How to fix error with pyinstaller after compilation in exe

Question

I compiled a Python script into an exe file, but after opening the exe, the console opens and an error occurs, then the console immediately closes. Perhaps this is due to the fact that I am using downloaded libraries (web3, bs4, hdwallet, bip_utils)

Traceback (most recent call last):

It seems like you need to copy the files that your project uses in to the exe. To do this you need to add-data when running pyinstaller. You can use pyinstaller spec files to configure the settings of your compilation.

Here is a example of spec file (you need to modify it for your use):

a = Analysis(['C:\\path\\to\\your\\main\\py file.py'],
             pathex=['C:\\path\\to\\search\\for\\imports'],  
             binaries=[],
             datas=[('C:\\Users\\username\\AppData\\Local\\Programs\\Python\\Python38\\Lib\\site-packages\\package\\xxxx\\yyyyy\\*', '.\\package\\xxxx\\yyyyy'),
             ('C:\\Users\\username\\AppData\\Local\\Programs\\Python\\Python38\\Lib\\site-packages\\package2\\zzz\\*', '.\\package2\\zzz'),
             ],
             hiddenimports=["a_package"], #A list of module names (relative or absolute) that should be part of the bundled app
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=None,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=None)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],
          name='nameOfExe',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          upx_exclude=[],
          runtime_tmpdir=None,
          console=False,
          icon='icon.ico') # specify icon

You can check other parameters and what they do from Pyinstaller docs.

This file can be run using:

python -m PyInstaller -F main.spec --clean
