Nitrous.io で One Month Rails のチュートリアルを行っていました。ある時点で、いくつかの奇妙なファイルがツリーに表示され、それらを削除しました。すべてが機能しなくなりました。

私は走った：

$ git add .
$ git checkout -f

そして木を復活させました。

しかし、私が走ったとき：

$ rails server

私は得る：

action@first-project-48185:~/pinteresting$ rails server                                                                                                        
-bash: rails: command not found

私も試しました：

$ ruby -v #and got an older version, so I reinstalled it
$ rails -v

action@first-project-48185:~/pinteresting$ rails -v                                                                                                            
-bash: rails: command not found

私が実行すると：

$ ruby -v #on MAC terminal, I get the correct version
$ rails -v #on MAC terminal, I get the correct version

興味深いことに、実行すると:

$ rails server or $ rails server -p 4000

私は得る：

イライラするのは、エラーやバグなしで最大の連続記録を達成したことです:(

これらのエラーで Rails が機能しなくなった理由はわかりませんが、Rails を再インストールすることをお勧めします。次のコマンドを実行して、Rails を再インストールします。

gem install rails

ここから、 を実行できるはずですrails server。

インストールが必要な他の gem が含まれているbundle install場合は、プロジェクト ディレクトリ内で実行することもできます。Gemfile
