You've tried to invoke Spring when it's already loaded (i.e. the Spring constant is defined).

This is probably because you generated binstubs with Spring 1.0, and you now have a Spring version > 1.0 on your system. To solve this, upgrade your bundle to the latest Spring version and then run `bundle exec spring binstub --all` to regenerate your binstubs. This is a one-time step necessary to upgrade from 1.0 to 1.1.

試した内容として下記のように指定のあったbundle exec spring binstub --allを実行しました。

Beginning in Rails 4, Rails ships with a `rails` binstub at ./bin/rails that
should be used instead of the Bundler-generated `rails` binstub.

If you are seeing this message, your binstub at ./bin/rails was generated by
Bundler instead of Rails.

You might need to regenerate your `rails` binstub locally and add it to source
control:

 rails app:update:bin           # Bear in mind this generates other binstubs
                                # too that you may or may not want (like yarn)

If you already have Rails binstubs in source control, you might be
inadverently overwriting them during deployment by using bundle install
with the --binstubs option.

If your application was created prior to Rails 4, here's how to upgrade:

  bundle config --delete bin    # Turn off Bundler's stub generator
  rails app:update:bin          # Use the new Rails executables
  git add bin                   # Add bin/ to source control

You may need to remove bin/ from your .gitignore as well.

When you install a gem whose executable you want to use in your app,
generate it and add it to source control:

  bundle binstubs some-gem-name
  git add bin/new-executable

エラー文の内容理解を試みましたが理解できませんでした...

補足情報（FW/ツールのバージョンなど）

Ruby on Rails5
MacOS

Answer 1

自分の場合だけかもですがgem 'font-awesome-sass', '~> 5.2.0'を入れていたのですが、最新のバージョンに変えたら直りました。

Springのバージョンを上げろというエラー文ですが、エラー文通りの対処をしても自分も上手くいかなかったので、どうやら新しくインストールしたGemが何らかの形でSpringに干渉していたのではないかと。

Answer 2

bundle exec spring binstub --all

を実行して、binstub を更新せよと書いてますが、実行されましたでしょうか？

【エラーが変わったことを受けた追記です】

以下のいずれかを実施する必要がありそうです。

●　以下で binstub を作成しなおす。

rails app:update:bin

● アプリを Rails4 で作成したものであれば、以下の手順を実行

bundle config --delete bin
rails app:update:bin
git add bin

なお、じ後、実行可能な gem をインストールした際は、以下を実行するように書かれています。

bundle binstubs some-gem-name
git add bin/new-executable

some-gem-name bin/new-executable をインストールした gem の名前
bin/new-executable 新たにインストールされた実行可能ファイル

申し訳ありませんが、内容については、未検証です。

ご回答ありがとうございます。ご指摘のあった内容箇所の修正を行いましたが、エラーがより複雑になりエラー文の理解も難しい状態となってしまいました...本文は現在のエラーの状態に編集してあります。
