I am running OS X 10.11.6 and I installed Jekyll (using the already existent ruby on my system) by the recommended method: sudo gem install -n /usr/local/bin/ jekyll.
I can happily run jekyll on my system so I made a new site by running jekyll new TestSite which successfully executed.
However, this is where it stops working: if I cd into the site directory and run any jekyll command I get the following error:
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- bundler (LoadError)

Any ideas how to get it working?
It seems you don't have bundler gem. Try
gem install bundler

What must I do when I want to copy an installed gem from one installation to another one without using the gem command?
I have to install SQLite3 on a server without an internet connection. Normally I can do it with a copy of the gem-file:
gem install --local sqlite3-1.4.0.gem --platform ruby
But for SQLite3 it needs a connection to the internet to get libraries to compile some binaries. The installation worked well on a computer with an internet connection.
So my idea was to take my successful installation on the same OS and same Ruby version and copy all the related components, but this did not work.
When I called:
require 'sequel'
db = Sequel.sqlite
I got this error:
LoadError: The specified module could not be found

What is my error?
I'm using Windows Server 2016.
I found a precompiled version of SQLite3 in a GitHub issue which works for me, but I would like to use a newer version.
Use Bundler for this.
In short:
Run gem install bundler on each machine you're using.
Maintain a project Gemfile listing all requirements
Run bundle install when your Gemfile changes and bundle update to update to latest versions. This will generate the Gemfile.lock file.
Prefix ruby execution with bundle exec, e.g. bundle exec ruby myscript or bundle exec rails c
That's a brief summary, but please read up more on Bundler. It's an essential part of modern Ruby deployment.
You need to use the package option of bundler.
First you need to cache your dependencies into vendor/cache with:
bundle package --all --all-platforms
This will install all the dependencies of your Gemfile locally, then add the directory to your source code repository.
When deploying make sure you use bundle install --local to use the local version.
See the documentation for bundle package for more information.
on a mac os 10.12.6 after i try sudo gem install rake or
i get this error message:

The is error throws any gem install
Ruby version is 2.0.0, Ive tried updating ruby with homebrew but whni try installing home brew i get the same error.
Cant seem to edit /Library/Ruby/Site/2.0.0/rubygems.rb:1395
This is possibly related to issue #2535 in rubygems fixed in release 3.0.1.
Try gem update --system
All suggested solutions didn't fully work for me, although gem update --system seems to be a good idea, because it updates ruby. BUT: On my Mac, the system version didn't step back after the update, although ruby -v gave the correct new version. The described error remained for me, e.g. while using homebrew with brew update:
$ brew update

The only thing that helped me was the following as described here:
sudo rm -f '/usr/local/bin/update_rubygems'
sudo rm -rf '/Library/Ruby/Site/2.3.0'
Hope to help some folks (I'am on MacOS 10.14.2).
You are going to have problems using system ruby or messing with it's gems. You are far better off to use a ruby version manager where you may have different versions of ruby per project. I highly recommend RVM.
See here for how to install
Did you also try to run gem install bundler?
Post output of these commands if they don't give you an error
ruby -v

gem env
I'm trying to install and run puma.
My gemfile has the local extracted gems (the server has no internet access and bundler is install via gem install):
gem 'rack', '=2.0.3', :path => "/opt/app-root/src/gems/rack-2.0.3"
gem 'puma', '=3.11.0', :path => "/opt/app-root/src/gems/puma-3.11.0"
I run bundle like so:
bundle install --local --path ./bundle --deployment
Which produces:
Using bundler 1.16.1
Using puma 3.11.0 from source at `/opt/app-root/src/gems/puma-3.11.0`
Using rack 2.0.3 from source at `/opt/app-root/src/gems/rack-2.0.3`
Bundle complete! 2 Gemfile dependencies, 3 gems now installed.
Bundled gems are installed into `./bundle`
Then running:
bundle exec "puma --config puma.cfg"
Produces the problem with the missing ext:

I can find very little information about this issue, except this post https://github.com/bundler/bundler/issues/5398 which may or may not be a similar issue - but I don't know how to resolve it (re-running bundler install doesn't help me!)
By the way, the ext is present in the extracted gem as you'd expect:
opt/app-root/src/gems/puma-3.11.0/ext/puma_http11
The puma11 stuff in ext is a compiled library; the result of that compilation as puma_http11.bundle then gets copied to the lib/puma directory, as part of the installation process. Do you have this .bundle file?
I'm guessing you have a problem or missing steps in your local extraction process to build or copy the native code portions of Gems (including this one) - the Rakefile in the puma repository on Github includes steps to build the native pieces using ragel.
I am trying to run a simple example script from here, but even after installing requisite gems with no errors I get an error when running the script. It looks like libta_lib.so cant be found, but nothing in the install commands below had an error. Any idea what I am missing? Im happy to provide more data if needed, I just dont know what would be useful.
I ran:
#compiling ta-lib from source
gem uninstall talib_ruby
gem uninstall ta-indicator
make clean
sudo ./configure LDFLAGS="-lm"
sudo make
sudo make install
gem install talib_ruby
gem install ta-indicator

As per this follow these steps
sudo gedit /etc/ld.so.conf
Append below line and save:
include /usr/local/lib
run sudo /sbin/ldconfig
This was working fine and then suddenly it wasn't. I wish i knew why. Really stuck and cannot find anything online. I'm working on an ObjectiveC project. I've tried reseting everything with:
$ sudo gem uninstall ruby
$ sudo gem uninstall cocoapods
then
$ sudo gem install ruby
$ sudo gem install cocoapods
$ sudo gem update ruby
$ sudo gem update cocoapods
then i when in my projects directory i run
$pod install
and get the following error. I get this on all projects.

I reinstalled cocoa pods by running
$ sudo gem uninstall cocoapods-core cocoapods-downloader cocoapods
$ sudo gem install cocoapods
That resolved the issue for me
Looks like you're missing one of CocoaPod's dependencies. You should be able to install it with:
[sudo] gem install cocoapods-core
You should stop using "sudo" for tasks such as "gem install" etc. Here is a little tutorial on how to fix your ruby to ensure that you are not going to see issues with permissions for cocoapods (and other gems):
