Question

我试图在单目录模式下使用 PyInstaller 来冻结我的 Python 程序（在这种情况下，是一个精简的示例）。生成的可执行文件可在我的计算机上运行，但在任何其他计算机上都无法运行。我打开了控制台（窗口），但没有出现任何消息。我尝试从命令提示符运行 exe 文件，但同样没有错误消息。它似乎运行了程序的一部分（我尝试输入“打印”命令，它们出现在控制台中），但 GUI 没有出现，脚本刚刚结束。

我成功地冻结了一个示例 PySimpleGUI 脚本，所以我怀疑这与 mplwidget 和 PyQT 有关。

PyInstaller EXE 文件在其他计算机上不起作用 - 没有错误
