Currently i have blog site which works with Octopress in relationship with Git but currently facing a problm that i can't update the site automatically via a cron triggered script. I'm using a script (update.sh) with the following contents:
#!/bin/bash -x
export PATH=/usr/local/rvm/gems/ruby-2.0.0-p247#global/bin/:/usr/local/rvm/bin/rvm:$PATH
cd /usr/local/repositories
cd supose.git
git fetch -q --all
cd /usr/local/vhost/octopress
git pull
rake generate
/usr/local/rvm/gems/ruby-2.0.0-p247/bin/jekyll generate
But i alway get the following error message:
+ rake generate
## Generating Site with Jekyll
+ /usr/local/rvm/gems/ruby-2.0.0-p247/bin/jekyll generate
invalid command. Use --help for more information
I know there must be a relationship with the environment, but i can't get the point to get it running.
If i login into the machine and cd into the folder and do rake generat it works like a charm.
Check the PATH you have when you login against the one crontab gives you. It may be quite different. rvm does other things as well as set the path. You'll need to make sure our PATH is correct, and run the script that rvm puts in your login profile [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm". You could try running . ~/.bash_profile ; (path_to_script)/update.sh as the crontab command.
instead of changing PATH use a wrapper - this will provide environment for your ruby:
rvm wrapper ruby-2.0.0-p247 --no-links rake jekyll
and then use it like this:
/usr/local/rvm/wrappers/ruby-2.0.0-p247/rake generate
/usr/local/rvm/wrappers/ruby-2.0.0-p247/jekyll generate

I'm trying to implement a git hook that edits some JSON every time I push.
I have JQ installed on my Mac using homebrew "brew install jq", but when the git hook runs my .sh I get the error
jq: command not found
My latest attempts have been to use curl to download the jq library, point to it, and run jq that way:
jq=/usr/local/Cellar/jqz
curl -L -o $jq https://github.com/stedolan/jq/releases/latest/download/jq-osx-amd64
Unfortunately, this is also returning the same 'command not found' error.
Sidenote: jq=/usr/bin/jq gives me a permission error when I try to write to it
jq=/usr/local/Cellar/jqz
curl -L -o $jq https://github.com/stedolan/jq/releases/latest/download/jq-osx-amd64
It looks like you are storing the binary with the name jqz. No surprise that it cannot be executed as jq; you would have to invoke it as jqz.
I don't know if /usr/local/Cellar is part of your PATH?
The canonical way would be:
jq='/usr/local/bin/jq'
curl -L -o "$jq" https://github.com/stedolan/jq/releases/latest/download/jq-osx-amd64
you could also store it in the bin directory of your home folder: `jq="$HOME/bin" which should be added automatically to your PATH on most installations (might require a logout & login).
I am working on a bash server setup script for ubuntu 14.03 LTS. For some of the commands the script is executing, it prompts the user to input 'yes/no' or 'Y/N'. For some of these commands I have been able to pass a flag to the command in question that will auto respond with a yes. For example: sudo apt-get install -y gcc doesn't prompt the user.
On the other hand, I can't seem to find a way to do this for
sudo gem source -a http://rubygems.org/.
It keeps prompting me with Do you want to add this insecure source? [yn].
So far I've tried the following:
yes | gem source -a http://rubygems.org/ which I found here
Any Suggestions?
First add this certificate via script in this folder: {rubyfolder}\lib\ruby\2.1.0\rubygems\ssl_certs
This is a snippet from a Jenkins job run that needs rvm 1.9.3.. I have no idea why the PATH is not being looked at. From this build the PATH environment variable looks correctly set as PATH="/usr/java/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" (as set in /etc/environment), HOME="/scratch" and SHELL="/bin/sh", so I'm mystified by this.
$ bash -c " source ~/.rvm/scripts/rvm && rvm use --install --create ruby-1.9.3 && export > rvm.env"
/scratch/.rvm/scripts/rvm: line 12: uname: command not found
/scratch/.rvm/scripts/rvm: line 15: ps: command not found
bash: rvm: command not found
I have also attempted the rbenv route but am met with similar errors indicating the absence of $PATH
Also, the Jenkins user belongs to the rvm group.
I send many internets in thanks for any assistance offered!
rvm needs login shell.
I use it like this in my builds:
echo "rvm install 2.2.3" | /bin/bash -l
Works just fine this way.
My ruby is in /usr/local/bin. whenever can't find it, and setting PATH at the top of my cron file doesn't work either, I think because whenever is running the command inside of a new bash instance.
# this does not work
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/sbin
# Begin Whenever generated tasks for: foo
0 * * * * /bin/bash -l -c 'cd /srv/foo/releases/20110429110637 && script/rails runner -e production '\''ActiveRecord::SessionStore::Session.destroy_recent(15)'\'''
# End Whenever generated tasks for: foo
How can I tell whenever where my ruby binary is? Making a symbolic link from /usr/bin seems messy to me, but I guess that might be the only option.
This question offers env :PATH, "..." in schedule.rb as a solution, but (a) I can't find any documentation of that feature anywhere in the docs (b) it doesn't seem to have solved the asker's problem (unfortunately it takes non-trivial turnaround time for me to just try it).
update actually it is in the bottom of this page, i'll try it now.
more info
I can't modify the cron command because it's generated by whenever
i verified that if I make a new bash shell with bash -l, /usr/bin/env finds ruby just fine
I just tried the exact command in cron, starting with /bin/bash, from the command line of that user, and it worked.
so, this is very mysterious...
