$ rbenv install 2.6.1
ruby-build: definition not found: 2.6.1

See all available versions with `rbenv install --list'.

If the version you need is missing, try upgrading ruby-build:

  cd /Users/xxxxxx/.rbenv/plugins/ruby-build && git pull && cd -

だめだった。

ruby-build をアップグレードしてと言われたので、やってみる。

ruby-2.6.1 のインストール

$ rbenv install 2.6.1
ruby-build: use openssl from homebrew
Downloading ruby-2.6.1.tar.bz2...

ruby-build: use readline from homebrew
Installed ruby-2.6.1 to /Users/xxxxxx/.rbenv/versions/2.6.1

インストールされているか確認

$ rbenv versions
  system

  2.4.1
* 2.5.0 (set by /Users/xxxxxx/project/project_name/.ruby-version)
  2.5.1
  2.6.0-preview1
  2.6.1

.ruby-version 変更

.ruby-version のファイルで、Ruby のバージョンを管理していたので変更。

$ rbenv local 2.6.1

自動的に .ruby-version の中身が変更される。

# .ruby-version

-2.5.0
+2.6.1

ruby のバージョン確認

$ ruby -v
ruby 2.6.1p33 (2019-01-30 revision 66950) [x86_64-darwin17]

$ rbenv versions

bundle exec rails c

$ bundle exec rails c
rbenv: rails: command not found

The `rails' command exists in these Ruby versions:
  2.3.4
  2.4.1
  2.5.0
  2.5.1

できないので、Rails もアップデートする。

Rails のアップデート

Gemfile を変更。

# Gemfile
 ...
 gem 'puma', '~> 3.7'
-gem 'rails', '~> 5.1.4'
+gem 'rails', '~> 5.2.2'
 gem 'redis', '~> 3.0'
 gem 'redis-rails'
 ...

bundle update --conservative rails

--conservative をつけることで他の gem のアップデートを抑制することができます。

$ bundle update --conservative rails

Bundler could not find compatible versions for gem "activemodel":
  In snapshot (Gemfile.lock):
    activemodel (= 5.1.4)

  In Gemfile:
    counter_culture was resolved to 1.9.1, which depends on
      activerecord (>= 3.0.0) was resolved to 5.1.4, which depends on
        activemodel (= 5.1.4)

    rails (~> 5.2.2) was resolved to 5.2.2, which depends on
      activemodel (= 5.2.2)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

activemodel も update する。

Bundle updated!
Post-install message from yard:
--------------------------------------------------------------------------------
As of YARD v0.9.2:

RubyGems "--document=yri,yard" hooks are now supported. You can auto-configure
YARD to automatically build the yri index for installed gems by typing:

    $ yard config --gem-install-yri

See `yard config --help` for more information on RubyGems install hooks.

You can also add the following to your .gemspec to have YARD document your gem
on install:

    spec.metadata["yard.run"] = "yri" # use "yard" to build full HTML docs.

--------------------------------------------------------------------------------

問題ないか確認

  • 検証環境で問題ないか
  • テストが落ちてないか
  • 本番環境リリース後に問題ないか
