class - 错误: Compile Error: sObject type 'KnowledgeArticleVersion' is not supported.

Question

我在看起来不再存在的对象上遇到错误。尝试将不相关的Apex触发器部署到生产环境时，由于此错误，它不会让我失望。有人看过吗？您有什么建议吗？

码

public with sharing class KnowledgeArticleViewerController {
    public KnowledgeArticleVersion article {get; set;}
    private Id articleId;

    public KnowledgeArticleViewerController(ApexPages.standardController stdController) {
        articleId = ApexPages.currentPage().getParameters().get('id');

        List<KnowledgeArticleVersion> articles = [SELECT Id,Title FROM KnowledgeArticleVersion WHERE PublishStatus = 'Online'];

        ApexPages.addMessage( new ApexPages.Message(ApexPages.Severity.ERROR, 'Got article ids: ' + articles.get(0).Id 
         + ' ' + articles.get(1).Id + ' ' + articles.get(2).Id) );

        article = articles.get(0);

    }
}

结束码

Error: Compile Error: sObject type 'KnowledgeArticleVersion' is not supported. If you are attempting to use a custom object, be sure to append the '__c' after the entity name. Please reference your WSDL or the describe call for the appropriate names. at line 8 column 44

没有 KnowledgeArticleVersion对象，并且在我到达这里之前2年以上实现了此代码。

每当您将任何代码更改部署到Salesforce的生产实例时，都会重新编译该实例的所有代码并运行所有测试。

您将必须通过删除对不存在的sObject(KnowledgeArticleVersion)的引用来修复此代码，然后才可以部署其他更改。
