using pyinstaller with setuptools

[VISHESH MANGLA]

I do not have knowledge of the jargons here. I created a python package with setup.py the first time and now I want to create a windows installer.

https://github.com/pyinstaller/pyinstaller/issues

```setup.py

import setuptools

setuptools.setup(

    name="mailerkivy",

    version="0.1.1",

    url="..",

    author="..",

    author_email="..",    

    python_requires='>=3.7',

    packages=setuptools.find_packages("src"),

    package_dir={"": "src"},

    entry_points={

        "gui_scripts": [

            "mailer = mailer.main:main",

        ],

    },

        setup_requires="setuptools",

    install_requires=[

        "kivy>=2.0.0",

        "beautifulsoup4>=4.9.3",

        "docxtpl>=0.11.3",

        "pywin32>=300",

        "plyer>=2.0.0"

        

    ],

   extras_require={

        "build_for_windows":  ["pyinstaller>=4.2", "pyinstaller"],

    }

)

```

```b.spec

def Entrypoint(dist, group, name, **kwargs):
    import pkg_resources

    # get toplevel packages of distribution from metadata
    def get_toplevel(dist):
        distribution = pkg_resources.get_distribution(dist)
        if distribution.has_metadata('top_level.txt'):
            return list(distribution.get_metadata('top_level.txt').split())
        else:
            return []

    kwargs.setdefault('hiddenimports', [])
    packages = []
    for distribution in kwargs['hiddenimports']:
        packages += get_toplevel(distribution)

    kwargs.setdefault('pathex', [])
    # get the entry point
    ep = pkg_resources.get_entry_info(dist, group, name)
    # insert path of the egg at the verify front of the search path
    kwargs['pathex'] = [ep.dist.location] + kwargs['pathex']
    # script name must not be a valid module name to avoid name clashes on import
    script_path = os.path.join(workpath, name + '-script.py')
    print("creating script for entry point", dist, group, name)
    with open(script_path, 'w') as fh:
        print("import", ep.module_name, file=fh)
        print("%s.%s()" % (ep.module_name, '.'.join(ep.attrs)), file=fh)
        for package in packages:
            print("import", package, file=fh)

    return Analysis(
        [script_path] + kwargs.get('scripts', []),
        **kwargs
    )

Entrypoint('mailerkivy', 'gui_scripts', 'mailer.main')

```

After building the exe , this error pops up  if I run it from the cmd.   Looks the same , most of it.

https://stackoverflow.com/questions/48884766/pyinstaller-on-a-setuptools-package  None of the answers seem to work given here.

```b.spec

# -*- mode: python -*-

block_cipher = None

def Entrypoint(dist, group, name,
               scripts=None, pathex=None, hiddenimports=None,
               hookspath=None, excludes=None, runtime_hooks=None):

    import pkg_resources

    # get toplevel packages of distribution from metadata
    def get_toplevel(dist):
        distribution = pkg_resources.get_distribution(dist)
        if distribution.has_metadata('top_level.txt'):
            return list(distribution.get_metadata('top_level.txt').split())
        else:
            return []

    hiddenimports = hiddenimports or []
    packages = []
    for distribution in hiddenimports:
        packages += get_toplevel(distribution)

    scripts = scripts or []
    pathex = pathex or []

    # get the entry point
    ep = pkg_resources.get_entry_info(dist, group, name)
    # insert path of the egg at the verify front of the search path

    pathex = [ep.dist.location] + pathex

    # script name must not be a valid module name to avoid name clashes on import
    script_path = os.path.join(workpath, name + '-script.py')

    print ("creating script for entry point", dist, group, name)

    with open(script_path, 'w') as fh:
        print("import", ep.module_name, file=fh)
        print("%s.%s()" % (ep.module_name, '.'.join(ep.attrs)), file=fh)
        for package in packages:

            print ("import", package, file=fh)

    return Analysis([script_path] + scripts, pathex, hiddenimports, hookspath, excludes, runtime_hooks)

a = Entrypoint('mailerkivy',
    'gui_scripts',
    'mailer',
    
    
)

pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          name='Mailer',
          debug=False,
          strip=False,
          upx=True,
          runtime_tmpdir=None,
          console=False ,
           icon='./src/mailer.ico' )
```

I even tried putting  pathex= pathex=[r'C:\Users\Dell\OneDrive\Desktop\MailerKivy\src\mailer', r'C:\Users\Dell\OneDrive\Desktop\MailerKivy',
    r'C:\Users\Dell\OneDrive\Desktop\MailerKivy\src\mailerkivy.egg-info'
    ],

It didn't work then too.
