在PyQt应用中处理丢失的软件包或DLL

Question

What's a good way to handle fatal errors - missing packages, .ui files not compiled, Qt DLLs or shared objects not found, etc. - in a PyQt app (or other Python app)?

Displaying a cross-platform message box without Qt DLLs or shared objects seems like a lot of work. Dumping a message to the console seems not very helpful, since the end user will likely not see the console. How do other Python apps handle this? Or do they simply assume that a properly installed app won't run into these problems?

distutils模型可以正确安装python应用程序，或者有一个第三方setuptools软件包，对于最终用户来说更容易。
