Gemfile語法錯誤

Question

我得到以下錯誤：Gemfile語法錯誤。

這裏是我的代碼：

source 'https://rubygems.org' 

gem 'rails', '3.2.1' 

gem 'devise' 

# Bundle bootstrap gems 
group :development do 
    gem 'thin' 

    # Bundle edge Rails instead: 
    # gem 'rails', :git => 'git://github.com/rails/rails.git' 

    gem 'sqlite3' 


# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
    # gem 'therubyracer' 

    gem 'uglifier', '>= 1.0.3' 
end 

gem 'jquery-rails' 

# To use ActiveModel has_secure_password 
# gem 'bcrypt-ruby', '~> 3.0.0' 

# To use Jbuilder templates for JSON 
# gem 'jbuilder' 

# Use unicorn as the web server 
# gem 'unicorn' 

# Deploy with Capistrano 
# gem 'capistrano' 

# To use debugger 
# gem 'ruby-debug19', :require => 'ruby-debug' 

Answer 1

你錯過了end爲do在group :development。在gem 'sqlite3'後面添加一條end聲明。

你可以運行ruby -c Gemfile來檢查語法（它是普通的Ruby代碼），它會讓你知道錯誤在哪裏。

Answer 2

看起來你缺少development組後結束。

Answer 3

我多次遇到這個錯誤，但是我沒有碰到由rails生成的文件，並且ruby -c Gemfile說的語法是好的。在我的情況下，如果找不到rails命令，可能會報告Gemfile語法錯誤。

我使用brew + rbenv + ruby​​ 2.0 + rails 4，並使用以下命令恢復正常。

# new commands in brew-installed ruby might not be linked automatically 
brew unlink ruby && brew link ruby 
# fix "gem" itself 
sudo gem update --system 
# after installing executable with rbenv, you need rehash 
rbenv rehash
