我在大约十分之一的系统上使用 WiX 进行重大升级时发现间歇性问题。 Windows 服务在卸载旧版本产品时被删除，然后在安装新版本产品时安装并启动。但是 1 或 2 秒后，新版本的 Windows 服务被卸载。我认为这可能违反了组件规则或文件版本控制规则，例如 this question ，但我没有在 WiX 脚本中看到问题。我没有更改组件 GUID 或引用其他组件中的资源，Windows 服务 exe 将从版本 1.4.3 升级到 1.4.7。
升级失败后，我可以卸载新版产品，安装老版产品，然后大升级到新版产品，没有任何问题。在第一次初始升级失败后，所有其他升级都可以工作。任何帮助将不胜感激。

最佳答案
根据日志和 RemoveExistingProducts 文档。当您的升级发生在 afterInstallExecute 时，实际的事件顺序是首先安装新版本，然后卸载旧产品。
在 12:08:59 停止旧服务(从升级安装)，然后删除旧服务。 然后安装新服务，并在 12:09:03.222 启动，服务配置操作也在那里进行。 在 12:09:04.535 RemoveExistingProducts 运行，卸载旧产品。那个uninstall在12:09:04:832有一个ServiceControl来停止服务(你刚刚安装的那个)，因为你的ServiceControl有stop=both，也就是说它会在卸载的时候停止它，这个是旧版本的uninstall产品。
由于这是静态定义的行为，也许对可变行为最可能的解释是计时赛跑。例如，您新安装的服务可能还没有准备好接受大多数安装中的停止请求，因此它不会在旧产品卸载时停止。但是有时它确实会响应并关闭。
然而，撇开理论不谈，底线仍然是您拥有带有 ServiceControl stop=both 的代码，并且卸载带有 stop 的旧产品是最后发生的事情(请注意，您仅在安装时开始，不是卸载!)。您可能需要更改升级顺序，因为 stop=both 在较旧的已安装产品中，例如，如果不使用补丁更改它就无法修复。您的升级 afterInstallInitialize 应该没问题，因为安装实际上是在卸载旧产品之后进行的。

我正在尝试使用ruby和Savon来使用网络服务。测试服务为http://www.webservicex.net/WS/WSDetails.aspx?WSID=9&CATID=2require'rubygems'require'savon'client=Savon::Client.new"http://www.webservicex.net/stockquote.asmx?WSDL"client.get_quotedo|soap|soap.body={:symbol=>"AAPL"}end返回SOAP异常。检查soap信封，在我看来soap请求没有正确的命名空间。任何人都可以建议我
我需要在客户计算机上运行Ruby应用程序。通常需要几天才能完成(复制大备份文件)。问题是如果启用sleep，它会中断应用程序。否则，计算机将持续运行数周，直到我下次访问为止。有什么方法可以防止执行期间休眠并让Windows在执行后休眠吗？欢迎任何疯狂的想法;-) 最佳答案 Here建议使用SetThreadExecutionStateWinAPI函数，使应用程序能够通知系统它正在使用中，从而防止系统在应用程序运行时进入休眠状态或关闭显示。像这样的东西:require'Win32API'ES_AWAYMODE_REQUIRED=0x0
我想安装一个带有一些身份验证的私有(private)Rubygem服务器。我希望能够使用公共(public)Ubuntu服务器托管内部gem。我读到了http://docs.rubygems.org/read/chapter/18.但是那个没有身份验证-如我所见。然后我读到了https://github.com/cwninja/geminabox.但是当我使用基本身份验证(他们在他们的Wiki中有)时，它会提示从我的服务器获取源。所以。如何制作带有身份验证的私有(private)Rubygem服务器？这是不可能的吗？谢谢。编辑:Geminabox问题。我尝试“捆绑”以安装新的gem..

我有一个对象has_many应呈现为xml的子对象。这不是问题。我的问题是我创建了一个Hash包含此数据，就像解析器需要它一样。但是rails自动将整个文件包含在.........我需要摆脱type="array"和我该如何处理？我没有在文档中找到任何内容。 最佳答案 我遇到了同样的问题；这是我的XML:我在用这个:entries.to_xml将散列数据转换为XML，但这会将条目的数据包装到中所以我修改了:entries.to_xml(root:"Contacts")但这仍然将转换后的XML包装在“联系人”中，将我的XML代码修改为
查看Ruby的CSV库的文档，我非常确定这是可能且简单的。我只需要使用Ruby删除CSV文件的前三列，但我没有成功运行它。 最佳答案 csv_table=CSV.read(file_path_in,:headers=>true)csv_table.delete("header_name")csv_table.to_csv#=>ThenewCSVinstringformat检查CSV::Table文档:http://ruby-doc.org/stdlib-1.9.2/libdoc/csv/rdoc/CSV/Table.html
我发现ActiveRecord::Base.transaction在复杂方法中非常有效。我想知道是否可以在如下事务中从AWSS3上传/删除文件:S3Object.transactiondo#writeintofiles#raiseanexceptionend引发异常后，每个操作都应在S3上回滚。S3Object这可能吗？？ 最佳答案 虽然S3API具有批量删除功能，但它不支持事务，因为每个删除操作都可以独立于其他操作成功/失败。该API不提供任何批量上传功能(通过PUT或POST)，因此每个上传操作都是通过一个独立的API调用完成的
我在我的Rails项目中使用Pow和powifygem。现在我尝试升级我的ruby版本(从1.9.3到2.0.0，我使用RVM)当我切换ruby版本、安装所有gem依赖项时，我通过运行railss并访问localhost:3000确保该应用程序正常运行以前，我通过使用pow访问http://my_app.dev来浏览我的应用程序。升级后，由于错误Bundler::RubyVersionMismatch:YourRubyversionis1.9.3,butyourGemfilespecified2.0.0，此url不起作用我尝试过的:重新创建pow应用程序重启pow服务器更新战俘

最近，当我启动我的Rails服务器时，我收到了一长串警告。虽然它不影响我的应用程序，但我想知道如何解决这些警告。我的估计是imagemagick以某种方式被调用了两次？当我在警告前后检查我的git日志时。我想知道如何解决这个问题。-bcrypt-ruby(3.1.2)-better_errors(1.0.1)+bcrypt(3.1.7)+bcrypt-ruby(3.1.5)-bcrypt(>=3.1.3)+better_errors(1.1.0)bcrypt和imagemagick有关系吗？/Users/rbchris/.rbenv/versions/2.0.0-p247/lib/ru
