delphi - Delphi 2009重构错误

天真地看着那个callstack，你有没有检查过编译器选项中与调试符号相关的所有内容是否？
这是错误消息，因为屏幕截图托管网站存在一些问题。
See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
好的发现了这个案子。
仅当我们执行重构的文件不在DPR文件的USES部分中时才会发生此错误。是Delphi搜索路径中的库文件（或者如何调用此路径）。
