# TIL: Bundle install with a specific version of Bundler

The challenge with working on multiple Ruby on Rails projects is coming across issues conflicting dependencies between projects. One issue I have been having has been with the version of `bundler`. One project I am working on depends on `bundler v2` and another depends on `bundler v1` running on the same Ruby version.

Upgrading `bundler` version for the project using `bundler v1` is not an option right now and trying to do any `bundle installs` can get very annoying since it will be using the wrong version of `bundler` for the `Gemlock`.

After doing some web searching for a potential solution I found out about this funky annotation for telling `bundle` what version of the `bundler` gem you would like to use:  

```bash
bundle _1.13_ install
```

It's a weird argument but it works. So next time you have a different major `bundler` versions across projects try using this.
