pkg_resources.DistributionNotFound: The 'PyInstaller'...

[Salim9304]

OS: Linux
pyinstaller: v4.0
environment: pipenv
python: v3.7

I would like to put together a simple code using the 'Folium' library
simple code

program.py

from PyInstaller.utils.hooks import collect_data_files
datas += collect_data_files('branca', subdir='templates')
datas += collect_data_files('folium', subdir='templates')
    
import folium
print("Hello!")

pyinstaller -F --clean program.py
OK

when I try to run the executable I get the error:
_Traceback (most recent call last):
File "program.py", line 1, in
File "", line 983, in _find_and_load

pkg_resources.DistributionNotFound: The 'PyInstaller' distribution was not found and is required by the application
[15296] Failed to execute script 1

I tried to solve the problem as stated here:
#5256
#5262

I opened the file:
site-packages/branca/element.py
Replaced the line:
ENV = Environment(loader=PackageLoader('branca', 'templates'))
to

import sys
if getattr(sys, 'frozen', False) and hasattr(sys, '_MEIPASS'):
    import os
    from jinja2 import FileSystemLoader
    bundle_dir = getattr(sys, '_MEIPASS')
    data_dir = os.path.abspath(os.path.join(bundle_dir, 'branca', 'templates'))
    ENV = Environment(loader=FileSystemLoader(data_dir))
else:
    ENV = Environment(loader=PackageLoader('branca', 'templates'))

and
site-packages/folium/raster_layers.py
ENV = Environment(loader=PackageLoader('folium', 'templates'))
to

import sys
if getattr(sys, 'frozen', False) and hasattr(sys, '_MEIPASS'):
    import os
    from jinja2 import FileSystemLoader
    bundle_dir = getattr(sys, '_MEIPASS')
    data_dir = os.path.abspath(os.path.join(bundle_dir, 'folium', 'templates'))
    ENV = Environment(loader=FileSystemLoader(data_dir))
else:
    ENV = Environment(loader=PackageLoader('folium', 'templates'))

No effect the same error. Is there any way to solve the problem?

You're getting the error because you are trying to import PyInstaller in your program.

This block

from PyInstaller.utils.hooks import collect_data_files
datas += collect_data_files('branca', subdir='templates')
datas += collect_data_files('folium', subdir='templates')

should be placed into your .spec file, not the program (.py) file.

Are you sure this Linux solution works?

my code
program.py

import folium
print("Hello!")

my spec

mode: python ; coding: utf-8

from PyInstaller.utils.hooks import collect_data_files
datas = collect_data_files('branca', subdir='templates')
datas += collect_data_files('folium', subdir='templates')

block_cipher = None


a = Analysis(['program.py'],
             pathex=['/home/salim/test/folium'],
             binaries=[],
             datas=datas,
             hiddenimports=['geopandas.datasets','branca','folium'],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],
          name='program',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          upx_exclude=[],
          runtime_tmpdir=None,
          console=True )

pyinstaller -F --clean program.spec
OK

after running the executable:
FileNotFoundError: [Errno 2] No such file or directory: '/tmp/_MEIFug4aJ/branca/_cnames.json'

@Phoenix009
Can you share your solution?

FileNotFoundError: [Errno 2] No such file or directory: '/tmp/_MEIFug4aJ/branca/_cnames.json'

You need to collect all branca data files, not just its template subfolder:

from PyInstaller.utils.hooks import collect_data_files
datas = collect_data_files('branca')
datas += collect_data_files('folium', subdir='templates')

Good.
