.zshrc配置文件语法错误

我的.zshrc文件中某处出现语法错误，但似乎找不到。

我收到此错误消息：

.zshrc:49: bad assignment

这是我的.zshrc文件：

# Path to your oh-my-zsh configuration.
ZSH=$HOME/.oh-my-zsh

# Set name of the theme to load.
# Look in ~/.oh-my-zsh/themes/
# Optionally, if you set this to "random", it'll load a random theme each
# time that oh-my-zsh is loaded.
ZSH_THEME="robbyrussell"

# Example aliases
alias zshconfig="mate ~/.zshrc"
# alias ohmyzsh="mate ~/.oh-my-zsh"

# Set to this to use case-sensitive completion
# CASE_SENSITIVE="true"

# Uncomment this to disable bi-weekly auto-update checks
# DISABLE_AUTO_UPDATE="true"

# Uncomment to change how often before auto-updates occur? (in days)
# export UPDATE_ZSH_DAYS=13

# Uncomment following line if you want to disable colors in ls
# DISABLE_LS_COLORS="true"

# Uncomment following line if you want to disable autosetting terminal title.
# DISABLE_AUTO_TITLE="true"

# Uncomment following line if you want to disable command autocorrection
# DISABLE_CORRECTION="true"

# Uncomment following line if you want red dots to be displayed while waiting for completion
# COMPLETION_WAITING_DOTS="true"

# Uncomment 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"

# 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)
plugins=(git)

source $ZSH/oh-my-zsh.sh

# Customize to your needs...

alias g2sites = "cd /Users/MYNAME/Dropbox/Development" #<< THIS IS THE LINE
alias g2work = "cd /Users/MYNAME/Dropbox/Development/Work"

questino的生产线是上述倒数第二个。我的错误可能来自该行之前的语法，但我找不到它。

看到我错了吗？
