Ruby on rails 在 Ubuntu 上安装错误 [英] Ruby on rails installing error on Ubuntu

问题描述

我只是尝试通过以下命令安装 rails:

sudo gem install rails

但是出现这样的错误:

构建原生扩展.这可能需要一段时间...错误:安装导轨时出错:错误:无法构建 gem 本机扩展.

<代码>/usr/bin/ruby1.9.1 extconf.rb/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in 'require'来自 extconf.rb:1:in '

'

Gem 文件将重新安装在/var/lib/gems/1.9.1/gems/json-1.8.3 中以供检查.结果记录到/var/lib/gems/json-1.8.3/ext/json/ext/generator/gem_make.out

我试过几次重新安装 ruby​​ 也试过sudo apt-get update

我该怎么办?

解决方案

只需按照以下步骤操作，您就可以在 ubuntu 上轻松安装 rails :

首先使用command安装rvm(我猜你已经安装了):

$ \curl -L https://get.rvm.io |bash -s 稳定 --ruby

然后安装 Ruby :

$ rvm install ruby$ rvm --默认使用ruby-2.2.3

然后为 Rails 安装 Node.js:

$ sudo apt-get install nodejs

最后，通过以下方式安装导轨:

$ >宝石安装导轨

您可以使用以下命令检查安装的 rails 版本:

$ >导轨 -v

我希望这会有所帮助.

更新:

根据 @Amit 先生的评论，我们可以使用以下命令安装 ruby​​ 和 rails 组合为:

\curl -sSL https://get.rvm.io |bash -s 稳定 --rails

I just tried to install rails by this command:

sudo gem install rails

but error occurs like this:

Building native extensions. This could take a while... ERROR: Error installing rails: ERROR: Failed to build gem native extension.

/usr/bin/ruby1.9.1 extconf.rb /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in 'require' from extconf.rb:1:in '<main>'

Gem files will reamin installed in /var/lib/gems/1.9.1/gems/json-1.8.3 for inspection. Results logged to /var/lib/gems/json-1.8.3/ext/json/ext/generator/gem_make.out

I tried several times reinstalling ruby and also triedsudo apt-get update

What should I do?

解决方案

Just follow the below steps and you will be able to install rails easily on ubuntu :

First install rvm (I guess you have already installed) using the command :

$ \curl -L https://get.rvm.io | bash -s stable --ruby

Then install Ruby :

$ rvm install ruby
$ rvm --default use ruby-2.2.3

Then install Node.js for rails :

$ sudo apt-get install nodejs

And lastly , install rails by :

$ > gem install rails

You can check the version of rails installed using :

$ > rails -v 

I hope this helps.

Update:

As per @Amit sir's comment , We can use the below command which installs both , ruby and rails combined as :

\curl -sSL https://get.rvm.io | bash -s stable --rails
