Railsチュートリアル(1~3章)をやった時のエラー解消

Railsチュートリアルを１度コピペで行いました。
2週目はちゃんと入力してやってみようかと思います。
タイポが多いので、エラーがわんさか ﾜｰﾜｰ ヽ(ﾟ∀ﾟ)ﾉ ﾜｰﾜｰ ヽ(ﾟ∀ﾟ)ﾉ ﾜｰﾜｰ

今回やるバージョンは4.0です。
まずは１章から、、、って言ってもほとんどなかったですが。

$ git push -u origin master
Username for 'https://github.com': himajin315
Password for 'https://himajin315@github.com':
remote: Repository not found.
fatal: repository 'https://github.com/himain315/first_app.git/' not found

$ git remote add origin https://github.com/himajin315/first_app.git
fatal: remote origin already exists.

ユーザ名をミスった！！
renameもあるけど消そう。

$ git remote remove origin
$ git remote add origin git@github.com:himajin315/first_app.git

次に２章です。

$ bundle install --without production
Fetching gem metadata from https://rubygems.org/..........
Fetching additional metadata from https://rubygems.org/..
Resolving dependencies...
Bundler could not find compatible versions for gem "railties":
  In snapshot (Gemfile.lock):
    railties (4.0.4)

  In Gemfile:
    rails (= 4.0.2) ruby depends on
      railties (= 4.0.2) ruby

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

bundle update をやれということですね。

（省略）

secure_token の tokne_file は定義されてない。（いつものやつ）

【Before】
File.write(tokne_file,token)

【After】
File.write(token_file,token)

あー。すでにsample_appはあったんだった。
前に作った sample_app -> sample_app2 に変更。
新しく sample_app レポジトリを作成してからpushしましょう。

・・・

あれ？spec_helperがない！！！
過去のコマンドをよく見ると「rails generate rspec::install」ってやってた(*ﾉω・*)ﾃﾍ

$ rails generate rspec:install  
   identical  .rspec
   exist  spec
   identical  spec/spec_helper.rb

これで完璧。

$ bundle exec rspec spec/requests/static_pages_spec.rb

あれ・・・。
チュートリアルのエラーと違う。

【Before】
    visit '/static_page/home' 
【After】
    visit '/static_pages/home' 

「s」を忘れてました。

第３章ではタイポが多くて疲れました。。。
