gem命令(版本1.8.1,可能是1.8.0)在每次调用时都会发出一吨弃用通知.浏览警告屏幕以查看测试输出是痛苦的.

是否有一种隐藏弃用通知的简单方法？特别警告:

NOTE: Gem::Specification#default_executable= is deprecated with no replacement.

在主题中:他们是否相互竞争,重叠或相互补充？

谢谢,

这是干净安装的OSX 10.7 Lion.这是我采取的行动:

我安装了Xcode(4.1)

我安装了RVM(1.8.0):

bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)

$ echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile

我安装了ruby 1.8.7和1.9.2

rvm install 1.8.7
rvm install 1.9.2

我将开关切换到1.8.7

rvm use 1.8.7

我安装了一个宝石

gem install json

我在ruby文件中使用那个gem.

require 'json'

我尝试运行该ruby文件并收到以下错误:

main.rb.txt:1:in `require': no such file to load -- json (LoadError)

我仔细检查我的宝石:

gem list

..够了,它安装好了.

*** LOCAL GEMS ***

json (1.5.4)
rack (1.3.2)
rake (0.9.2 ruby)
sinatra (1.2.6)
tilt (1.3.3)

无论我需要什么样的宝石,这个问题都会出现.但是,如果我切换到1.9.2,一切正常.

我已经使用RVM卸载并重新安装了ruby 1.8.7(以及其他所有版本).我已经卸载并重新安装了宝石宝石.我错过了什么？

附加信息:宝石版本:1.8.6

我在哪里可以找到它？我正在运行OSX.

此外,我必须在旅行时离线做很多工作,所以如果有人可以提供可下载文档的任何提示,请告诉我.

如果我运行"Rails s"或"rails generate active_admin:install"或其他所有内容,我也会收到此错误...这是什么意思？

我已经运行"捆绑安装"或"捆绑更新".(RAILS 3.1.3)

不知怎的,我的rails安装成功隐藏了......

我有:

ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]
rvm 1.10.0-pre 
gem 1.8.10

我尝试安装rails:

sudo gem install rails

它工作正常:

Successfully installed rails-3.1.3
1 gem installed
Installing ri documentation for rails-3.1.3...
Installing RDoc documentation for rails-3.1.3...

当我做:

rails - v

我明白了

The program 'rails' is currently not installed.  You can install it by typing:
sudo apt-get install rails

而且,当我这样做

rake

在rails app根目录中,我得到:

Missing the Rails  gem. Please `gem install -v= rails`, update your 
RAILS_GEM_VERSION setting in config/environment.rb for the Rails version

我是Ruby on Rails的新手,现在尝试安装ROR.我按照这个教程http://blog.sudobits.com/2011/10/27/how-to-install-ruby-on-rails-in-ubuntu-11-10/

安装完成后,gem install rails创建我的项目就像rails new myproject.这里显示此消息

Your bundle is complete! Use捆绑秀[gemname] to see where a bundled gem is installed..

之后我运行bundle install它显示此错误Could not locate Gemfile.

请帮帮我怎样才能解决这个问题.

我正在使用以下Spreadsheet gem从ruby-on-rails生成excel表.http://spreadsheet.rubyforge.org/GUIDE_txt.html

我想格式化一个单元格,以便我可以看到它的顶部和底部边框,但不是任何其他边框.有没有人去过那里并且知道如何做？

http://spreadsheet.rubyforge.org/Spreadsheet/Format.html

- (Object)border =(boolean)激活或停用所有四个边框(左,右,上,下).

• 功能设置页面上的所有边框或没有边框.

我在Ubuntu 11.10上运行RubyMine 4,RubyMine中的每一件事情都很好,我可以运行服务器,开发等等.但是,当我需要在命令行上工作时,我什么都做不了..

我cd到我的app目录,然后我试着:

$ rails s

我明白了:

The program 'rails' is currently not installed.  You can install it by typing:
sudo apt-get install rails

这很奇怪,为什么我没有安装它,而我可以在RubyMine IDE中正常工作!

我需要使用命令行卸载gem,发现我不能使用命令行,因为它应该...

sam@ubuntu:~/Documents/RoR/course_builder$ gem uninstall 'capybara-firebug'
ERROR:  While executing gem ... (Gem::InstallError)
    cannot uninstall, check `gem list -d capybara-firebug`

$ gem list -d 会给我:

*** LOCAL GEMS ***

那里没有宝石..

如果我输入:

$ bundle install

我明白了:

/usr/lib/ruby/vendor_ruby/bundler/rubygems_ext.rb:8:in `require': no such file to load -- rubygems (LoadError)

我试图用roo gem解析XLS文件,而不使用文件上传插件.不幸的是我无法访问文件的数据.

我收到错误:

#<File:0x007ffac2282250> is not an Excel file

所以roo没有将文件识别为Excel文件.我是否需要在本地保存文件以使用roo,或者有办法解决这个问题.我想将excel文件的数据直接解析到数据库中.

通过的参数:

Parameters: {"utf8"=>"?", "authenticity_token"=>"yLqOpSK981tDNYjKSoWBh0VnFEKSk0XA/wOt3r+yWJc=", "uploadform"=>{"name"=>"xls", "file"=>#<ActionDispatch::Http::UploadedFile:0x007ffac22b6550 @original_filename="cities2.xls", @content_type="application/octet-stream", @headers="Content-Disposition: form-data; name=\"uploadform[file]\"; filename=\"cities2.xls\"\r\nContent-Type: application/octet-stream\r\n", @tempfile=#<File:/var/folders/qn/70msrkt90pd390sdr14_0g2m0000gn/T/RackMultipart20120306-3729-1m2xcsp>>}, "commit"=>"Save Uploadform"}

我正在尝试访问该文件

    if params[:uploadform][:file].original_filename =~ /.*\.xls$/i
        oo = Excel.new(params[:uploadform][:file].open)

        rooparse(oo)
    end

我也尝试了params [:uploadform] [:file] .read和params [:uploadform] [:file],但我认为.open将是正确的方法!？

你会建议在这里使用paperclip或carrierwave吗？

谢谢您的帮助!
