问题:

为什么我会收到错误:

无法创建“闭包类型”类型的常量值。 在此上下文中仅支持基本类型(例如Int32,String和Guid)。

当我尝试枚举以下Linq查询?

IEnumerable<string> searchList = GetSearchList();
using (HREntities entities = new HREntities())
{
   var myList = from person in entities.vSearchPeople
   where upperSearchList.All( (person.FirstName + person.LastName) .Contains).ToList();
}

更新 :如果我尝试以下尝试隔离问题,我得到相同的错误:

where upperSearchList.All(arg => arg == arg) 

所以看起来问题出在All方法上,对吧? 有什么建议?

Why do I get the error:Unable to create a constant value of type ‘Closure type’.Only primitive types (for instance Int32, String and Guid) are supported in this context.When I try to enumerate the following Linq query?Update : If I try the following just to try to isolate the problem, I get the same error:So it looks like the problem is with the All method, right?Any suggestions?

问题:

我最近通过pear安装程序在我的服务器上安装了phpunit。

当我去运行测试时,我收到以下错误:

PHP警告:require_once(PHPUnit / Util / Filter.php):无法打开流:第44行/ usr / bin / phpunit中没有此类文件或目录

PHP致命错误:require_once():在44行/ usr / bin / phpunit中打开所需的’PHPUnit / Util / Filter.php'(include_path =’。:/ usr / bin / php’)失败

在做了一些搜索之后,我尝试对服务器上的php.ini文件中的include_path进行一些修改。 但这没有做到。

知道可能导致这种情况的原因吗?

I recently installed phpunit on my server via the pear installer.When I go to run a test I get the following error:PHP Warning: require_once(PHPUnit/Util/Filter.php): failed to open stream: No such file or directory in /usr/bin/phpunit on line 44PHP Fatal error: require_once(): Failed opening required ‘PHPUnit/Util/Filter.php’ (include_path=’.:/usr/bin/php’) in /usr/bin/phpunit on line 44After doing some searching, I tried making some modifications to the include_path in my php.ini file on the server.But that hasn’t done a thing.Any idea what might be causing this?

问题:

我在Google Chrome开发者工具中收到此错误:

找不到jquery-2.0.2.min.map

我通过从jquery-2.0.2.min.js删除这一行找到了摆脱它jquery-2.0.2.min.js :

//@ sourceMappingURL=jquery-2.0.2.min.map

但是,我不相信这是一个好主意,因为这可能只是一个临时修复,可能会成为未来的问题。 因为我不太了解这个错误的性质和愚蠢的解决方案:是什么导致了这个错误并且有更好的解决方案吗?

显然,这不仅仅是与jQuery 2.0.2相关的问题。 一个非常相似的Stack Overflow问题有一个很好的解释是jQuery的jquery-1.10.2.min.map触发了404(Not Found) 我希望这会对局势有所了解。

I’m getting this error in Google Chrome developer tools:jquery-2.0.2.min.map not foundI found a way to get rid of it by removing this line from my jquery-2.0.2.min.js :However, I don’t believe this was a good idea, since this may be just a temporary fix that may be a problem in the future.Since I don’t really understand the nature of this error and the goofy solution: what’s causing this error and is there a better fix for it?Apparently, this is not a question related to jQuery 2.0.2 only.A very similar Stack Overflow question with a great explanation is jQuery’s jquery-1.10.2.min.map is triggering a 404 (Not Found) .I hope this will shed some light on the situation.

问题:

在一个使用Androidx:appcompat:appcompat:1.0.0-rc01新建的项目中,

java.lang.ClassNotFoundException: Didn't find class 
"android.view.View$OnUnhandledKeyEventListener" on path: DexPathList

我还添加了configuration.all

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == "androidx.appcompat") {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion "1.+"
            }
        }
    }
}

这不影响应用程序功能或崩溃。 但是在应用程序运行时始终会出现此错误。 请帮助我解决错误。 整个堆栈跟踪如下。

In a newly created project with Androidx:appcompat:appcompat:1.0.0-rc01, I’m getting theI had also added configuration.allThis one is not affecting the app functionality or crashes.But it always have this error when the app is running.Kindly help me to solve the error.The entire stack trace is as follows.

问题:

我想在我的JSF页面中使用非中断空格。 我知道,用简单的HTML我可以使用&nbsp; 为此,这工作正常。 但是,当我把那些&nbsp; 在Facelets页面中,它的错误如下:

错误解析/page.xhtml:错误跟踪[第42行]引用了实体“nbsp”,但未声明。

这是怎么造成的,我该如何解决?

I’d like to use non breaking spaces in my JSF page.I know, in plain HTML I could use &nbsp;for this and this works fine.However, when I put those &nbsp;in a Facelets page, then it errors as follows:Error Parsing /page.xhtml: Error Traced[line: 42] The entity “nbsp” was referenced, but not declared.How is this caused and how can I solve it?
