Ruby-on-rails 捆绑安装返回“找不到 Gemfile”

bundle install returns "Could not locate Gemfile"

提问by levelone

I'm new to Rails and am currently working through a guide. The guide states:

我是 Rails 的新手，目前正在阅读指南。该指南指出：

Use a text editor to update the Gemfile needed by Bundler with the contents of Listing 2.1.

source 'https://rubygems.org'

gem 'rails', '3.2.3'

group :development do
  gem 'sqlite3', '1.3.5'
end


# Gems used only for assets and not required
# in production environments by default.

group :assets do
  gem 'sass-rails',   '3.2.4'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.0'

group :production do
  gem 'pg', '0.12.2'
end

We then install and include the gems using the bundle installcommand:

    $ bundle install --without production 

If Bundler complains about no such file to load -- readline (LoadError)try adding gem 'rb-readline'to your Gemfile.)

使用文本编辑器将 Bundler 所需的 Gemfile 更新为清单 2.1 的内容。

source 'https://rubygems.org'

gem 'rails', '3.2.3'

group :development do
  gem 'sqlite3', '1.3.5'
end


# Gems used only for assets and not required
# in production environments by default.

group :assets do
  gem 'sass-rails',   '3.2.4'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.0'

group :production do
  gem 'pg', '0.12.2'
end

然后我们使用以下bundle install命令安装并包含 gem ：

    $ bundle install --without production 

如果 Bundler 抱怨no such file to load -- readline (LoadError)尝试添加gem 'rb-readline'到您的 Gemfile。）

I followed the steps even adding on gem 'rb-readline'to the Gemfile, but apparently the file can't be found and when I go to my text editor I do see the Gemfileitself. I noticed that they made me put gem 'rails', 3.2.3and my version of Rails is 3.2.1 so I tried changing it to 3.2.1 but that didn't work either.

我按照步骤甚至添加gem 'rb-readline'到Gemfile，但显然无法找到该文件，当我转到我的文本编辑器时，我确实看到了Gemfile它本身。我注意到他们让我放入了，gem 'rails', 3.2.3而我的 Rails 版本是 3.2.1，所以我尝试将其更改为 3.2.1，但这也不起作用。

Any thoughts or advice would be much appreciated.

任何想法或建议将不胜感激。

You just need to change directories to your app, THEN run bundle install:)

您只需要将目录更改为您的应用程序，然后运行bundle install:)

You may also indicate the path to the gemfile in the same command e.g.

你也可以在同一个命令中指明 gemfile 的路径，例如

BUNDLE_GEMFILE="MyProject/Gemfile.ios" bundle install

I had this problem as well on an OSX machine. I discovered that rails was not installed... which surprised me as I thought OSX always came with Rails. To install rails

• sudo gem install rails
• to install jekyll I also needed sudo
• sudo gem install jekyll bundler
• cd ~/Sites
• jekyll new <foldername>
• cd <foldername>ORcd !$(that is magic ;)
• bundle install
• bundle exec jekyll serve
• Then in your browser just go tohttp://127.0.0.1:4000/and it really should be running

• sudo gem install rails
• 安装 jekyll 我还需要 sudo
• sudo gem install jekyll bundler
• cd ~/Sites
• jekyll new <foldername>
• cd <foldername>或cd !$（这很神奇；）
• bundle install
• bundle exec jekyll serve
• 然后在你的浏览器中访问http://127.0.0.1:4000/它真的应该运行

1 make sure that the file is Gemfileinstead of gemfile.

1 确保文件Gemfile不是gemfile.

2 make sure you're in the same directory as the Gemfile.

2 确保您与Gemfile.

回答by Anant Agarwal

Search for the Gemfile file in your project, go to that directory and then run "bundle install". prior to running this command make sure you have installed the gem "sudo gem install bundler"

在您的项目中搜索 Gemfile 文件，转到该目录，然后运行“bundle install”。在运行此命令之前，请确保您已安装 gem“sudo gem install bundler”

Think more about what you are installing and navigate Gemfile folder, then try using sudo bundle install

多想想你正在安装什么并导航 Gemfile 文件夹，然后尝试使用 sudo bundle install
