Create flask app installer using pyinstaller

Environment

Windows 10
Python3

Steps

Install
```
> pip install pyinstaller
```

Edit name.spec file

# -*- mode: python -*-
block_cipher = None
added_files = [
      ('.\\templates', 'templates'),
      ('.\\static', 'static')
      ]
a = Analysis(['__init__.py'],
          pathex=['D:\Temp\FlaskTest\flask\examples\tutorial\flaskr'],
          hiddenimports=['flask'],
          binaries=[],
          datas=added_files,
          hookspath=[],
          runtime_hooks=[],
          excludes=[],
          win_no_prefer_redirects=False,
          win_private_assemblies=False,
          cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
          cipher=block_cipher)
exe = EXE(pyz,
       a.scripts,
       a.binaries,
       a.zipfiles,
       a.datas,
       name='chartson',
       debug=False,
       strip=False,
       upx=True,
       console=True , icon='favicon.ico')

Create installer
```
> pyinstaller name.spec
```
It will create an executable file in a new dist folder under the current directory.
```
> dist\chartson.exe
```

Errors

If you execute chartson.exe , it shows an message “ModuleNotFoundError: No module named ‘flask’”. You must append the module name to hiddenimports list. Then delete these folders dist and build and run pyinstaller name.spec. Or using the command pyinstaller --clean name.spec.

Another option Pyfladesk

You can create desktop application by using Flask and QtWebEngine

Install pyfladesk and additional modules

python3 -m pip install pyfladesk
python3 -m pip install routes

Clone pyfladesk repository

git clone https://github.com/smoqadam/PyFladesk.git

Change to the example directory
```
cd PyFladesk\example
```
Start the app.
```
python3 app.py
```

Create the installer

pyinstaller -w -F --add-data "templates;templates" --add-data "static;static" app.py

Start the app. It will open the app then close it automatically. I don’t know why.
```
dist\app.exe
```
I got en error in the event log.

Use pyinstaller to create a console application

Edit console.py
```
print('hello world')
```

Edit name.spec

# -*- mode: python -*-
block_cipher = None
added_files = [
      ]
a = Analysis(['console.py'],
          pathex=['D:\pyinstaller_console_test'],
          hiddenimports=[],
          binaries=[],
          datas=added_files,
          hookspath=[],
          runtime_hooks=[],
          excludes=[],
          win_no_prefer_redirects=False,
          win_private_assemblies=False,
          cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
          cipher=block_cipher)
exe = EXE(pyz,
       a.scripts,
       a.binaries,
       a.zipfiles,
       a.datas,
       name='chartson',
       debug=False,
       strip=False,
       upx=True,
       console=True , icon='favicon.ico')

Copy a favicon.ico to the folder
Create a create_setup.bat and run it. Execute the application with the command dist\chartson.exe.
```
pyinstaller name.spec
```

Use pyinstaller to create a tkinter window application

Edit window.py

from tkinter import *
window = Tk()
window.title("Welcome to LikeGeeks app")
window.mainloop()

Create a create_setup.bat.
```
pyinstaller -w name.spec
```
The remaining steps same as Use pyinstaller to create a console application.
