我无法开始使用rails 3.0.0,因为它只是不加载rake任务
耙宝石：安装
rake aborted! Don't kNow how to build task 'gems:install'
耙-T
rake about # List versions of all Rails frameworks and the environment rake db:create # Create the database from config/database.yml for the current Rails.env (use db:create:all to create all dbs in the config) rake db:drop # Drops the database for the current Rails.env (use db:drop:all to drop all databases) rake db:fixtures:load # Load fixtures into the current environment's database. rake db:migrate # Migrate the database (options: VERSION=x,VERBOSE=false). rake db:migrate:status # display status of migrations rake db:rollback # Rolls the schema back to the prevIoUs version (specify steps w/ STEP=n). rake db:schema:dump # Create a db/schema.rb file that can be portably used against any DB supported by AR rake db:schema:load # Load a schema.rb file into the database rake db:seed # Load the seed data from db/seeds.rb rake db:setup # Create the database,load the schema,and initialize with the seed data (use db:reset to also drop the db first) rake db:structure:dump # Dump the database structure to an sql file rake db:version # Retrieves the current schema version number rake doc:app # Generate docs for the app -- also availble doc:rails,doc:guides,doc:plugins (options: TEMPLATE=/rdoc-template.rb,TITLE="Custom Title") rake log:clear # Truncates all *.log files in log/ to zero bytes rake middleware # Prints out your Rack middleware stack rake notes # Enumerate all annotations (use notes:optimize,:fixme,:todo for focus) rake notes:custom # Enumerate a custom annotation,specify with ANNOTATION=CUSTOM rake rails:template # Applies the template supplied by LOCATION=/path/to/template rake rails:update # Update both configs and public/javascripts from Rails (or use just update:javascripts or update:configs) rake routes # Print out all defined routes in match order,with names. rake secret # Generate a crytographically secure secret key (this is typically used to generate a secret for cookie sessions). rake stats # Report code statistics (KLOCs,etc) from the application rake test # Runs test:units,test:functionals,test:integration together (also available: test:benchmark,test:profile,test:plugins) rake test:recent # Run tests for recenttest:prepare / Test recent changes rake test:uncommitted # Run tests for uncommittedtest:prepare / Test changes since last checkin (only Subversion and Git) rake time:zones:all # displays all time zones,also available: time:zones:us,time:zones:local -- filter with OFFSET parameter,e.g.,OFFSET=-6 rake tmp:clear # Clear session,cache,and socket files from tmp/ (narrow w/ tmp:sessions:clear,tmp:cache:clear,tmp:sockets:clear) rake tmp:create # Creates tmp directories for sessions,sockets,and pids
所以问题是,没有包含宝石任务.
这可能也是原因,我无法安装指南针.它给了我以下错误：
rails new testproj -m http://compass-style.org/rails/installer
rake gems:install GEM=haml --trace rake aborted! Don't kNow how to build task 'gems:install'
打包机在我的系统上坏了吗？我在雪豹上.
解决方法
你必须使用bundler,而不是rake任务.
尝试：
捆绑安装
尝试：
捆绑安装
如果要安装gem,则必须将它们放在Gemfile中(在项目根目录中),然后使用bundler安装它们. http://github.com/schacon/bundler
在你的Gemfile中：
gem "haml"
然后运行
bundle install
