Webistrano bundler install

And the last, but not least, before we start the build. Webistrano creates all the stylesheets on the first run, so the public folder has to have writeable permissions:.

You will have to install an older version of the bundler. You will have to run bundle install again. All seemed ok, and logging the id of my user running Webistrano was pointing to the correct one, but it seems that there was some sort of conflict and the process was actually running as nobody. You can find more about the issue on stack overflow. If this has wet your apetite, please read my next post about deploying PHP applications with Webistrano. Also, feel free to leave your comments below.

I hope you found this post useful. God forbid your wiki database crashed, and you lost all the steps! One click deployment means faster, less buggy deployment.

You can even ask your Jimmy to deploy the lovely application for you. Capistrano is an open source tool that allows to run scripts on multiple servers. Capistrano automates the process of making new versions of an application as well as supporting tasks such as updating databases, rsyncing media assets etc.

It provides a descriptive interface for your projects and stages, and easy way to add environment specific settings. Now we need to configure it before we build it with rake. Two files that we need to copy: database database.

And the last, but not least, before we start the build. Webistrano creates all the stylesheets on the first run, so the public folder has to have writeable permissions:. You will have to install an older version of the bundler.

Gems allows you to keep different versions of the same package so this won't clash with your other ruby applications:. If this was successful, or you haven't had any issues with your bundler, simply run bundle install. To ensure that the same versions of the gems you developed with and tested with are also used in deployments, a Gemfile.

This is mainly to ensure that you remember to check your Gemfile. In development, you can modify your Gemfile 5 and re-run bundle install to conservatively update your Gemfile. In deployment, your Gemfile. In development, it's convenient to share the gems used in your application with other applications and other scripts that run on the system. In deployment, isolation is a more important default. In addition, the user deploying the application may not have permission to install gems to the system, or the web server may not have permission to read them.

This may be overridden using the --path option. In some cases, that location may not be writable by your Unix user. In that case, Bundler will stage everything in a temporary directory, then ask you for your sudo password in order to copy the gems into their system location. You should never use sudo bundle install. This is because several other steps in bundle install must be performed as the current user:.

The third, however, can only be performed by invoking the git command as the current user. As a result, you should run bundle install as the current user, and Bundler will ask for your password if it is needed to put the gems into their final location. By default, bundle install will install all gems in all groups in your Gemfile 5 , except those declared for a different platform.

However, you can explicitly tell Bundler to skip installing certain groups with the --without option. This option takes a space-separated list of groups.

While the --without option will skip installing the gems in the specified groups, it will still download those gems and use them to resolve the dependencies of every gem in your Gemfile 5.

This is so that installing a different set of groups on another machine such as a production server will not change the gems and versions that you have already developed and tested against. Bundler offers a rock-solid guarantee that the third-party code you are running in development and testing is also the third-party code you are running in production.

You can choose to exclude some of that code in different environments, but you will never be caught flat-footed by different versions of third-party code being used in different environments. For a simple illustration, consider the following Gemfile 5 :. When you run bundle install --without production in development, we look at the dependencies of rack-perftools-profiler as well. That way, you do not spend all your time developing against Rack 2.

This should not cause any problems in practice, because we do not attempt to install the gems in the excluded groups, and only evaluate as part of the dependency resolution process. This also means that you cannot include different versions of the same gem in different groups, because doing so would result in different sets of dependencies used in development and production.

Because of the vagaries of the dependency resolution process, this usually affects more than the gems you list in your Gemfile 5 , and can surprisingly radically change the gems you are using. When you run bundle install , Bundler will persist the full names and versions of all gems that you used including dependencies of the gems specified in the Gemfile 5 into a file called Gemfile.

Bundler uses this file in all subsequent calls to bundle install , which guarantees that you always use the same exact code, even as your application moves across machines. Because of the way dependency resolution works, even a seemingly small change for instance, an update to a point-release of a dependency of a gem in your Gemfile 5 can result in radically different gems being needed to satisfy all dependencies. If you do not, every machine that checks out your repository including your production server will resolve all dependencies again, which will result in different versions of third-party code being used if any of the gems in the Gemfile 5 or any of their dependencies have been updated.

When Bundler first shipped, the Gemfile. Over time, however, it became clear that this practice forces the pain of broken dependencies onto new contributors, while leaving existing contributors potentially unaware of the problem. Since bundle install is usually the first step towards a contribution, the pain of broken dependencies would discourage new contributors from contributing. As a result, we have revised our guidance for gem authors to now recommend checking in the lock for gems.

When you make a change to the Gemfile 5 and then run bundle install , Bundler will update only the gems that you modified. In other words, if a gem that you did not modify worked before you called bundle install , it will continue to use the exact same versions of all dependencies as it used before the update. Let's take a look at an example. Here's your original Gemfile 5 :. In this case, both actionpack and activemerchant depend on activesupport.
