Как обновить ruby

Как обновить Ruby на CentOS

Вопрос. Я установил пакет Ruby с rubygems в CentOS 6.5. Когда я пытаюсь запустить приложение Ruby, оно не запускается, потому что моя система CentOS не соответствует требованиям к минимальной версии Ruby (1.9 и выше). Как я могу обновить Ruby на CentOS?

В CentOS 6.5 установленная версия Ruby по умолчанию — 1.8.7. Некоторым приложениям Ruby требуется Ruby версии 1.9 и выше, поэтому они не могут нормально работать на стандартной CentOS. Чтобы обновить Ruby на CentOS, вы можете собрать и установить Ruby из исходного кода.

Если вы уже установили пакеты ruby и ruby-devel с yum , сначала удалите их перед обновлением Ruby.

$ sudo yum remove ruby ruby-devel

Соберите и установите последнюю версию Ruby из исходного кода следующим образом.

$ sudo yum groupinstall "Development Tools" $ sudo yum install openssl-devel $ wget http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.2.tar.gz $ tar xvfvz ruby-2.1.2.tar.gz $ cd ruby-2.1.2 $ ./configure $ make $ sudo make install

Наконец, обновите Rubygems и Bundler.

$ sudo gem update --system $ sudo gem install bundler

Если у вас есть какие-либо предварительно установленные драгоценные камни с более старой версией Ruby, обновите драгоценные камни.

$ sudo gem update

Чтобы использовать установленный Ruby/Rubygems, откройте новый терминал. Затем проверьте версию установленных Ruby и Rubygems следующим образом.

$ ruby --version $ rubygems --version

Устранение неполадок

1. Когда я запускаю команду gem после обновления Ruby, я получаю следующую ошибку.

ERROR: While executing gem . (Gem::Exception) Unable to require openssl, install OpenSSL and rebuild ruby (preferred) or use non-HTTPS sources

Чтобы решить эту проблему, вам необходимо собрать и установить расширение Ruby для OpenSSL из исходного кода следующим образом.

$ sudo yum install openssl-devel $ cd ruby-2.1.2/ext/openssl/ $ ruby extconf.rb $ make top_srcdir="../../" $ sudo make install top_srcdir="../../"

Как правильно перейти на новую версию Ruby on Rails

Эдик 2017-09-21T16:25:50+03:00

Ниже приведена “шпаргалка” на тему перевода Ruby on Rails проекта на новую версию Rails. Итак, по шагам:

1. Сначала желательно обновить Ruby gem менеджер:

$ gem update --system

2. Указываем новый gemset для новой версии Rails в .ruby-gemset (если вы используете такую схему указания гемсетов). При этом новую версию Rails можно уточнить тут – https://rubygems.org/gems/rails)

название-приложения-rails-версия

3. Создаем новый gemset (для этого можно просто выйти и снова войти в папку приложения)

4. Обновить версию Rails в Gemfile

gem 'rails', '4.2.1'

5. Обновить все темы, сначала удалить файл Gemfile.lock, а потом запустив команду

bundle install

6. Теперь нужно обязательно не забыть обновить конфигурационный файлы Rails:

$ bin/rake rails:update

При этом не стоит бездумно переписывать файлы конфигурации, так как в них содержатся внесенные вами ранее изменения. Для отслеживания изменений используйте клавишу d. Если изменения коснутся данных, внесенных вами, – придется потом снова их вводить! Сохраняйте информацию по этим изменениям заблаговременно.

How can I update Ruby version 2.0.0 to the latest version in Mac OS X v10.10 (Yosemite)?

I need to update my Ruby version from 2.0.0 to the latest version. I can not use some gems because my version is not updated. I had used Homebrew to install Ruby some time ago. How can I update my Ruby version?

Open your terminal and run

curl -sSL https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer | bash -s stable

For the rvm command to work, you need to run:

source ~/.rvm/scripts/rvm

Now, run rvm list known

This shows the list of versions of the Ruby interpreter.

