Question

我正在使用Pyinstaller将Python编译为独立的可执行文件。源代码包括PySide和SqlAlchemy模块。 PyInstaller创建的dist .exe运行正常，但是当我运行访问数据库的命令时，我在命令提示符中得到了这个错误代码：

Traceback (most recent call last):

ImportError: Could not resolve module sqlalchemy.sql.default_comparator

编译时，命令提示符输出一些警告，说明无法找到与sql炼金术相关的“隐藏DLL”。它说它正在删除sqlalchemy / test文件作为回应。这里的任何帮助都将深表感谢。

Answer 1

我之前有同样的问题..通过在我的主程序上导入sqlalchemy.sql.default_comparator解决了这个问题..

Answer 2

正如@fredpi 所说，您可以将模块添加到您尝试编译的 python 文件的 .spec 文件中的 hiddenimports 初始值设定项的 Analysis 参数中。像这样：hiddenimports=['sqlalchemy.sql.default_comparator']

确保在运行 pyinstaller 时运行传递 .spec 文件，否则它会覆盖 .spec 文件并且您的更改将丢失。例如：pyinstaller.exe --onefile myscript.spec

Pyinstaller缺少SqlAlchemy dll
