Error while running the exe file made with pyinstaller

问题

I tried to make a standalone executable of my python script with auto-py-to-exe , it basically provides easy interface for creating executable with pyinstaller, so I made my python script's exe, it's console based and when I try to run the exe that I made of my script, then console opens up for a second a closes with bunch of errors quickly. However, the script runs fine in idle. I had attached a screenshot of the error I received. As per my observations most probably the error is occurring due to the import of VLC module as in error trace you will see it occurred from line 2 and that line I had imported VLC. I have also observed by changing the line number of import for VLC. I am quite a beginner, So I need to know the steps for the solution.

from bs4 import BeautifulSoup
import vlc
import pafy
import urllib.request
import time


textToSearch = 'tremor dimitri vegas ' 
query = urllib.parse.quote(textToSearch)
urlq = "https://www.youtube.com/results?search_query=" + query
response = urllib.request.urlopen(urlq)
html = response.read()
soup = BeautifulSoup(html, 'html.parser')
track_links=[]
i=0
for vid in soup.findAll(attrs={'class':'yt-uix-tile-link'}):
    i=i+1
    print('https://www.youtube.com' + vid['href'])
    track_links.append('https://www.youtube.com' + vid['href'])
    if i==2:
        break
print()


url = track_links[1]
video = pafy.new(url)
best = video.getbestaudio()
playurl = best.url
ins = vlc.Instance()
player = ins.media_player_new()

code = urllib.request.urlopen(url).getcode()
if str(code).startswith('2') or str(code).startswith('3'):
    print('Stream is working and playing song')
else:
    print('Stream is dead')

Media = ins.media_new(playurl)
Media.get_mrl()
player.set_media(Media)
player.play()

time.sleep(20)
player.stop()#breaking here just for check purpose

now here is the complete error trace

Python VLC needs external dependencies like the DLL you see in the error. So you need to add them to your executable output with add-data.

Just copy all *.dll inside your current VLC install path (e.g C:\Program Files\VideoLAN\VLC) besides to your script and use below command to generate your executable:

pyinstaller.exe -F --add-data "./libvlc.dll;." --add-data "./axvlc.dll;." --add-data "./libvlccore.dll;." --add-data "./npvlc.dll;." script.py

Edit: It seems that you still need one more dependecy which is plugins directory. Just add the whole plugins directory in your VLC path to your executable output. For that after executing above command you would get a spec file add a.datas += Tree('<path_to_vlc_plugins_dir>', prefix='plugins') to the file like this:

# -*- mode: python -*-

block_cipher = None


a = Analysis(['script.py'],
             pathex=['<root_project_path>'],
             binaries=[],
             datas=[('./libvlc.dll', '.'), ('./axvlc.dll', '.'), ('./libvlccore.dll', '.'), ('./npvlc.dll', '.')],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)

a.datas += Tree('<path_to_vlc_plugins_dir>', prefix='plugins')
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],
          name='script',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          runtime_tmpdir=None,
          console=True )

Finally, execute this:

pyinstaller script.spec
