install rspec
but problem not solved. Can anyb'dy help?
Please put following line into your Gemfile
gem "rspec-cells", ">= 0.1.3", :group => [:test]
and run bundle for installing the gem.
Please note, that you have to call
rails generate cell cart display -e haml -t rspec

Hi everyone here is my question:
I have an external project that has to use the MessageDigestPasswordEncoder from Symfony2, here is my code. I dont get it included correctly:
require_once "../htdocs/vendor/autoload.php";
$loader->registerNamespace('Symfony\Component\Security\Core\Encoder\MessageDigestPasswordEncoder', '../htdocs/vendor/symfony/security/Symfony/Component/Security/Core/Encoder/MessageDigestPasswordEncoder.php');
$encoder = new MessageDigestPasswordEncoder();
$password = $encoder -> encodePassword($password, '');
Here is my error message:
Warning: require_once(__DIR__/composer/autoload_real.php) [function.require-once]: failed to open stream: No such file or directory in C:\workspace_aps\gitlist\htdocs\vendor\autoload.php on line 5
Fatal error: require_once() [function.require]: Failed opening required '__DIR__/composer/autoload_real.php' (include_path='.') in C:\workspace_aps\gitlist\htdocs\vendor\autoload.php on line 5
This means vendor libraries are yet to install, or if already installed then you can try to update vendor libraries.
If you need to install all vendor libraries then install curl, composer.
Install curl
sudo apt-get install curl
sudo apt-get install php5-curl (this i executed after getting following exceptions)
Install Composer
curl -sS https://getcomposer.org/installer | php
Run Composer
sudo php composer.phar
This command will show all available options
Install vendor libraries
sudo php composer.phar install
(meaning of this : Installs the project dependencies from the composer.lock file if present, or falls back on the composer.json)
If you already have every thing installed, try to update existing vendor libraries..
sudo php composer.phar update
I'm using Ruby 2.0.0 and Rails 4 but I'm getting an error with coffee-script when I generate new rails project
Installing coffee-script-source (1.6.3)
Errno::EACCES: Permission denied - /usr/local/rvm/gems/ruby-2.0.0-p247/build_info/coffee-script-source-1.6.3.info
An error occurred while installing coffee-script-source (1.6.3), and Bundler cannot continue.
Make sure that gem install coffee-script-source -v '1.6.3' succeeds before bundling.
I just ran into the same problem. Run
sudo bundle update
inside your new site directory. Ruby will then have no trouble installing whatever packages it needs to.
I has the same issue and came across your post when I googled it. I had to run:
sudo gem install turbolinks -v '1.3.0'
sudo gem install uglifier -v '2.2.1'
sudo gem install multi_json -v '1.8.2'
before I could get the bundle install to complete. However, if you are reading the rails tutorial (http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec-rubygems), it says not to worry if that stage fails, as the railsgem file is updated and you manually run:
bundle update
bundle install
Hope this is of some help.
do once: sudo rails new demo
and then for other projects just rails new project_name
I am using whenever gem in my application. And i have scheduled a rake task every 5 minutes. But that rake task is not running every 5 minutes. When i saw the log it gave me error like
`to_specs': Could not find bundler (>= 0) amongst [bigdecimal-1.1.0,
io-console-0.3, json-1.5.4, minitest-2.5.1, rake-0.9.2.2, rdoc-3.9.4]
(Gem::LoadError)
this is the content in schedule.rb
every 3.minutes do
rake "mytask name"
end
I had same issue solved by putting
env :PATH, '/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin'
instead of
env :PATH, ENV['PATH']
on the top of config/schedule.rb
This issue occurs whenever we changes in your gem file, specially rails / ruby version.
I was facing this same issue, here is what I did to get rid of that-
1. $ gem install bundle
2. $ bundle install
Now everything working fine.
If you are getting same issue as-
`to_specs': Could not find 'railties' (>= 0) among 23 total gem(s) (Gem::LoadError)
then here are the steps-
See the link as-
Rails: Could not find railties
1. $ gem list
2. $ gem install rails
It will just download all missing dependencies, including railties.
Hope this will work for you too !!!
XML::Parser fails to build on a quite fresh 64-bit Debian box. After issuing cpan XML::Parser, cpan fails with lots of errors about Expat.c and Expat.xs:
[...]

