Oh-my-zshをインストールした後もRailsにアクセスできない

Question

最近oh-my-zshを設定しましたが、私のコマンドラインでRailsにアクセスすることができません（zshとbashの両方が私にはありませんレールが取り付けられていて、取り付けが必要です）。 oh-my-zshをインストールする前に、私はすでにインストールしていて、過去にかなり広範囲に作業していました。

マイ.zshrc：

# If you come from bash you might have to change your $PATH. 
# export PATH=$HOME/bin:/usr/local/bin:$PATH 

# Path to your oh-my-zsh installation. 
export ZSH=/Users/Alex/.oh-my-zsh 

export PS1="\w \$(parse_git_branch)" 

# Set name of the theme to load. Optionally, if you set this to "random" 
# it'll load a random theme each time that oh-my-zsh is loaded. 
# See https://github.com/robbyrussell/oh-my-zsh/wiki/Themes 
ZSH_THEME="awesomepanda" 

# Imports nvm from bash profile 
export NVM_DIR="$HOME/.nvm" 
. "/usr/local/opt/nvm/nvm.sh" 

export RBENV_ROOT=/usr/local/var/rbenv 
export PATH="$HOME/.rbenv/bin:$PATH" 
eval "$(rbenv init -)" 

# Uncomment the following line to use case-sensitive completion. 
# CASE_SENSITIVE="true" 

# Uncomment the following line to use hyphen-insensitive completion. Case 
# sensitive completion must be off. _ and - will be interchangeable. 
# HYPHEN_INSENSITIVE="true" 

# Uncomment the following line to disable bi-weekly auto-update checks. 
# DISABLE_AUTO_UPDATE="true" 

# Uncomment the following line to change how often to auto-update (in days). 
# export UPDATE_ZSH_DAYS=13 

# Uncomment the following line to disable colors in ls. 
# DISABLE_LS_COLORS="true" 

# Uncomment the following line to disable auto-setting terminal title. 
# DISABLE_AUTO_TITLE="true" 

# Uncomment the following line to enable command auto-correction. 
# ENABLE_CORRECTION="true" 

# Uncomment the following line to display red dots whilst waiting for completion. 
# COMPLETION_WAITING_DOTS="true" 

# Uncomment the following line if you want to disable marking untracked files 
# under VCS as dirty. This makes repository status check for large repositories 
# much, much faster. 
# DISABLE_UNTRACKED_FILES_DIRTY="true" 

# Uncomment the following line if you want to change the command execution time 
# stamp shown in the history command output. 
# The optional three formats: "mm/dd/yyyy"|"dd.mm.yyyy"|"yyyy-mm-dd" 
# HIST_STAMPS="mm/dd/yyyy" 

# Would you like to use another custom folder than $ZSH/custom? 
# ZSH_CUSTOM=/path/to/new-custom-folder 

# Which plugins would you like to load? (plugins can be found in ~/.oh-my-zsh/plugins/*) 
# Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/ 
# Example format: plugins=(rails git textmate ruby lighthouse) 
# Add wisely, as too many plugins slow down shell startup. 
plugins=(git z h take) 

source $ZSH/oh-my-zsh.sh 

# User configuration 

# export MANPATH="/usr/local/man:$MANPATH" 

# You may need to manually set your language environment 
# export LANG=en_US.UTF-8 

# Preferred editor for local and remote sessions 
# if [[ -n $SSH_CONNECTION ]]; then 
# export EDITOR='vim' 
# else 
# export EDITOR='mvim' 
# fi 

# Compilation flags 
# export ARCHFLAGS="-arch x86_64" 

# ssh 
# export SSH_KEY_PATH="~/.ssh/rsa_id" 

# Set personal aliases, overriding those provided by oh-my-zsh libs, 
# plugins, and themes. Aliases can be placed here, though oh-my-zsh 
# users are encouraged to define aliases within the ZSH_CUSTOM folder. 
# For a full list of active aliases, run `alias`. 
# 
# Example aliases 
# alias zshconfig="mate ~/.zshrc" 
# alias ohmyzsh="mate ~/.oh-my-zsh" 
alias reload=". ~/.zshrc && echo 'ZSH config reloaded from ~/.zshrc'" 

と私の.bashrc：これらの構成を考えると

export NVM_DIR=~/.nvm 
source $(brew --prefix nvm)/nvm.sh 

# Git 
function parse_git_branch { 
    ref=$(git symbolic-ref HEAD 2> /dev/null) || return 
    echo "("${ref#refs/heads/}")" 
} 
export PS1="\[\033[1;32m\][\w]\[\033[1;33m\]\$(parse_git_branch)\[\033[0m\] " 
export EDITOR='atom --wait' 
export VISUAL='atom --wait' 

eval "$(hub alias -s)" 

if which rbenv > /dev/null; then 
eval "$(rbenv init -)" 
fi 

、なぜRailsは動作しなくなりましコマンドはありませんでしょうか？指示通りに私が行うと

Rails is not currently installed on this system. To get the latest version, simply type: 

    $ sudo gem install rails 

You can then rerun your "rails" command. 

とsudo gem install railsを実行します：

Error installing rails: 
    activesupport requires Ruby version >= 2.2.2. 

私はルビーを更新しようとしたアップデート

：私は試してみて、任意のレールのコマンドを実行したときにここで は、エラー・チェーンでありますrbenvを使っていましたが、これはRbenvを更新したように見えるので、単にレールを再インストールするという私の努力がこの壁に打ちのめされました。

.bashrcファイルがもう使用されていないため、rbenv初期化を.zshrcファイルに追加する必要があります。
