Unable to deploy to production due to rails 5.0.1 conflict with bundler 2 #24

Closed jjmountain closed 3 years ago

jjmountain commented 5 years ago

Rails 5.0.1, which the base app is made in, requires (bundler (< 2.0, >= 1.3.0)). However, the current bundler version is 2.0.1 which is not within this requirement.

I tried uninstalling bundler with gem uninstall bundler and then installed the last version that should work with gem install bundler --version 1.17.3. That worked and I was able to bundle install successfully.

However when I deploy to production in heroku it crashes half-way through installing the gems with this message in the terminal output:

Downloading rails-5.0.1 revealed dependencies not in the API or the lockfile remote: (bundler (< 2.0, >= 1.3.0)). remote: Either installing with --full-index or running bundle update rails should remote: fix the problem.

I reasoned that the problem was with the gemfile.lock, but altering it to bundler ( = 1.17.3) doesn't solve this problem.

I tried to use all my technical sophistication (over a number of hours this evening) but I can't work out how to resolve this so I can deploy to heroku. The only other thing I can think of is upgrading rails.. but when I searched for this the page I checked said that rails version needs to be decided when you create the app.

Also, running bundle update rails as the terminal output suggests has no effect, simply yielding the output: Bundler attempted to update rails but its version stayed the same

I suggest trying this:

bundle _1.17.3_

That should tag the Gemfile.lock file with the version of Bundler used:

BUNDLED WITH
   1.17.3

Subsequent calls to bundle should then automatically use the correct version of Bundler.

See How to change the version of bundler being used in Rails? and How to Upgrade to Bundler 2 for more information.

I’ve also recently updated the application’s Gemfile, so you might want to see if using that helps as well.

I’ve recently updated the app’s Gemfile.lock to use Bundler 2.
