Inno Setup Testing安装程序退出代码

如何访问基于Inno Setup的安装程序的返回代码?

例如,this文档说如果"安装程序无法初始化"则退出代码将为1。在我的安装程序中,在某些情况下,代码会从False返回InitializeSetup()。我在命令提示符下运行带有/silent标志的安装程序。如果我echo %errorlevel%,我会得到0.

InitializeSetup()函数的相关代码部分:

function InitializeSetup(): Boolean;
var
  ResultCode: Integer;
begin
  { In silent mode, set Result to false so as to exit before wizard is }
  { launched in case setup cannot continue. }
  if WizardSilent() then
  begin
    { CompareVersion() logically returns the -1, 0 or 1 based on }
    { whether the version being installed is less than, equal to or greater }
    { than version already installed. Returns 0 is there is no existing }
    { installation. }
    ResultCode := CompareVersion();
    if ResultCode < 0 then
    begin
      Result := False;
      Exit;
    end;
  end;

  Result := True;
end;

从命令行,这是我正在运行和捕获返回值的方式:

C:\VersionCheck>myinstaller.exe /Silent

C:\VersionCheck>echo %errorlevel%
0

C:\VersionCheck>

我有什么遗失的吗?

您的测试无效。

从命令行执行GUI应用程序(安装程序)时,控制台不会等待程序完成。因此%errorlevel%不能包含应用程序(安装程序)的退出代码,因为它尚未完成。

在这种情况下,%errorlevel%反映了仅启动应用程序的错误(但不成功)。

另请注意,静音模式实际上对此没有影响。非静音模式的行为相同。

但是,如果将完全相同的命令添加到批处理文件(.bat),它将起作用。批处理文件等待应用程序完成。

C:\VersionCheck>test.bat

C:\VersionCheck>myinstaller.exe /Silent

C:\VersionCheck>echo 1
1
C:\VersionCheck>

test.bat包含两个命令:

myinstaller.exe /Silent
echo %errorlevel%
