Ruby on Railsエラー

Question

私は本当に助けが必要です。私はRubyの専門家ではなく、私のUbuntuサーバー上で実行する既存のRubyアプリケーションを取得しようとしています。

私は私がすべてを正しく行っていると思いますが、私は、次のエラーを取得し続ける：ここ

Warning! PATH is not properly set up, $GEM_HOME is not set, 
     usually this is caused by shell initialization files - check   
them for 'PATH=...' entries, 

と同様に

You are using '.rvmrc', it requires trusting, it is slower and it is  
not compatible with other ruby managers, 
you can switch to '.ruby-version' using 'rvm rvmrc to ruby-version' 

はRVM先から出力された：

rvm info 
Warning! PATH is not properly set up, $GEM_HOME is not set, 
usually this is caused by shell initialization files - check  
them for 'PATH=...' entries, it might also help to re-add RVM 
to your dotfiles: 'rvm get stable --auto-dotfiles',to fix 
temporarily in this shell session run: 'rvm use ruby-2.2.1'.

感謝!!!!

UPDATE

おかげで、私が使用してGEM_HOMEとGEM_PATH値を設定することができた。しかし、私は、フォルダを変更し、戻ったときに、私はエラーを取得します（下記参照）

export GEM_HOME=/usr/local/rvm/gems/ruby-2.2.1 
export GEM_PATH=/usr/local/rvm/gems/ruby-2.2.1:/usr/local/rvm/gems/ruby-2.2.1@global 
echo "source $HOME/.rvm/scripts/rvm" >> ~/.bash_profile 

をし、変数はもはや設定されません。

You are using '.rvmrc', it requires trusting, it is slower and it is not compatible with other ruby managers, 
you can switch to '.ruby-version' using 'rvm rvmrc to ruby-version' 
or ignore this warning with 'rvm rvmrc warning ignore /var/www/XXXXX/MicoBackup/.rvmrc', 
'.rvmrc' will continue to be the default project file in RVM 1 and RVM 2, 
to ignore the warning for all files run 'rvm rvmrc warning ignore all.rvmrcs'. 

Gemset 'XXXXXX' does not exist, 'rvm ree-1.8.7-2012.02 do rvm gemset create XXXXXX' first, or append '--create'.

の重複のように見える：エラーメッセージは、あなたのPATHにGEM_HOMEを逃している、示したようhttps://unix.stackexchange.com/questions/203376/how-to-set-ruby-gem-home-and-gem-path

。確かRVMを行うことにより

スタートが正しく.bash_profileに供給される。

echo "source $HOME/.rvm/scripts/rvm" >> ~/.bash_profile 

問題が解決しない場合は、手動GEM_HOMEを設定してみてくださいすることができます。上記の提供されたリンクを参照してください。
