我遇到了一个奇怪的SSIS错误，服务器上的脚本组件不断失败，并显示错误-“找不到脚本的二进制代码。请打开脚本并确保其正确构建”。 该脚本在我的本地计算机上构建完全正常。除了打开脚本组件时获得的标准引用之外，脚本组件基本上还引用了3个其他DLL。这些dll是Microsoft.Hadoop.avro.dll，Newtonsoft.json.dll和Microsoft.Csharp。
我必须下载Microsoft.Hadoop.avro和Newtonsoft.json，甚至在本地和服务器上都已经向GAC注册。
我尝试过打开组件，重建它们，保存它们并部署它们。我在数据流上将DelayValidation设置为False。在参考部分中，我已将dll的“本地复制”设置为False。我通过显式放置GAC位置（即C：\ Windows \ Microsoft.Net \ Assembly \ GAC_MSIL）重新添加了引用。
这是脚本组件的示例代码

#region Help: Using Integration Services Connnection Managers
/* Some types of connection managers can be used in this script component. See the help topic
* "Working with Connection Managers Programatically" for details.
*
* To use a connection manager in this script, first ensure that the connection manager has
* been added to either the list of connection managers on the Connection Managers page of the
* script component editor. To add the connection manager, save this script, close this instance of
* Visual Studio, and add the Connection Manager to the list.
*
* If the component needs to hold a connection open while processing rows, override the
* AcquireConnections and ReleaseConnections methods.
*
* Example of using an ADO.Net connection manager to acquire a SqlConnection:
* object rawConnection = Connections.SalesDB.AcquireConnection(transaction);
* SqlConnection salesDBConn = (SqlConnection)rawConnection;
*
* Example of using a File connection manager to acquire a file path:
* object rawConnection = Connections.Prices_zip.AcquireConnection(transaction);
* string filePath = (string)rawConnection;
*
* Example of releasing a connection manager:
* Connections.SalesDB.ReleaseConnection(rawConnection);

基本上，此脚本组件充当目标并写入avro文件。
如前所述，一切都可以在我的本地计算机上进行。我什至尝试从服务器上的SSIS目录下载本地软件包，然后执行它，甚至可以正常工作（只是为了查看在部署过程中是否发生了更改或出现问题）。我不知所措解释这里缺少什么。顺便说一下，这是SSIS 2016，已部署到目录（项目部署模型），然后通过SQL Agent作业执行它。
脚本组件的目标框架是.Net 4.5。
有人想出解决办法吗？
如果需要更多信息，我将很乐意提供。
答案 0 :(得分：0)
因此，在这种情况下，我发现了问题。运行SQL作业步骤的代理帐户没有正确的访问权限。这就是它引发神秘错误的原因-“找不到脚本的二进制代码”。创建了代理帐户，成为本地管理员，并且可以正常工作。
