创建新应用程序时,我遇到3.0.3之后的任何rails版本的问题,我希望你的意见。
首先,我从系统gem uninstall rails
中移除导轨并按照说明正确操作。然后我安装了最新版本的rails gem install rails
,一切顺利,我的系统上有rails 3.0.7。
当我尝试创建一个新应用时,我得到的是:
Usage:
rails new APP_PATH [options]
Options:
-J, [--skip-prototype] # Skip Prototype files
-T, [--skip-test-unit] # Skip Test::Unit files
-G, [--skip-git] # Skip Git ignores and keeps
-m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL)
[--dev] # Setup the application with Gemfile pointing to your Rails checkout
-b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL)
[--edge] # Setup the application with Gemfile pointing to Rails repository
[--skip-gemfile] # Don't create a Gemfile
-d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db)
# Default: sqlite3
-r, [--ruby=PATH] # Path to the Ruby binary of your choice
# Default: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
-O, [--skip-active-record] # Skip Active Record files
Runtime options:
-q, [--quiet] # Supress status output
-s, [--skip] # Skip files that already exist
-f, [--force] # Overwrite files that already exist
-p, [--pretend] # Run but do not make any changes
Rails options:
-v, [--version] # Show Rails version number and quit
-h, [--help] # Show this help message and quit
Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.
无法创建骨架,我不断获取该菜单。
如果我删除3.0.7并切换回3.0.3然后一切都很好,我确实得到了一个应用程序框架。如果我尝试3.0.4,同样的问题。
有什么想法吗?
答案 0 :(得分:2)
因为你们中的一些人证实了rails>完全没有问题。 3.0.3我通过运行来清理我的配置:
sudo gem clean
根据我的理解,它删除了系统中所有旧版本的宝石,因此我最终使用rails 3.0.7,现在我已成功创建新应用程序了!我可以回到我的项目,谢谢你的帮助:)。
