Pyinstaller找不到libvlc.dll

Question

首先，我知道有人问过类似的问题，但我无法找到解决我的问题的方法。谢谢您的帮助！

我一直在尝试使用 pyinstaller 创建可执行文件，但无法让 pyinstaller 找到 libvlc 的 .dll。特别是：libvlc.dll 和 libvlccore.dll。这些位于我的 VideoLAN\VLC 目录中，但我还将所有 dll 从我的 VideoLAN\VLC 目录复制到我的 Compile 目录中，位于我的 test.py 和 test.spec 文件旁边。我还将 VideoLAN\VLC 目录添加到我的环境变量中，试图帮助 pyinstaller 找到它们。 尽管如此，当我运行 pyinstaller test.spec 时，我收到此警告：

48352 WARNING: lib not found: libvlccore.dll dependency of C:\Users\chipc\Desktop\Code\Python\KivyTest\KivyTut\Compile\libvlc.dll

其余的编译日志可以在这里看到：https://pastebin.com/DJmkQ7nm

当尝试运行生成的 test.exe 时，它给了我这个：

Traceback (most recent call last):
File "site-packages\PyInstaller\loader\pyiboot01_bootstrap.py", line 149, in __init__
File "ctypes\__init__.py", line 356, in __init__
OSError: [WinError 193] %1 is not a valid Win32 application

During handling of the above exception, another exception occurred:

[16044] Failed to execute script test

此外，生成的包含test.exe的文件夹中确实有libvlc.dll。

这是我的 test.spec 文件：

# -*- mode: python ; coding: utf-8 -*-
from kivy_deps import sdl2, glew
block_cipher = None


a = Analysis(['test.py'],
             pathex=[('C:\\Users\\chipc\\Desktop\\Code\\Python\\KivyTest\\KivyTut\\Compile'), ('C:\Program Files\VideoLAN\VLC')],
             binaries=[('./libvlc.dll', '.'), ('./axvlc.dll', '.'), ('./libvlccore.dll', '.'), ('./npvlc.dll', '.')],
             datas=[],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
a.datas += Tree('C:\\Program Files\\VideoLAN\\VLC\\plugins', prefix='plugins')
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=True,
          name='test',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          console=True )
coll = COLLECT(exe, Tree('C:\\Users\\chipc\\AppData\\Local\\Programs\\Python\\Python37-32\\Lib\\site-packages\\kivy_deps'),
               a.binaries,
               a.zipfiles,
               a.datas,
               *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
               strip=False,
               upx=True,
               name='test')

该程序在 PyCharm 中运行。如何让 pyinstaller 找到 libvlc.dll？

以防万一，这是我的编译目录的样子：

axvlc.dll
libvlc.dll
libvlccore.dll
npvlc.dll
test.py
test.spec

感谢您的帮助，我这几天一直在努力解决这个问题！

我有同样的问题，我删除了vlc应用程序和vlc模块，问题是因为vlc应用程序适用于32位而我的电脑是64位，然后安装了64位vlc应用程序，然后再次下载了vlc模块并添加了libvlc的路径。 dll 到系统变量，一切顺利......

这是我的 Google 搜索中不断出现的没有答案的堆栈帖子之一。

您是否尝试过将

libVLC.dll

添加到二进制文件行中，如下所示：

a.binaries + [("libVLC.dll", "D:\KivySchool\VLC\libvlc.dll", "BINARY")],

我看到这行

exclude_binaries=True,

，也许删除它？我的工作规范文件中没有该行。

示例测试.py

from sys import platform

if platform == "win32": #https://docs.python.org/3/library/sys.html#sys.platform
    import vlc
    import os
    import time

    vlc_player = vlc.MediaPlayer() 
    medianame = "bigbuckbunny x265.mp4"
    mediapath = os.path.join(os.path.dirname(__file__), medianame)
    media = vlc.Media(mediapath)
    vlc_player.set_media(media)
    vlc_player.play()
    offset = 5
    time.sleep(offset)
    length = vlc_player.get_length() #time in ms (divide by 1000 to get in seconds)
    newoffset = length/1000 - offset
    time.sleep(newoffset)

示例规格文件

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

medianame = "bigbuckbunny x265.mp4"

a = Analysis(
    ['basicpyvlc.py'],
    pathex=["D:\KivySchool\VLC"],
    binaries=[("D:\KivySchool\VLC\plugins\*", "plugins")],
    datas=[(medianame, ".")],
    hiddenimports=[],
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    noarchive=False,
)
pyz = PYZ(a.pure)

exe = EXE(
    pyz,
    a.scripts,
    a.binaries + [("libVLC.dll", "D:\KivySchool\VLC\libvlc.dll", "BINARY")],
    a.datas,
    [],
    name='basicvlc',
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    upx_exclude=[],
    runtime_tmpdir=None,
    console=True,
    disable_windowed_traceback=False,
    argv_emulation=False,
    target_arch=None,
    codesign_identity=None,
    entitlements_file=None,
)

适用于：Win 10、x64 VLC、PyInstaller 6.3.0
