推荐答案

文件 Qt5Cored.dll 将存在于您的系统上，否则也无法在Qt Creator中使用.我认为只是Windows搜索让您失望.打开一个cmd提示符并执行 dir c:\ Qt5Cored.dll/s

The file Qt5Cored.dll will exist on your system, otherwise it would not work from Qt Creator either. I think it's just Windows search that lets you down. Open a cmd prompt and do a dir c:\Qt5Cored.dll /s

另一个要注意的是，这些 * d.dll 是调试DLL的，这意味着您正在分发应用程序的调试版本.您可能需要构建发行版本以供分发.(在这种情况下，您将需要 Qt5Core.dll )

Another note is that those *d.dll are debug DLL's, which means you are distributing a debug version of your application. You might want to build a release version for distribution instead. (In which case you'll need Qt5Core.dll)