Now, run rvm install ruby@latest to get the latest Ruby version.

If you type ruby -v in the terminal, you should see ruby X.X.X .

If it still shows you ruby 2.0. , run rvm use ruby-X.X.X —default .

Prerequisites for Windows 10:

C compiler. You can use http://www.mingw.org/
make command available otherwise it will complain that «bash: make: command not found». You can install it by running mingw-get install msys-make
Add «C:\MinGW\msys\1.0\bin» and «C:\MinGW\bin» to your path environment variable

2.2.0 is not the latest version of Ruby.
Jul 5, 2016 at 2:04
@Jordan My bad 2.3 is the stable version
Jul 5, 2016 at 2:09
This works on Mac OS to install RVM: \curl -sSL https://get.rvm.io | bash -s stable —ruby
Dec 28, 2016 at 16:04
2.4 is the latest stable version: rvm install ruby-2.4.0

piping curl output straight to execution is a security nightmare waiting to happen.

Brew only solution

A better solution

From the comments (kudos to Maksim Luzik), I haven’t tested but seems like a more elegant solution:

After installing Ruby through brew, run the following command to update the links to the latest Ruby installation: brew link —overwrite ruby

A solution

Using brew is enough. It’s not necessary to install rvm and for me it just complicated things.

By brew install ruby you’re actually installing the latest (currently v2.4.0). However, your path finds 2.0.0 first. To avoid this just change precedence (source). I did this by changing ~/.profile and setting:

After this, I found that the bundler gem was still using version 2.0.0. Just install it again: gem install bundler

Exactly what I was looking for, thanks. If I was a ruby dev then rvm would make sense, but I’m not, so this is perfect.

this works, needed to do «source ~/.bash_profile» after install

instead of overwrite ruby version, you can just write brew unlink ruby && brew link ruby

rbenv does…

Provide support for specifying application-specific Ruby versions.
Let you change the global Ruby version on a per-user basis.
Allow you to override the Ruby version with an environment variable.

In contrast with RVM, rbenv does not…

Need to be loaded into your shell. Instead, rbenv’s shim approach works by adding a directory to your $PATH .
Override shell commands like cd or require prompt hacks. That’s dangerous and error-prone.
Have a configuration file. There’s nothing to configure except which version of Ruby you want to use.
Install Ruby. You can build and install Ruby yourself, or use ruby-build to automate the process.
Manage gemsets.Bundler is a better way to manage application dependencies. If you have projects that are not yet using Bundler you can install the rbenv-gemset plugin.
Require changes to Ruby libraries for compatibility. The simplicity of rbenv means as long as it’s in your $PATH , nothingelse needs to know about it.

INSTALLATION

Install Homebrew http://brew.sh

$ brew update $ brew install rbenv ruby-build # Add rbenv to bash so that it loads every time you open a terminal echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile source ~/.bash_profile

$ rbenv install --list Available versions: 1.8.5-p113 1.8.5-p114 […] 2.3.1 2.4.0-dev jruby-1.5.6 […] $ rbenv install 2.3.1 […]

Set the global version:

$ rbenv global 2.3.1 $ ruby -v ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]

If you are not showing the updated version then

$ rbenv rehash

Set the local version of your repository by adding .ruby-version to your repository’s root directory:

$ cd ~/whatevs/projects/new_repo $ echo "2.3.1" > .ruby-version

@ChuchaC No prob. But before you do, this is from the rbenv readme: «Compatibility note: rbenv is incompatible with RVM. Please make sure to fully uninstall RVM and remove any references to it from your shell initialization files before installing rbenv.» — github.com/rbenv/rbenv#installation

Jul 6, 2016 at 2:33
didn’t helped. Still getting standard 2.0.0 version for ruby -v after rbenv global .
Sep 8, 2016 at 10:57

There’s one additional step after brew install rbenv Run rbenv init and add one line to .bash_profile as it states. After that reopen your terminal window, do rbenv install 2.3.1 , rbenv global 2.3.1 and rbenv will do its work

