Wrong Python Version & Actor not found in VS Studio Code

[jasperf]

Tried to install on Mac as there is no homebrew port.. that I know of. So I used pip. But was told pygame zero uses Python 2.7.17 and o cannot install as I run Python 3.4:

pip install git+https://github.com/lordmauve/pgzero@master
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date.

ERROR: Package 'pgzero' requires a different Python: 2.7.17 not in '>=3.4'

Is there perhaps a version that does work with Python 3?

I installed pyenv to be able to switch Python versions on my Mac:

brew install pyenv
eval "$(pyenv init -)"

Then I installed requested version

pyenv install 2.7.17
Downloading openssl-1.0.2q.tar.gz...
-> https://www.openssl.org/source/old/1.0.2/openssl-1.0.2q.tar.gz

....

Then you can check version you have using:

pyenv versions

and you can switch between python versions with the command:

pyenv global version_of_choice

all based on this excellent article by Python Engineering.

However, when I ran a check and tried installing again (even reopened iTerm I still had the same Python version complaint:

pyenv versions

  2.7.17

Well, when I used pip with 2.7.17 set as Python version it did work

pip install pygame

and it also installed Idle to use with pygame from the command line. But will try to work with VS Studio Code instead.

[jasperf]

Also realized I could install pygame using Python 3 using pip3. So I added Python 3.4.0 using pyenv and installed it:

pyenv versions

  3.4.0

short test from Idle 3:

Pygame Zero has never supported Python 2. You read this error message in exactly the opposite sense:

Package 'pgzero' requires a different Python: 2.7.17 not in '>=3.4'

pgzero requires 3.4+, you were running with Python 2.7.17.

[jasperf]

I see now that I misread it all. Feeling kind of silly now.. I think I perhaps still had Python 2 running for an older Ansible setup. And after tinkering for quite some time I got back to Python 3 using pyenv. And yes, using pip3 I could then install all. Do still wonder how I managed to install a version on 2.. but perhaps it was possible but would just never work properly. Thank you work letting me know @lordmauve .

Checking Python on my MacMini now I see

jasper@MacMini  ~  brew list | grep ^python
python-tk@3.9
python@2.7.17
python@3.8
python@3.9
 jasper@MacMini  ~  which -a python python2 python2.7 python3 python3.6

/usr/local/bin/python3
/usr/bin/python3
 jasper@MacMini  ~  python --version
Python 3.9.7

and idle or idle3 both work, but Python 3 is running now so should be good to go. Just need to figure out with VS Code errors like

Exception has occurred: NameError       (note: full exception trace is shown but execution is paused at: <module>)
name 'Actor' is not defined
  File "/Users/jasper/code/galaxian/galaxian.py", line 8, in <module> (Current frame)
    bullet = Actor('bullet', center=(0, -10))

adding import pygame at the top did not help. On Raspberry Pi Galaxian worked out of the box.

Wanted to check if I had pygame installed and used pip3

As I was warned to upgrade pip I decided to do that and now pip can be used for Python 3 it seems and I can skip using pip3:

 jasper@MacMini  ~  /usr/local/opt/python@3.9/bin/python3.9 -m pip install --upgrade pip

I did a new list check and had all:

 jasper@MacMini  ~  pip list

And double checking I am using Python 3 based on Homebrew installation, not the pyenv installation:

 jasper@MacMini  ~  pip --version
pip 21.2.4 from /usr/local/lib/python3.9/site-packages/pip (python 3.9)

[jasperf]

On the actor error, I found your threads https://github.com/lordmauve/pgzero/issues/61 as well so will look into this some more to make Galaxian work on my Mac and bypass

Exception has occurred: NameError       (note: full exception trace is shown but execution is paused at: <module>)
name 'Actor' is not defined
  File "/Users/jasper/code/galaxian/galaxian.py", line 7, in <module> (Current frame)
    bullet = Actor('bullet', center=(0, -10))

[jasperf]

Hmm I read

_Update Aug 18, 2019: The screen object cannot be imported since it is created as global variable during runtime (object = instance of the Screen class) and IDE-supported code completion is not possible then. See the source code: https://github.com/lordmauve/pgzero/blob/master/pgzero/game.py (esp. the def reinitscreen part)

at https://stackoverflow.com/questions/55438239/name-actor-is-not-defined so perhaps I will have to use Idle3 instead then.. On Raspberry Pi using a PI UI I was able to run all, but perhaps there something like

PYFLAKES_BUILTINS=Actor,Rect,ZRect,animate,clock,exit,images,keyboard,keymods,keys,mouse,music,screen,sounds,storage,tone
export PYFLAKES_BUILTINS

was implemented.. will have to see. And .. one would think we can do this on MacOs as well somehow.

[jasperf]

Added

# PyGame
PGZERO_BUILTINS=Actor,Rect,ZRect,animate,clock,exit,images,keyboard,keymods,keys,mouse,music,screen,sounds,storage,tone
export PGZERO_BUILTINS

to /Users/jasper/.zshrc and restarted VS Studio Code and iTerm. Even sourced the rc file. But still seeing
