我正在开发我的第一个Rails引擎.这是一个包含资产和基本功能的管理面板布局.
我真正想要的是它基于Twitter Bootstrap + SASS.
如果我在我的引擎的gemspec文件中只有这些行:
gem.add_dependency "railties", "~> 3.2"
gem.add_dependency "sass-rails"
gem.add_dependency "bootstrap-sass"
尝试访问页面时出现此错误:
ActionView::Template::Error (couldn't find file 'bootstrap'
(in /Users/swamiatma/Documents/Dropbox/coding/ruby/gems/tkh_admin_panel/app/assets/javascripts/admin.js:9)):
但是,如果我将其添加到主机应用程序gemfile:
gem 'bootstrap-sass'
所以我得到以下几行:
group :assets do
gem 'jquery-rails'
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'uglifier', '>= 1.0.3'
gem 'bootstrap-sass'
end
它现在工作正常.我认为这个依赖项严格属于Rails引擎gem,应该就在那里.
是什么赋予了？
的Gemfile:
source "http://rubygems.org"
gem "nokogiri", :git => "git://github.com/tenderlove/nokogiri.git"
运行时bundle,会发生以下错误:
Fetching git://github.com/tenderlove/nokogiri.git
Unfortunately, a fatal error has occurred. Please see the Bundler troubleshooting documentation at http://bit.ly/bundler-issues. Thanks!
C:/Ruby193/lib/ruby/gems/1.9.1/gems/bundler-1.1.4/lib/bundler/source.rb:592:in ``': No such file or directory - git clone "git://github.com/tenderlove/nokogiri.git" "C:/Ruby193/lib/ruby/gems/1.9.1/cache/bundler/git/nokogiri-d4bf05cb9e65f144f074351e5ebe3a0e44c00952" --bare --no-hardlinks (Errno::ENOENT)
我该如何解决？
它不仅可以与这颗宝石重现,还可以与其他宝石重现:黄瓜,水豚
我用的是Windows.
我在gemspecs中看到了很多这样的东西:
s.add_dependency 'some_gem', '~> 1.5.0'
什么〜>是什么意思？
在我的ruby脚本中,我需要gmail gem:
require 'rubygems'
require 'gmail'
在shell中运行时,它运行正常:
ruby my-script.rb
当我把它放在一个cron作业时,它无法执行:
* * * * * cd /to/script/directory;/usr/local/rvm/rubies/ree-1.8.7-2011.03/bin/ruby ./my-script.rb
日志显示无法加载gmail gem:
/usr/local/rvm/rubies/ree-1.8.7-2011.03/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require': no such file to load -- gmail (LoadError)
好吧,当我这样做时(把cmd放在bash -l -c'CMD'中):
* * * * * /bin/bash -l -c 'cd /to/script/directory;/usr/local/rvm/rubies/ree-1.8.7-2011.03/bin/ruby ./my-script.rb'
它再次正常工作.
为什么？
ps.I知道arg -l使bash成为登录shell,但这有什么区别？
我有一个名为"Backend"的Rails 3.2引擎(可安装).
Ruby平台是JRuby 1.7.0(1.9.3p203).
我还有一个Rails 3.2应用程序(称为my_app),其中Gemfile包含:
gem 'backend', :path => "/home/jacob/projects/backend"
我在my_app的根目录下执行"bundle install"并收到以下错误:
"无法在/ home/jacob/projects/backend的源代码中找到gem'backend(> = 0)java'.源代码不包含任何版本的'backend(> = 0)java'"
backend.gemspec:
$:.push File.expand_path("../lib", \__FILE__)
require "backend/version"
Gem::Specification.new do |s|
s.name = "Backend"
s.version = Backend::VERSION
s.authors = [""]
s.email = [""]
s.homepage = ""
s.summary = ""
s.description = ""
s.files = Dir["{app,config,db,lib}/\**/*"] + ["MIT-LICENSE", "Rakefile", "README.rdoc"]
s.test_files = Dir["test/**/*"]
end
有没有办法安装宝石,bundle install因此它们不会安装在ruby文件夹中,而是安装在项目的文件夹中？(我会在上面使用.gitignore)
有没有办法只为一些宝石做这个？
我正在尝试在Debian 6上做一个gem install therubyracer.我在1.9.3上使用rbenv.当我最初这样做时,它抱怨了libv8,所以我做了一个gem install libv8.现在,当我运行gem install therubyracer时,我收到以下错误,说它无法找到该文件.它正在讨论的文件是/home/chop/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/libv8-3.11.8.3-x86_64-linux/vendor/v8/out/然而,x64.release/obj.target/tools/gyp/libv8_base.a确实存在.

有这么好的宝石吗？
我不打算独自制作.

嗨,我在运行bundle install时收到消息,下面是我的gemsfile
source 'https://rubygems.org'
gem 'rails', '3.2.6'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
gem 'carrierwave'
gem 'rmagick v 2.13.1'
# 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' …此查询引发错误:
EncodingPreset.where('default = ?', false)
ActiveRecord::StatementInvalid: PG::Error: ERROR: syntax error at or near "default"
LINE 1: ...coding_presets".* FROM "encoding_presets" WHERE (default = ...
^
: SELECT "encoding_presets".* FROM "encoding_presets" WHERE (default = 'f')
但这有效:
EncodingPreset.where(:default => false)
为什么第一个查询不起作用？
