railsのサーバー起動でUsageが出る

【PC：MacBookPro2012(13-inch, Mid 2012)、MacOS Mojave 10.14.4】
【ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-darwin18]】
【Rails 5.2.3】
【mysql Ver 8.0.15 for osx10.14 on x86_64 (Homebrew)】


時間を置いてRailsのサーバーを起動させようとしたらできなかった。
その時の解決方法を記録する。

 サーバー起動に使用したのは以下のコマンド2つ。

```
$ bundle exec rails server
```
```
$ rails s
```
どちらのコマンドの応答も以下の通り。

```

Description:
    The 'rails new' command creates a new Rails application with a default
    directory structure and configuration at the path you specify.

    You can specify extra command-line arguments to be used every time
    'rails new' runs in the .railsrc configuration file in your home directory.

    Note that the arguments specified in the .railsrc file don't affect the
    defaults values shown above in this help message.

Example:
    rails new ~/Code/Ruby/weblog

    This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
```

試したこと(解決できなかった)

```
$ bundle exec rake rails:update:bin
rake aborted!
Don't know how to build task 'rails:update:bin' (See the list of available tasks with `rake --tasks`)
Did you mean?  app:update:bin
/Users/Owner/Desktop/rails_lesson/devise_sample3/vendor/bundle/gems/rake-12.3.3/exe/rake:27:in `<top (required)>'
/Users/Owner/.rbenv/versions/2.6.3/bin/bundle:23:in `load'
/Users/Owner/.rbenv/versions/2.6.3/bin/bundle:23:in `<main>'
(See full trace by running task with --trace)
```


【結果】解決方法
上の Did you mean?  app:update:bin のメッセージ通りにやってみた。

```
$ bundle exec rake app:update:bin
　　　 create  bin
      create  bin/bundle
      create  bin/rails
      create  bin/rake
      create  bin/setup
      create  bin/update
      create  bin/yarn
```

この後無事サーバー起動できました。
早く解決できて良かった。
