Whenever gem 'failed to load command: rake'

Question

looking for some help.

I am running a rails app (v3.2.5) with the whenever gem (v0.9.7) and rake (v11.2.2). I am also doing this in a docker container image ruby:2.3 (cron was installed and bundle install was ran)

Here is my schedule.rb

set :environment, ENV['RAILS_ENV']

every '*/2 9,10,11,12,13,14,15,16 * * 1-5' do
    rake "import_csv", output: {:error => 'log/import_csv_errors.log', :standard => 'log/import_csv.log'}'
end

note RAILS_ENV is set at container launch to development

Here is my cron job that is on the container after build (crontab -l):

# Begin Whenever generated tasks for: /usr/src/app/config/schedule.rb
*/2 9,10,11,12,13,14,15,16 * * 1-5 /bin/bash -l -c 'cd /usr/src/app && RAILS_ENV=development bundle exec rake import_csv --silent >> log/import_csv.log 2>> log/import_csv_errors.log'

# End Whenever generated tasks for: /usr/src/app/config/schedule.rb

When this cron job runs, the logs return:

import_csv_errors.log

import_csv.log

bundler: failed to load command: rake (/usr/local/bin/rake)

Now here is the odd thing. If I copy the cron job command:

/bin/bash -l -c 'cd /usr/src/app && RAILS_ENV=development bundle exec rake import_csv --silent >> log/import_csv.log 2>> log/import_csv_errors.log'

and run this in the container, it works fine, but if the cron job runs it, I get thos errors in the logs!!! I am at a lost here...

I've tried adding

env :PATH, ENV['PATH']
env :GEM_PATH, '/usr/local/bundle'

to the top of schedule.rb and I tried doing

command 'cd /usr/src/app && RAILS_ENV=development bundle exec rake import_csv --silent >> log/import_csv.log 2>> log/import_csv_errors.log'

Instead of using rake in the task and I get the same errors..

Any help is appriciated

Answer 1

I've fixed same error by modifying Dockerfile with:

RUN gem update --system 2.6.12
RUN gem install bundler --version 1.14.6

And schedue.rb:

ENV.each { |k, v| env(k, v) }

Answer 2

I have updated my rake version and it worked for me. Below are the steps I followed:

sudo bundle update rake
sudo bundle install

Open a Rakefile and replace the line rake/rdoctask with require 'rdoc/task'.
