但是当我运行应用程序时，出现以下错误：
过程入口点... renderSynchronous @ QRenderAspectPrivate @ Qt3DRender ...不在动态链接库中... qt3dsceneeditor.dll
为什么会收到此错误？ windeployqt.exe是否应该检测并复制所有依赖项？
答案 0 :(得分：0)
该错误是由于版本不匹配引起的。我正在这样运行命令：
> C:\Qt\Qt5.11.2\5.11.2\msvc2017_64\bin\windeployqt.exe .\qt3dsceneeditor.dll
我的应用程序是用Qt 5.11.2构建的，但是由于某些原因，C:\Qt\Qt5.11.2\5.11.2\msvc2017_64\bin\windeployqt.exe可执行文件正在从Qt 5.9.4目录复制DLL！我重命名 Qt 5.9.4文件夹，然后再次运行命令，错误得到解决。
