关于Qt国际化的问题

我不知道如何使用Qt为python应用程序创建翻译文件。

现在我只想翻译代码中的几个词。

从…起 Qt Linguist page 我知道我需要使用一个。pro项目文件,该文件将由 pylupdate4 等

我试着跑步:

$ qmake -project myfile.py
$ pylupdate4 myfile.pro -ts file.ts

但结果是。无法读取pro文件 ( XML error: Parse error at line 1, column 1 [...] )

从这个 Tutorial

$ pylupdate4 myfile.py -ts file.ts

有没有人能告诉我哪里出了问题,我在浏览器中打开的15个标签帮不上忙。
