bundle install using old rubygems version - ruby

I'm having what appears to be the exact same problem seen in a 1-month old question that no one has touched. I installed rbenv using homebrew, installed ruby 2.3.1 using rbenv install 2.3.1, installed jekyll and bundler using gem install jekyll and gem install bundler, then within a jekyll project, I typed bundle install. I got the error Rubygems 2.0.14.1 is not threadsafe, so your gems will be installed one at a time. Upgrade to Rubygems 2.1.0 or higher to enable parallel gem installation. When I run gem env, I see this:
RubyGems Environment:

I don't understand why bundler complains about Rubygems being below 2.1.0 when my Rubygems version is 2.6.6.
There is a Gemfile and a Gemfile.lock in the project directory. Gemfile looks like this:
source 'https://rubygems.org'
# jekyll
gem "jekyll", "3.1.1"
gem "redcarpet"
# compiling less
gem 'therubyracer'
gem 'less'
# minifying
gem 'jekyll-press'
# octokit
gem 'octokit'
gem 'netrc'

Hi I am learing Rails and encountered the same issue and I don't know what the root cause it is. But when I try reinstall bundler again
gem install bundler
and then run
bundle install
everything goes fine now.

I don't know exactly what the issue was, but when I removed Gemfile.lock and reran bundle install everything worked fine. There were probably just some bad constraints or something in Gemfile.lock.

How to change gem environment for RUBY VERSION

I'm pretty new to Ruby and pod installation. Currently I have Ruby installed through RVM. However I'd like to install a pod through bundler by bundle exec pod install.
I keep getting the following error that my current version of Ruby is different from Gemfile specified. My current version of Ruby via RVM is same with Gemfile version. (So if I do pod install it won't cause any issues).
My gem env shows different Ruby Version.
How can I go about changing that? Where does gem env live? I saw some instructions here to install a RubyGem. But I'm having trouble following this. Any advice helps!
➜ ios git:(main) bundle exec pod install
Your Ruby version is 2.6.8, but your Gemfile specified 2.7.5

Ruby version and project not matching

When I run, bundle I see the following:
Your Ruby version is 2.5.0, but your Gemfile specified
2.4.0.pre.dev
my Gemfile looks like:
source 'https://rubygems.org'
ruby '2.4.0-dev'

This is my gem env:

When I type rbenv verions this is what I see:
system
2.0.0-p247
2.3.1
* 2.4.0-dev (set by /Users/johndoe/code/projects/blog-server/.ruby-version)
With Rbenv I am specifying the ruby version I want, and I am matching this in my project's Gemfile. However, whenever I run bundle or bundle exec gem uninstall sinatra I see the above error message about my ruby version and my gemfile ruby version not matching. I also see that my Ruby version is 2.5.0, and I have no idea how that got set. Can someone help me resolve this error?
Your Ruby version is 2.5.0, but your Gemfile specified
2.4.0.pre.dev
In my bash profile, I have:
export PATH=$HOME/.rbenv/bin:$PATH
....
eval "$(rbenv init -)"
In short, I just want the shell that runs my ruby process for my blog project to use ruby version 2.4.0-dev, and I am struggling to see understand what's blocking me and how to resolve it.
UPDATE:
I also noticed something odd. My bundler version continues to point to ruby 2.5.0p-1.
## Environment
Bundler 1.15.3
Rubygems 2.6.12
Ruby 2.5.0p-1 (2017-07-31 revision 59454) [x86_64-darwin16]
Git 2.11.0
Platform x86_64-darwin-16
OpenSSL OpenSSL 1.0.2k 26 Jan 2017
```
## Gemfile
### Gemfile
```ruby
source 'https://rubygems.org'
ruby '2.4.0-dev'
gem 'sinatra', '2.0.0'
```
### Gemfile.lock
```
<No /Users/johndoe/code/projects/blog-server/Gemfile.lock found>
In a project folder run:
rbenv local 2.4.0-dev
It should do the trick. You just need to specify local ruby version for this particular project. And your global version is set to 2.5.0
The best option here, I think, is to install Ruby Version Manager (rvm).
RVM helps every ruby developer by doing exactly what you need; manage ruby version automatically as you need.

Where is the "Gemfile" in Ruby?

I often see in documentation on the Internet, "put this in the Gemfile". I don't know where and what this "Gemfile" is. If I install a gem then I have installed it. Who need than a "Gemfile"? Where or what is the Gemfile, and why is it used?
The Gemfile is wherever you want it to be - usually in the main directory of your project and the name of the file is Gemfile.
It's convenient to have one because it allows you to use Bundler to manage which gems and which versions of each your project needs to run.
If you are not using Bundler (which you should!), then you can just install any gems you come across with gem install X and ignore instructions about adding a line to your Gemfile.
Read more about it here:
http://bundler.io/gemfile.html
http://bundler.io/man/gemfile.5.html
Gemfile is in Rails project, for Ruby run gem environment to find out about your gem environment:

Gemfile is a file which must be located in root of your rails project. It is used for describing gem dependencies for Ruby programs.
The first thing in your gemfile is a source in which you tell the Gemfile where to look for gems.
Source can be called as a block and you can have multiple sources in your gemfile.
source "https://my_awesome_source.com" do
gem "my_gem"
gem "my_other_gem"
end
Here is some documentation where you can read more about gemfile
http://bundler.io/gemfile.html
Just run gem update --system and you're good to go. It's that easy!!!

Maybe bundler is looking in the wrong gem paths? Is there a way to see which paths it is using?
It works when I manually add the dependencies to LOAD_PATH in Gemfile; maybe this helps to point me to the cause of the problem:
[ 'bundler-bower-0.0.3', 'bower-rails-0.10.0'].each do |dep|
$LOAD_PATH.unshift "/Users/nobby/.rvm/gems/ruby-2.3.0/gems/#{dep}/lib"
end
https://github.com/LTe/bundler-bower
You need to
gem install 'bundler-bower'
before you can require modules from it. Potentially (hopefully) bundler is clever enough to resolve dependency order if you add
gem 'bundler-bower'
to your gemfile and then install it with
bundle install
instead

public_suffix not getting installed while running bundle install jekyll github-pages

I have a blog of mine in jekyll and I want to publish it on github-pages.
Taking reference from here:
https://help.github.com/articles/using-jekyll-with-pages.
but I am getting this error while running bundle install
Gem::InstallError: public_suffix requires Ruby version >= 2.0.
An error occurred while installing public_suffix (1.5.1), and Bundler cannot continue.
Make sure that `gem install public_suffix -v '1.5.1'` succeeds before bundling.

Just like you my ruby version was correct, but the fix for me was reinstalling bundler.
sudo gem install bundler
Try installing without sudo.
I've had the same issue after upgrading Ruby to 2.2.3 with rbenv (which is installed without admin rights).
After having upgraded, I ran sudo gem install github-pages, which resulted in the above error. Running gem install github-pages worked just fine.
Then, trying to have Jekyll serve my page, I ran bundle exec jekyll serve, which told that there were some bundles missing. bundle install fixed that too, and bundle exec jekyll serve worked fine.
Make sure that gem install public_suffix -v '1.5.1' succeeds before bundling.
I had the same issue and this command solves it.
sudo gem install github-pages -v 33
Then run jekyll.
bundle exec jekyll serve
See here
In the past i've also had issues with installing github pages or Jekyll dependencies because there is a space somewhere in the full path to your project folder and apparrently some of the dependencies cant handle spaces in filenames.
Most recently this seems to have been happening to me with public_suffix version 4.0.5 where a space in my username causes it to break
This has also happened with http_parser
