在签名块中找到可执行脚本代码-PowerShell错误

Question

PowerShell脚本出现错误：

At line:365 char:17
+                 $HTMLerror += $usererror
+                 ~~~~~~~~~~~~~~~~~~~~~~~~
Executable script code found in signature block.

At line:367 char:17
+                 $ErrorMessage
+                 ~~~~~~~~~~~~~
Executable script code found in signature block.

At line:371 char:1
+ $content = "
+ ~~~~~~~~~~~~
Executable script code found in signature block.

At line:390 char:1
+ $table += $content
+ ~~~~~~~~~~~~~~~~~~
Executable script code found in signature block.

At line:394 char:5
+     $HTMLerror | Add-Content C:\test.html
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Executable script code found in signature block.

At line:396 char:5
+     $table | Add-Content C:\test.html
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Executable script code found in signature block.

At line:398 char:5
+     $endtable = "</table>"
+     ~~~~~~~~~~~~~~~~~~~~~~
Executable script code found in signature block.

At line:400 char:5
+     $endtable | Add-Content C:\test.html
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Executable script code found in signature block.

进行一些研究后，似乎是PowerShell中的一个错误。前364行代码可以正常工作，但是由于某种原因，此错误始于365行。有人发现过该错误的解决方法吗？

任何帮助或提示将不胜感激！ -leah_cyberpadawan
