Specify bundler executable location

[craibuc]

I'm using a shared hosting environment that has 3 version of Ruby installed: 2.0, 2.22, and 2.33. I'm using 2.33 in my application. Unfortunately, they don't use rvm or rbenv to manage this.

As a result, I need to use specific bundler settings to get my Gems installed in their environment:

app_dir$ /usr/local/bin/ruby233 /usr/local/bin/bundle233 --path vendor/bundle

When run manually (via ssh), this installs the Gems in the app_dir/shared/vendor/bundle directory.

How would I represent /usr/local/bin/ruby233 /usr/local/bin/bundle233 --path vendor/bundle in capistrano/bundler?

[mattbrictson]

I'd suggest customizing the bundle command via the SSHKit command-map, like this:

# put this in deploy.rb
SSHKit.config.command_map[:bundle] = "/usr/local/bin/ruby233 /usr/local/bin/bundle233"

Does that work?

[craibuc]

Seems like it is interfering with the deploy:check:directories step for some reason.

[mattbrictson]

I'm curious why you added this?

require 'sshkit'
require 'sshkit/dsl'
include SSHKit::DSL

SSHKit is an inherent part of Capistrano and there is no need to require it. Try removing these lines and see what happens.

[craibuc]

Why did I include it? Lack of knowledge.

That worked.

Thanks for the help.

[mattbrictson]

Why did I include it? Lack of knowledge.

I just wanted to make sure there wasn't another problem you discovered that you had solved by requiring SSHKit. Apologies if that came off as passive-aggressive. 😅
