Using multiple Bundler versions

Question

I've joined a project which is using bundler version 1.17.1 . Currently my system is using bundler 2.0.2 . Is there any way for me to specify a bundler version just like specifying ruby version with rbenv. Something likes:

bundler --global 1.17.1

So that, when I run the command bundler -v I will receive the result 1.71.1 rather than 2.0.2

I tried to uninstall the current bundler with gem uninstall bundler and received this message:

$ gem uninstall bundler

Select gem to uninstall:
 1. bundler-1.17.1
 2. bundler-1.17.3
 3. bundler-2.0.2
 4. All versions
>

That makes me think there is a certain way allows me to work with multiple bundler versions. Any clues just for pointing me to where I should look up would be really appreciated.

I tried bundle _1.17.1_ --version and it didn't work as I expected

$ bundler -v
Bundler version 2.0.2
$ bundle _1.17.1_ --version
Bundler version 1.17.1
$ bundler -v
Bundler version 2.0.2

expected: Bundler version 1.17.1

actual: Bundler version 2.0.2

Try this:

1) gem install bundler -v 1.17.1

2) bundle _1.17.1_ install

Accepted! Looks like this is the only way: `bundle _1.17.1_ install` – You Nguyen Jul 08 '19 at 03:15
@NguyenYou It's nice that it helped :) – Miro Jul 08 '19 at 21:47
It doesn't work for me: `> file ~/.gems/gems/bundler-1.17.1` outputs `/Users/iulian/.gems/gems/bundler-1.17.1: directory` and `> bundle _1.17.1_ --version` outputs `Bundler version 2.0.2`. – Iulian Onofrei Nov 27 '19 at 10:05
This doesn't seem to work with version two alike: `bundle _2.*.*_ install`. – angerhang Mar 10 '20 at 21:59

@angerhang Have you tried ``bundle update --bundler`` ? – Miro Mar 13 '20 at 16:01
when I try to run ```bundle _1.3.0_ install``` on my machine, Im always getting Could not find command "_1.3.0_" – David Geismar May 23 '20 at 13:52
while using `bundle exec` which version will it use? – Juan José Ramírez Jan 14 '21 at 21:47

You can specify multiple bundler versions by using underscores: RubyGems already provides this functionality. Specify the version number in underscores as the first argument on the command line.

$ bundle _1.1.3_ --version
Bundler version 1.1.3
$ bundle _1.1.0_ --version
Bundler version 1.1.0
$ bundle _1.0.22_ --version
Bundler version 1.0.22

There's an issue in rbenv with a similar question: https://github.com/rbenv/rbenv/issues/235.

Hope this helps

This doesn't change the default. You need to add the version `_1.17.1_` every time you run the `bundle` command. Or if you want `bundle` command to point to this version every time, you can alias it in your rc file like `alias bundle='bundle _1.17.1_'`. – hchhabra Jul 04 '19 at 06:30
```bundle _1.3.0_ install``` returns ```Could not find command "_1.3.0_".``` – David Geismar May 19 '20 at 18:18
