小编ekr*_*aca的帖子

如果需要,我正在尝试添加尾部斜杠:

a = '/var/www'
a.gsub
...

我不知道怎么做.

每当Rails生成器运行一个或多个选项时,最薄的提升OptionParse::InvalidOption.

我使用的是Rails 3.1,Ruby 1.9.2-p290和Mintest 2.10.0.

generate命令实际上将运行并处理传递的选项,但Minitest会在最后引发异常和堆栈跟踪:

rails generate model x --no-migration -s -p

  invoke  active_record     
  identical    app/models/x.rb 
  invoke test_unit 
  identical      test/unit/x_test.rb 
  identical     test/fixtures/xs.yml

  /Users/max/.rvm/gems/ruby-1.9.2-p290/gems/minitest-2.10.0/lib/minitest/unit.rb:900:in 'block in process_args': invalid option: --no-migration (OptionParser::InvalidOption)       
  from /Users/max/.rvm/gems/ruby-1.9.2-p290/gems/minitest-2.10.0/lib/minitest/unit.rb:879:in 'new'
  from /Users/max/.rvm/gems/ruby-1.9.2-p290/gems/minitest-2.10.0/lib/minitest/unit.rb:879:in 'process_args'
  from /Users/max/.rvm/gems/ruby-1.9.2-p290/gems/minitest-2.10.0/lib/minitest/unit.rb:929:in '_run'
  from /Users/max/.rvm/gems/ruby-1.9.2-p290/gems/minitest-2.10.0/lib/minitest/unit.rb:922:in 'run'  
  from /Users/max/.rvm/gems/ruby-1.9.2-p290/gems/minitest-2.10.0/lib/minitest/unit.rb:690:in 'block in autorun'

还有其他人遇到过这个吗？

我正在尝试将我的应用程序推送到Heroku,但是我得到了这个相当随意的错误:

Errno::ENOENT: No such file or directory @ rb_sysopen -\
       /tmp/build_.../config/aws.yml
       /tmp/build_.../vendor/bundle/ruby/2.1.0/gems/safe_yaml-1.0.3/lib/safe_yaml.rb:39:in `initialize'

       /tmp/build_.../vendor/

我在aws.yml文件中有正确的键,所以我不确定为什么我会收到此错误,也可以在本地正常工作.我已经尝试删除该/tmp文件夹并让Heroku重新生成它也无法正常工作.我该如何解决？

在Ubuntu 14.04上使用Capistrano部署Rails应用程序时,我收到以下错误:

fatal: destination path '/var/www/APP-NAME/repo' already exists and is not an empty directory.

我可以jruby-complete从传递给它的jar中消耗宝石.但我想使用一个中央宝石回购.

这就是我现在能做的:

$ java -jar jruby-complete-1.6.5.jar -S gem list

*** LOCAL GEMS ***

rake (0.8.7)
sources (0.0.1)


$ java -jar jruby-complete-1.6.5.jar -rjar_of_gems.jar -S gem list

*** LOCAL GEMS ***

erubis (2.7.0)
mizuno (0.4.1)
rack (1.4.0)
rack-protection (1.2.0)
rake (0.8.7)
rna (0.0.101)
sinatra (1.3.2)
sources (0.0.1)
tilt (1.3.3)

每次更新gem或者需要添加gem时都必须更改jar文件比我想做的更开销.

任何建议,必须有一种方法jruby-complete来指向像常规jruby宝石回购？

我已经安装或者我认为是在运行leopard 10.5.8的osx ppc上是如此新版本的ruby但是当我运行时ruby --version it shows the old one 1.8.7(默认在机器上)但是当我运行时...

find /usr -type f -name \*.rb

它显示ruby2.0.o打开:

/usr/local/lib/ruby/2.0.0/

包含所有.rb文件.

但是当我检查使用时 locate ruby

它显示了1.8.7版本

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

任何时候我检查ruby --version它显示1.8.7 ...我怎么能改变它？

完全是新手......谢谢.

BTW rvm不是通过anychance或自制软件安装的,我的xcode没有下载.

我正在使用letrate gem并收到以下错误:

ArgumentError - wrong number of arguments (3 for 2):

我试图将版本降级1.0.9为1.0.8,然后我将源复制到lib目录仍然我得到相同的错误.

我正在运行Spree 2.2.我正在尝试将标准分类法/过滤器列表显示在Spree的每个单独的产品页面上,但我找不到它在哪里决定是否要显示侧边栏内容.如果有人能够阐明决定在哪里/如何决定我会非常感激.

1. 我正在尝试复制pyLearn2文档中的教程示例.当我运行时python make_dataset.py,在示例中,我收到此错误:

   我可以matplotlib在命令行中导入和映像python.有人可以帮助我理解它抱怨什么以及如何解决错误？

2. 另一个问题(可能与上述问题有关,也可能与之无关)是链接错误

我mongo_mapper在Rails中使用MongoDB和gem,项目足够大.有什么办法可以将数据从Mongoid迁移到Postgresql吗？
