BUNDLE-INJECT(1)

✨ NAME ✨

okay bestie, welcome to bundle-inject — the manual page for the bundle-inject command 💅 she's the one that adds named gem(s) with their version requirements straight into your Gemfile. yes queen, she writes to your Gemfile directly. we love a confident icon.

---

🎀 SYNOPSIS 🎀

bundle inject [GEM] [VERSION] [--source=SOURCE] [--group=GROUP]

that's it. that's the whole vibe check. GEM, VERSION, and two lil optional flags that we'll get to 🫶

---

💖 DESCRIPTION 💖

so what she does is: she takes the named gem(s), along with their version requirements, and adds them to your resolved Gemfile(5). ✨

and like, not just one file — this command will add the gem to both your Gemfile(5) and your Gemfile.lock if it isn't listed yet. both. she does both. main character behaviour fr fr 👑

here's the glow-up in action:

bundle install
bundle inject 'rack' '> 0'

what just happened? she injected the rack gem with a version greater than 0 into your Gemfile(5) and your Gemfile.lock. slay. 🍓

okay so real talk though — the bundle inject command was deprecated in Bundler 2.1 and will be removed in Bundler 3.0. 💀 i know. it's giving "we need to talk." she still works, but she's on her way out, so don't build your whole personality around her, bestie. no cap.

---

🌸 OPTIONS 🌸

• --source=SOURCE — install the gem from the given source. you're telling her where to grab it from 🧚
• --group=GROUP — install the gem into a bundler group. put her in a group, she's social like that 🌈

---

and that's the whole page, bestie!! every flag, every path, every little detail, all preserved and all iconic 💜
