capistrano-nvm's Issues

Still active?

Hi,

I've started using this gem but I've noticed some features that I require (install node #27) are not present on the released versions.

Are you looking for maintainers for the project?

Thank you for the nice capistrano gem :)

Is nvm-exec.sh actually executed?

Hello folks,
got a weird behavior today:

as you can see /tmp/pufffer/nvm-exec.sh actually wasn't executed, and I can't find command to do that anywhere in

Is it a bug or I'm missing something?

Don't wrap certain tasks?

I have some non-node tasks that should not (or at least don't need to) be wrapped to use nvm. Is there a way to exclude certain tasks from having the nvm setup commands run?

Cannot deploy an application using Rails 5.1 Webpacker

Hi there!

It looks like capistrano-nvm is not playing well with Rails 5.1 Webpacker.

Rails started make ./bin/yarn a dependency for assets:precompile here: rails/rails@b1c08d8

.bin/yarn looks like this:

#!/usr/bin/env ruby
VENDOR_PATH = File.expand_path('..', __dir__)
Dir.chdir(VENDOR_PATH) do
  begin
    exec "yarnpkg #{ARGV.join(" ")}"
  rescue Errno::ENOENT
    $stderr.puts "Yarn executable was not detected in the system."
    $stderr.puts "Download Yarn at https://yarnpkg.com/en/docs/install"
    exit 1
  end
end

As you can see it does a direct system call to yarnpkg which is not found in the PATH. I am not sure what's the best way to go around this as Capistrano is not setting environment variables globally but use SSHKit instead. Any idea?

Thx for your help!

NVM multiple user install on Ubuntu

Might be a dumb question, but if I installed NVM in /home/myuser/.nvm how can I set it correctly?

This doesn't seem to work...

# Rails app --> deploy.rb
set :nvm_custom_path, '/home/myuser/.nvm'

The documentation isn't so clear and I cannot understand if I am wrong or if the problem I get comes from something else.

capistrano-nvm looks for nodejs in wrong directory

I've been trying to get my application deployed with Capistrano using nvm but it fails the nvm:validate task:
ERROR nvm: v0.12.5 is not installed or not found in $HOME/.nvm/v0.12.5
The problem is that NVM installs node to .nvm/versions/node/<version> instead

Doesn't work in nvm 0.30.2

https://github.com/koenpunt/capistrano-nvm/blob/master/lib/capistrano/tasks/nvm.cap#L31

In the latest version (v0.30.2) of nvm, this /tmp/.../nvm-exec.sh doesn't work.

Because /usr/local/nvm/nvm.sh removes arguments now:
nvm-sh/nvm@v0.30.1...v0.30.2#diff-e1e8e036966ad5aaf7709712cd5d8ee3R2372

For example:

nvm-echo.sh:

#!/bin/bash
source "/usr/local/nvm/nvm.sh"
echo "$@"

nvm 0.30.1

$ ./nvm-echo.sh node --version
node --version

nvm 0.30.2

$ ./nvm-echo.sh node --version

# it displays nothing

workaround

You can avoid this issue by setting nvm_prefix option:

set :nvm_prefix, "#{fetch(:nvm_path)}/nvm-exec"

I'll send a pull request later.

not working !

i added the following lines to my deploy/staging.rb

set :nvm_type, :user # or :system, depends on your nvm setup
set :nvm_node, 'v8.17.0'
set :nvm_map_bins, %w{node npm yarn}

added also require "capistrano/nvm" in my Capfile then i hit cap staging delploy the nvm:wrapper seemed to be running successfully but when compiling assets i can see

gyp ERR! node -v v14.5.0

which means that node version is not being changed to 8.17.0

any help ?

capistrano-nvm doesn't appear to be working with capistrano-bower

Hi, I'm deploying a Rails app that makes use of bower and nvm. The problem I'm having now, is that it appears that Capistrano is not running nvm.sh, without being able to find node during bower:install.
Does anyone know what the problem is here?

Capistrano output:
https://gist.github.com/ngw/5e6491071ef1ee364cebcd61b1347d38

Gemfile.lock:
https://gist.github.com/ngw/8b5b862915c288f618cd3420e707b598

Deploy.rb:
https://gist.github.com/ngw/3472dc3a2fac385da3f9c616a8f5a7a8

Does anybody have any idea what's happening here?

Possiblity to configure major version number only

It would be great to have the possibility to configure only the major version like:

set :nvm_node, 'v18'

By the way, thank you for your work on this gem.

Multiple deploy users on one VPS

Issue

I have multiple Rails applications running on single VPS, each of them deployed under different user.

capistrano-nvm fails on nvm-exec.sh manipulation, since it is already created in /tmp/<application> and belongs to another user.

Solution

Simple config option for the file destination would suffice.

Or better clean it up after deploy? (I haven't read the code thoroughly, so I'm not even sure, what the file is for.)
