python - 使用pyinstaller冻结python代码时如何将lib_lightgbm.dll添加到exe中

Question

我正在创建一个导入 Microsoft LightGBM 的 python 代码的单文件可执行文件。我使用以下命令来创建 exe：

pyinstaller -F --hidden-import numpy.core._dtype_ctypes pro.py

创建exe并运行后，出现以下错误：

Exception: Cannot find lightgbm library file in following paths:
C:\Users\...\AppData\Local\Temp\_MEI61682\lightgbm\lib_lightgbm.dll
C:\Users\...\AppData\Local\Temp\lib_lightgbm.dll
C:\Users\...\AppData\Local\Temp\_MEI61682\lightgbm\compile\lib_lightgbm.dll
C:\Users\...\AppData\Local\Temp\_MEI61682\compile\lib_lightgbm.dll
C:\Users\...\AppData\Local\Temp\lib\lib_lightgbm.dll
C:\Users\...\AppData\Local\Temp\_MEI61682\compile\Release\lib_lightgbm.dll
C:\Users\...\AppData\Local\Temp\_MEI61682\compile\windows\x64\DLL\lib_lightgbm.dll
C:\Users\...\AppData\Local\Temp\Release\lib_lightgbm.dll
C:\Users\...\AppData\Local\Temp\windows\x64\DLL\lib_lightgbm.dll
[6352] Failed to execute script pro

我尝试lib_lightgbm.dll使用选项添加：

--add-data lib_lightgbm.dll;\compile

这解决了安装 lightgbm 的机器上的错误，但在其他机器上，它给出了以下错误：

Traceback (most recent call last):
  File "site-packages\PyInstaller\loader\pyiboot01_bootstrap.py", line 149, in __init__
  File "ctypes\__init__.py", line 348, in __init__

During handling of the above exception, another exception occurred:

谁能帮我解决这个问题？
