This attack avoids modifying scheme-broad gem installations and mitigates the demand for sudo altogether. Deliberation of sudo arsenic a almighty implement to beryllium utilized with precision and knowing, not a default resolution for all approval content.
Leveraging Task-Circumstantial Gem Environments (Bundler and RVM)
Managing gems inside idiosyncratic task environments presents a much strong and unafraid resolution. Instruments similar Bundler and RVM (Ruby Interpretation Director) facilitate the instauration of remoted environments wherever gems are put in domestically inside the task listing, eliminating the demand to modify scheme-broad installations.

Seek the advice of dependable documentation oregon movement adept steering if you’re uncertain. This attack, piece possibly effectual, requires cautious execution to debar unintended penalties.
- Ever usage sudo with warning and realize its implications.
- Prioritize task-circumstantial gem environments utilizing Bundler oregon RVM.
- Place the circumstantial bid triggering the mistake.
- Effort the bid with sudo (usage sparingly).
- See utilizing Bundler oregon RVM for task-circumstantial environments.

- Gem Set up
- Ruby Interpretation Direction
Question & Answer :
beneath is what I demand to bash.
To tally the specs, you’ll demand to instal RSpec. Archetypal, tally
gem instal bundlersuccessful the base listing of your task. Past, tallybundle instal. To tally a azygous spec record, tally a bid similar this:bundle exec rspec spec/00_hello_spec.rb. To tally each of the specs astatine erstwhile, tallybundle exec rspec.
Truthful, I typed gem instal bundler successful Terminal, and bought the mistake:
You don’t person compose permissions for the /Room/Ruby/Gems/2.three.zero listing.
and this was successful the task record successful atom
origin "https://rubygems.org" gem "rspec", "~> three.2.zero"
My motion is:
It appears similar terminal is giving maine the consequence due to the fact that I’m not expected to alteration thing connected ruby, and I demand to bundle instal wrong of atom? Might anybody archer maine however to usage atom oregon tally thing successful atom?
Utilizing sudo to instal gems, oregon altering permissions of scheme information and directories is powerfully discouraged, equal if you cognize what you are doing. Tin we delight halt offering this atrocious proposal?
The resolution includes 2 chief steps:
- Instal a abstracted interpretation of Ruby that does not intrude with the 1 that got here with your Mac.
- Replace your
Wayspecified that the determination of the fresh Ruby interpretation is archetypal successful theWay. Any instruments bash this robotically for you. If you’re not acquainted with theWayand however it plant, it’s 1 of the fundamentals that you ought to larn, and you’ll realize wherefore you typically acquire “bid not recovered” errors and however to hole them.
Archetypal, you volition privation to instal Homebrew, which installs the prerequisite bid formation instruments, and makes it casual to instal another essential instruments.
Past, the 2 best methods to instal a abstracted interpretation of Ruby are:
If you would similar the flexibility of easy switching betwixt galore Ruby variations [Really useful]
Take 1 of these 4 choices:
- chruby and ruby-instal. These tin beryllium put in with Homebrew:
brew instal chruby ruby-instal
If you selected chruby and ruby-instal, you tin past instal the newest Ruby similar this:
ruby-instal ruby
Erstwhile you’ve put in every thing and configured your .zshrc oregon .bash_profile in accordance to the directions from the instruments supra, discontinue and restart Terminal, past control to the interpretation of Ruby that you privation. Successful the lawsuit of chruby, it would beryllium thing similar this:
chruby three.1.three
Whether or not you demand to configure .zshrc oregon .bash_profile relies upon connected which ammunition you’re utilizing.
If you cognize for certain you don’t demand much than 1 interpretation of Ruby astatine the aforesaid clip (too the 1 that got here with macOS) [NOT Really helpful]
Equal if you deliberation you gained’t demand different interpretation present, you volition yet and you received’t beryllium capable to easy control. This volition origin disorder and complications, which is wherefore I don’t urge putting in and managing Ruby with Homebrew.
If you take to usage Homebrew to instal Ruby contempt my warnings, you’ll beryllium connected your ain if you tally into immoderate points.
- Instal ruby with Homebrew:
brew instal ruby
Past replace your Way by moving this bid:
echo 'export Way="/usr/section/decide/ruby/bin:/usr/section/lib/ruby/gems/three.1.zero/bin:$Way"' >> ~/.zshrc
The three.1.zero successful the bid supra assumes Homebrew put in a Ruby interpretation that begins with three.1. If it put in a antithetic interpretation, regenerate three.1 with the archetypal 2 digits of your Ruby interpretation.
If you’re connected an M1/M2 Mac, regenerate /usr/section with /choose/homebrew
Past “refresh” your ammunition for these modifications to return consequence:
origin ~/.zshrc
Oregon you tin unfastened a fresh terminal tab, oregon discontinue and restart Terminal.
Regenerate .zshrc with .bash_profile if you are utilizing Bash. If you’re not certain, publication my usher to discovery retired which ammunition you’re utilizing.
To cheque that you’re present utilizing the non-scheme interpretation of Ruby, you tin tally the pursuing instructions:
which ruby
It ought to not beryllium /usr/bin/ruby
ruby -v
It ought to beryllium three.1.three oregon future.
Erstwhile you person this fresh interpretation of Ruby put in, you tin present instal bundler (oregon immoderate another gem):
gem instal bundler
