bundle install not running from my post-update hoo

问题:

I've setup a post-update hook for my project. I have a bare repository (/var/git/myproject) which I push to, and a live repository (/var/www/myproject) where my app is running. I also included bundle install and bundle exec rake db:migrate to install gems and update db.

Below is my post-update hook

#!/bin/bash

echo "Pulling changes into Live..."
cd /var/www/myproject || exit
unset GIT_DIR
git pull origin master

# check if ruby app
if [ -f /var/www/myproject/Gemfile ];
then
  echo "  Ruby app detected..."
  bundle install --without development test
  bundle exec rake db:migrate # migrate database
fi

exec git-update-server-info

When I push my changes though I get the following message (notice the "bundle command not found" error):

martyn@localhost:~/www/myproject$ git push -u origin master

Why is bundle not running? I cd to the live app directory in the script. When I'm in terminal myself and I cd to the live directory and run bundle install it works so bundle is there.

回答1:

Your hook shell ins't the same than the one you logged in (and which has the proper PATH)

You can try using at the beginning your your hook script:

#!/bin/bash -l

(See this answer

The -l parameter executes the command in a login shell, which means that it inherits your path and other settings from your shell profile.

)

Or you can make sure your script gets the same environment than your current session, by adding in the first lines of your hook:

$ source $HOME/.bash_profile # single user RVM setup
$ source /etc/profile        # multi user RVM setup

Or (final alternative) you can add (before calling bundle) (for a single-user rvm installation)

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