Probably late but for future references for people who encountered the same issue as @tuxSlayer , rbenv rehash after rbenv global worked for me

Feb 1, 2017 at 3:01

After rbenv init , ruby -v outputs the correct version 2.1.2, but bundle runs encounters some error like this paperclip-5.0.0.beta1 requires ruby version >= 2.1.0, which is incompatible with the current version, ruby 2.0.0p648 . Finally manage to get it work with a run of rbenv rehash . Thanks @Sean

This does indeed seem to work, and is a unmeasurably more straight forward than the other answers. But when installing some gems (listen for example) they complain that the version is lower than required.

I was misled by this answer too. It «works» in that no errors are generated when you run it from the console. However, it does not update Ruby. It updates Ruby Gems. Follow one of the other answers to update Ruby (using OS X Sierra).

Tried it, but i got the following error: ERROR: Error installing rubygems-update: rubygems-update requires Ruby version >= 2.3.0. ERROR: While executing gem . (NoMethodError) undefined method `version’ for nil:NilClass

This appears to do a ton of stuff, but upgrading ruby isn’t one of them. It terminates with: /usr/local/Homebrew/Library/Homebrew/brew.rb:12:in ‘

‘: Homebrew must be run under Ruby 2.3! You’re running 2.0.0. (RuntimeError)

@SébastienLoisel can you please give some detail about your OS, command etc.
Mar 20, 2020 at 10:15

@fatihyildizhan apparently ruby/gems/etc is in a semibroken state on Mavericks. I’ve resolved my issues by upgrading to Catalina. I don’t remember all the errors I had, but there were multitudes. I can’t remember if I was trying to upgrade cocoapods or gems or what, but it was essentially hopeless.

You can specify the latest version of Ruby by looking at Download Ruby.

curl -sSL https://get.rvm.io | bash -s stable --ruby

rvm install 2.2

rvm use 2.2 --default

Or run the latest command from ruby:

rvm install ruby --latest rvm use 2.2 --default

Add rbenv to Bash so that it loads every time you open a terminal:

Install Ruby

rbenv install 2.6.5

✅ Working 2023 method:

Upgrade using the homebrew:

brew upgrade ruby echo 'export PATH="/opt/homebrew/opt/ruby/bin:$PATH"' >> ~/.zshrc brew link --overwrite ruby

Then restart the Terminal (make sure you terminate all instances, quit and open again)

Then ruby -v to check if it linked correctly.

��Recommended Followup:

It’s not required but you can run the following after upgrading the ruby to update gem files:

gem update --system 3.4.2

_{⚠️ The above version may be changed when you have upgraded your ruby. Please use the correct version as reported after the installation of the ruby.}

this assumes zshell, which while the default shell on newer macs, many still use bash.
Nov 15 at 20:05

In case of the error “Requirements installation failed with status: 1.”, here’s what to do:

Install Homebrew (for some reason it might not work automatically) with this command:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then proceed to install rvm again using

curl -sSL https://get.rvm.io | bash -s stable --ruby

Quit, reopen Terminal, and then:

rvm install 2.2 rvm use 2.2 --default

I ended up using the steps below due to React Native 0.70 and macOS v12 (Monterey).

brew install ruby

open -e ~/.zshrc

Set the $PATH environment variable. Add this at the end of your ~/.zshrc file. On Mac Intel:

if [ -d "/usr/local/opt/ruby/bin" ]; then export PATH=/usr/local/opt/ruby/bin:$PATH export PATH=`gem environment gemdir`/bin:$PATH eval "$(rbenv init -)" fi

if [ -d "/opt/homebrew/opt/ruby/bin" ]; then export PATH=/opt/homebrew/opt/ruby/bin:$PATH export PATH=`gem environment gemdir`/bin:$PATH eval "$(rbenv init -)" fi

Don’t want brew to update your version?