Running make test

Running make install
Make had returned bad status, install seems impossible
Message at the start of the output explains that expat-devel is needed for building.
Expat must be installed prior to building XML::Parser and I can't find
it in the standard library directories. Install 'expat-devel' package with your
OS package manager. See 'README'.
But expat-devel is not in Debian repository.
Is it possible to get over this without need to build/install expat from source?
The package you want to install is named libexpat1-dev. You could also just install libxml-parser-perl via apt-get. Or if you really want to install via CPAN try installing the Debian packages dependencies first via apt-get build-dep libxml-parser-perl.
libexpat1-dev contains both libexpat and expat.h, which are both mentioned in the message as well:
If expat is installed, but in a non-standard directory, then use the
following options to Makefile.PL:
EXPATLIBPATH=... To set the directory in which to find libexpat
EXPATINCPATH=... To set the directory in which to find expat.h
Installing libexpat1-dev seems to solve the problem:
$ aptitude install libexpat1-dev
There is always the manual method - to build/install expat from source.
(This example shows installing to an alternative location for XAMPP | LAMPP)
Download from:
http://sourceforge.net/projects/expat/files/expat/
tar zxf /[where-ever]/expat-2.1.0.tar.gz -C /tmp

Work like a charm in Ubuntu 15.04. The only thing that I need is install Perl XML Parser with:
sudo apt-get install libxml-parser-perl
And following the instructions here, I was able to import successfully all my ratings into Rhythmbox. Now, the only work that I need to do is create again the smart play lists, that is nothing compared with my entire libray ratings.
Today I had the same issue wanting to complile the new GIMP 2.9.4 beta on OSX 10.8 and the aid of homebrew.
First install perl
brew install perl
Then the XML::Parser module by going into the perl shell with
perl -MCPAN -e shell
And inside the shell install XML::Parser by typing
install XML::Parser
Exit shell
exit
Now, verify it has been installed successfully. If everything is ok, you will not see an error.
perl -e "require XML::Parser"
If the ./configure still fails missing XML::Parser, then intltools is not using the perl you have installed. Looking at the script tells me it does the test with $INTLTOOL_PERL -e "require XML::Parser". Trying a echo $INTLTOOL_PERL gave out nothing, so the magic is to set it with
export $INTLTOOL_PERL=perl
Now run ./configure again.
None of the above methods worked for me. I had the right environment variables setup but they were somehow not picked up by cpanm that I use to install perl modules. Expat was also installed.
Here is what I did to overcome the same problem that OP is reporting.
This is very close to what #LadyBuzz suggested.
Download the XML::Parser from cpan.org
Extract the tarball into directory and descend to it.
Open the Makefile.pl and edit the first lines to actually have the absolute paths to both: EXPATLIBPATH and EXPATINCPATH
Save the Makefile.pl, go up one level and create a new tarball with the Makefile.pl that you just edited.
Execute cpanm on the newly created tarball.
This resulted in successful installation of the module.
I just upgraded to Rails 3.1 and the first app i've tried to deploy to Heroku has encountered a problem relating to Postgres adapter. I'm able to push the app to heroku but then when i try to migrate the database i get the following error:
heroku rake db:migrate
rake aborted!
Please install the postgresql adapter: `gem install activerecord-postgresql-adapter`
(pg is not part of the bundle. Add it to Gemfile.)
Tasks: TOP => db:migrate => db:load_config
(See full trace by running task with --trace)
when I try their suggested install i get:
ERROR: Could not find a valid gem 'activerecord-postgresql-adapter' (>= 0) in any repository
ERROR: Possible alternatives: activerecord-postgis-adapter, activerecord-jdbcpostgresql-adapter, activerecord-postgresql-cursors, activerecord-jdbcmysql-adapter, activerecord-jdbcmssql-adapter
which already seems weird... so what exact gem should I install to get this thing working if not what they say I should install??
When I try installing gem pg i get:
Building native extensions. This could take a while...
ERROR: Error installing pg:

I'm using SQLite3 currently. Any help greatly appreciated, this is baffling me.
Option 1:
Add pg to your Gemfile but skip trying to install it locally.
$ cat Gemfile
...
group :production do
# gems specifically for Heroku go here
gem "pg"
end
# Skip attempting to install the pg gem
$ bundle install --without production
Option 2 (Debian/Ubuntu):
Add pg to your Gemfile but first install the prerequisites.
$ cat Gemfile
...
group :production do
# gems specifically for Heroku go here
gem "pg"
end
# Install the pg gem's dependencies first
$ sudo apt-get install libpq-dev
# Then install the pg gem along with all the other gems
$ bundle install
You definitely need pg in the Gemfile for Heroku.
About the error you're getting locally: make sure you have postgres installed, run gem install pq -- --with-pg-config=[path to wherever your pg-config binary is], then bundle install.
Alternatively, if your local database is working fine (either because you're using sqlite or postgres-pr), you could put the gem 'pg' line in your Gemfile in a group called production, then bundle install --without production locally.
More up-to-date info: It had something to do with a different version of pg gem locally.
I already had pg in a production group (I run sqllite locally), but Heroku was still puking.
The problem went away for my new Rails 3.1 app when I:
rm Gemfile.lock
touch Gemfile
bundle install
git add .
git commit -am "wiped Gemfile.lock re-ran bundle install"
git push heroku master
worked like a charm when I then ran heroku run rake db:migrate
