Python导入错误: DLL load failed: The specified module could not be found on fman build system (fbs)

Question

当我尝试使用 fman 构建系统 (fbs) 将 python 脚本转换为 EXE 时遇到错误。当我尝试在虚拟环境中的 cmd 中运行 Python 3.6 上的程序时，发生了此错误。

我正在使用 Python 3.6 和 pyinstaller 3.4。以下是我使用的库的列表。

altgraph (0.17)
cycler (0.10.0)
fbs (0.8.4)
future (0.18.2)
joblib (0.14.1)
kiwisolver (1.1.0)
macholib (1.14)
matplotlib (3.1.2)
numpy (1.18.1)
opencv-contrib-python (4.1.2.30)
opencv-python (4.1.2.30)
pefile (2019.4.18)
pip (9.0.1)
PyInstaller (3.4)
pyparsing (2.4.6)
PyQt5 (5.9.2)
python-dateutil (2.8.1)
pywin32-ctypes (0.2.0)
scikit-learn (0.22.1)
scipy (1.4.1)
setuptools (39.1.0)
sip (4.19.8)
six (1.14.0)
webcolors (1.10)

以下是我收到的错误:

使用 PyInstaller 3.4，可能无法正确加载 scipy 的某些动态库，因为它们的位置已更改为不同的目录，即在 site-packages/scipy/.libs 下

您需要编辑PyInstaller/hooks/hook-scipy.py文件，以便在site-packages/scipy/.libs下搜索库

可以找到修复方法 here 您可以从 github 获取最新文件

如果您的应用程序也依赖于 numpy 模块，您可能还需要编辑 PyInstaller/hooks/hook-numpy.py