The solution is to put this in schedule.rb:
env :PATH, ENV['PATH']
Here's a little guide I put together on the topic.
rewrite your crontab as
0 * * * * { PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/sbin ; export PATH ;/bin/bash -l -c 'cd /srv/foo/releases/20110429110637 && script/rails runner -e production '\''ActiveRecord::SessionStore::Session.destroy_recent(15)'\''' ; }
Or you should try to figure out why your BASH shell is not picking the PATH=... that is almost certainly in your .profile or .bash_profile.
I hope this helps.
As John Bachir pointed out, you can do it via env. But let me add more input. I am deploying on AWS Opsworks. Unfortunately they do not have a ruby manager (RVM, Rbenv, etc) installed by default.
The first thing I needed to do was SSH into the instance and figure out which ruby I was using. This was easy enough by executing the which ruby command in a terminal.
$ which ruby
/usr/local/bin/ruby
Cron was using ruby located at /usr/bin/ruby. This needed to be changed.
In schedule.rb, I have:
set :env_path, ''
env :PATH, #env_path if #env_path.present?
In local, env_path doesn't need to be set. For most users, the only thing to do is execute whenever as such:
bundle exec whenever --set 'environment=development' --update-crontab
On a staging / production environment, ruby may be installed elsewhere. So running this may be more appropriate:
bundle exec whenever --set 'environment=staging&env_path=/usr/bin/local' --update-crontab
You will need to replace /usr/bin/local with the output of echo $PATH.
In Opsworks, however, I needed to create a custom Chef recipe that looked like:
node[:deploy].each do |application, deploy|
execute 'whenever' do
user 'deploy'
group 'nginx'
cwd "#{deploy[:deploy_to]}/current"
command "bundle exec whenever --set 'environment=#{deploy[:environment_variables][:RAILS_ENV]}&env_path=#{ENV['PATH']}' --update-crontab"
end
end
I hope the information here is clear enough.
I have executed the commands as prescribed in the instructions at the rvm website but things don't seem to work..
Fetching the code from the git repository runs smoothly but when I try to use
rvm notes
Error:
/usr/local/bin/rvm: line 73: /home/cody/.rvm/scripts/rvm: No such file or directory
flashes in multiple lines and doesn't stop till I hit ctrl+C..
I am running Ubuntu 8.04 and currently I am running ruby 1.9.2..
Sorry, if I am missing out any necessary information. Thanks in advance.
Ack, I didn't mean to post this as a comment on the question. Anyway, if I had to guess, I'd say you installed rvm using sudo or as root. If that is the case, remove it and reinstall without sudo:
sudo rm -rf $HOME/.rvm $HOME/.rvmrc /etc/rvmrc /etc/profile.d/rvm.sh \
/usr/local/rvm /usr/local/bin/rvm
sudo /usr/sbin/groupdel rvm # this might fail, it's not that important
Open new terminal window/tab and make sure rvm is removed:
env | grep rvm
The output should be empty, sometimes it's needed to relogin, after it's empty you can continue:
curl -sSL https://get.rvm.io | bash -s stable
It works perfectly fine installed for the local user.
Ok, for anyone who tried to install RVM using sudo and is now pulling
their hair out trying to get it to install in $HOME/.rvm, here's what
did it for me:
When you installed RVM using sudo, it created a file /etc/rvmrc, which contains the following:
umask g+w
export rvm_path="/usr/local/rvm"
This makes all future attempts at installation (even when not run as sudo)
install into /usr/local/rvm, which is NOT what you want for a single
user installation. So remove /etc/rvmrc and then you can run
bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
and it will install properly into $HOME/.rvm
DId you add this line to your ~/.bashrc?
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
I have executed the commands as prescribed in the instructions at the rvm website.
WHICH commands? There are several pages containing instructions to install RVM depending on whether you want a single-user "sandbox" or are installing system-wide for a multi-user system as the administrator.
Because you have RVM in /usr/local, I think you tried to do a system-wide install but didn't get it right. For 99% of us, that is the wrong installation method, and instead you should use the single-user installation, which is simple and puts everything in ~/.rvm.
Either way, be sure to read the entire instructions. And, if doing a single-user install, finish the install with the "Post Install" modifications to ~/.bashrc or ~/.bash_profile for a single-user, then start a new terminal session.
When using the single-user install NEVER use sudo to install gems to a RVM-managed Ruby, even though the instructions for a gem might say to.
Look at the section "Troubleshooting your install" here. Since you are on Ubuntu, you probably need to make further mods to you .bashrc
in .bashrc have you changed the
[ -z "$PS1" ] && return
to
if [[ -n "$PS1" ]]; then
and added this to the end of the file:
fi
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
I just had a similar problem.
It turned out that many files in ~/.rvm/scripts/ and ~/.rvm/src/rvm/scripts/ which obviously should be executable did not have execute permissions. Running a script on both directories to set all files to executable solved that immediate problem.
I have got same problem after installation. Then I restarted terminal and it started working poperly.
