I'm trying to setup ruby using rbenv on a server, instead of the apt-get installed version of ruby and bundler.

I followed Digital Ocean's guide, deviating only on ruby version (I need 2.7.1) and ruby installation path (PREFIX=~/local ./ruby-build/install.sh) to keep everything in my home folder because I'm not root.

What worked

  • Installing rbenv
  • Installing ruby-build
  • rbenv install 2.7.1
  • rbenv shell 2.7.1
  • rbenv global 2.7.1
  • bundle install
  • sudo apt-get purge ruby

However bundle exec rake does not run, and returns the following error:

/usr/bin/env: ‘ruby2.7’: No such file or directory

$ rbenv exec bundle exec ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux]

$ rbenv exec bundle exec rake
Your Ruby version is 2.7.0, but your Gemfile specified 2.7.1

When I simply run rake in my application folder (without going through bundle exec) I get the following error:

$ rake
rake aborted!

It looks like running rbenv exec bundle exec rake [command] actually calls /usr/local/bin/bundle instead of rbenv's shim, despite having .rbenv/shims and .rbenv/bin first in my PATH.

Any idea why, and how to work around that?

Things I've tried already

  • gem update --system
  • rbenv rehash
  • removing and reinstalling rbenv entirely
  • installing ruby 2.7.0 through rbenv

Here's my environment:

$ echo $PATH
/home/gchampenois/.rbenv/shims:/home/gchampenois/.rbenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

$ lsb_release -a | grep 'Description'
Description:    Ubuntu 20.04.2 LTS


$ rbenv versions


    

  • 2.7.1 (set by RBENV_VERSION environment variable)
    • 



$ which -a bundle
/home/gchampenois/.rbenv/shims/bundle
/usr/local/bin/bundle
/usr/bin/bundle
/bin/bundle


$ which -a gem
/home/gchampenois/.rbenv/shims/gem


$ which -a ruby
/home/gchampenois/.rbenv/shims/ruby


$ ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux]


$ cat /usr/local/bin/bundle
#!/usr/bin/ruby2.7

I solved this by removing everything in <app_name>/vendor/bundle

rm -rf <app_name>/vendor/bundle

making sure that in my Gemfile I had

ruby '2.7.0'

and then.

gcloud config set app/cloud_build_timeout 86400

gcloud app deploy
