我使用Rails 3.0.20和ruby 1.8.7(2011-06-30 patchlevel 352)

请建议我生成guid的最佳插件.

我正在设计一个状态页面,我需要显示延迟的作业是否正在运行.请帮我一个在代码中找到它的方法.

我使用的是Rails 3.0.20,ruby 1.8.7(2011-06-30 patchlevel 352)和delayed_job 3.0.4

我想在我的gerrit服务器上安装delete-project插件.根据最新版本,我应该从google源代码克隆它并使用buck build.

我克隆了它,我的降压也准备好了.

构建删除项目插件并将其添加到我的gerrit服务器时需要遵循的步骤是什么.

我试过了

buck build .

在克隆的删除项目源.但是,我收到以下错误

Traceback (most recent call last):
  File "/home/gerrit/buck/src/com/facebook/buck/parser/buck.py", line 872, in <module>
    main()

请帮忙

我正在尝试使用gradle构建一个简单的'hello world'安卓应用程序.如果我发出命令它会建立好

sudo ./gradlew build - >构建正常

但没有sudo,

./gradlew build - >显示以下错误

FAILURE: Build failed with an exception.

我使用以下两个命令在我的应用程序中运行测试：

ruby -Ilib test/unit/account_test.rb
ruby -Itest test/unit/account_test.rb

两者都工作正常。但是，有什么区别呢。这面旗帜到底-I意味着什么？

请注意以下事项:

"abcd#fg"  # => "abcd#fg"
"abcd#$fg" # => "abcd"    characters #$ and after them are skipped
"abcd#@fg" # => "abcd"    characters #@ and after them are skipped

它可以是字符串插值#而不是#{}.

$fg = 8
"abcd#$fg" # => "abcd8" 
@fg = 6
"abcd#@fg" # => "abcd6" 

它像插值一样工作.这是一个错误还是一个功能？
