Make sure that `gem install byebug -v '11.1.3' --source 'https://rubygems.org/'` succeeds before bundling

Question

I am trying to install the byebug gem for ruby on visual studio code and every time I try to use bundle install to install it, it gives me this error:

Errno::EACCES: Permission denied @ rb_sysopen -
/home/ja12tk/vendor/bundle/ruby/2.7.0/gems/byebug-11.1.3/CHANGELOG.md
An error occurred while installing byebug (11.1.3), and Bundler cannot continue.
Make sure that `gem install byebug -v '11.1.3' --source 'https://rubygems.org/'` succeeds
before bundling.

This is what the Gemfile says:

source "https://rubygems.org"

gem "byebug"
gem "rspec", "~> 3.2.0"

Along with the Gemfile.lock

GEM
  remote: https://rubygems.org/
  specs:
    byebug (11.1.3)
    diff-lcs (1.4.4)
    rspec (3.2.0)

PLATFORMS

DEPENDENCIES

BUNDLED WITH

I have even tried using "gem install byebug" and it give me this error:

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /var/lib/gems/2.7.0 directory.

Any help would be greatly appreciated

Answer 1

I had run into the same problem, but this is how I solved it

I ran

• sudo apt-get install ruby-dev on the root terminal
• then, bundle install under required Gemfile directory

That's all
