PyInstaller“无法执行脚本”错误

Question

I'm trying to make an exe file with PyInstaller however I'm unable to do so. The file is built and deposited in the dist folder, however when I try to run it, the the error "Failed to execute script {name}" pops up.

Here is the .spec file that I'm using:

# -*- mode: python ; coding: utf-8 -*-

block_cipher = None


a = Analysis(['simulator.pyw'],
             pathex=['C:\\Simulator'],
             binaries=[],
             datas=[('bin/**/*.kv', './bin/ui'), ('bin/**/*.xml', './bin/ui')],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=True,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=True,
          name='simulator',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          console=False , icon='bin\\ui\\icon.ico')
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=True,
               upx_exclude=[],
               name='simulator')

and this is the output from the console:

What could be the problem?

Answer 1

So you are using Kivy and it logs several errors:

picamera - ImportError: No module named picamera
  File "c:\python27\lib\site-packages\kivy\core\__init__.py", line 63, in core_select_lib
    fromlist=[modulename], level=0)
  File "c:\python27\lib\site-packages\kivy\core\camera\camera_picamera.py", line 18, in <module>
    from picamera import PiCamera

gi - ImportError: No module named gi.repository
  File "c:\python27\lib\site-packages\kivy\core\__init__.py", line 63, in core_select_lib
    fromlist=[modulename], level=0)
  File "c:\python27\lib\site-packages\kivy\core\camera\camera_gi.py", line 10, in <module>
    from gi.repository import Gst

opencv - ImportError: No module named cv2
  File "c:\python27\lib\site-packages\kivy\core\__init__.py", line 63, in core_select_lib
    fromlist=[modulename], level=0)
  File "c:\python27\lib\site-packages\kivy\core\camera\camera_opencv.py", line 48, in <module>
    import cv2

Did you declare kivy in a requirements.txt file ?

There is also

15333 INFO: Processing pre-safe import module hook   win32com
Traceback (most recent call last):
  File "<string>", line 2, in <module>
ImportError: No module named win32com
15411 INFO: Processing pre-safe import module hook   win32com
Traceback (most recent call last):
  File "<string>", line 2, in <module>
ImportError: No module named win32com

which says a library is missing (see ImportError: No module named win32com.client ).

So, how did you declare the dependencies ? We'd need to see your project structure.

Answer 2

You can check the full traceback by starting the script via command prompt.

This can be done by pressing WIN + R and writting cmd then changing the directory with cd command until you reach the folder, and then use .\\<softwarename>.exe to run.

For example:

> cd C:\softwares\test
> pwd
C:\softwares\test
> .\test.exe

From experience, this probably is caused by a ModuleNotFoundError . If that's the problem you can add the module name to the hiddenimports list at the spec.

ie: hiddenimports=['pyodbc'],

Answer 3

The problems seemed to be indeed in Kivy ( https://kivy.org/doc/stable/guide/packaging-windows.html#alternate-installations ). I modified the .spec file and the application was built successfully.
