VS code install OK.  Python on mac using the terminal command as written in the guide on page 25 resulted in errors as posted below.  I have installed ver 3.11 from  https://www.python.org/downloads/macos/  
but it contains a few warnings about the M1 silicon and also some certificates it needs.

Update.  I just noticed on:    https://code.visualstudio.com/docs/?dv=osx.     that there is a number of TOP EXTENSIONS
of which Python is one. Is there a reason NOT to use it instead of your recommendation????
Jim

Hi.
I think maybe the command was broken during copy-paste.
Can you try to copy it from here:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Then, run the following:

brew install python3

Let me know if this works.
Regards,
Sara

Your first command certainly produced a lot of text within terminal and initially appeared to work.
the second command “brew install python3” did not progress.  On closer inspection, there seems to be a problem with a PATH allocation.  It seems that I have to follow some instructions to fix things.  I will try to get to this at some stage but I currently have a grand-daughter for 2 days and she is very demanding of my attention.
Below is the last portion of the text in the terminal.   
In a more positive note, I managed to download the blink sketch to my ESP32 DEVKIT V1 – DOIT but it wont blink the onboard LED.  Maybe LED 2 is not the correct one for this case? I have a second DEVKIt I can try to see if it fails as well.  (When I find time).    Regards, Jim
Thank you for your assistance.

Hi.
Yes, the installation of brew was successful.
But, you need to fix the command path. You need to run the following commands in this order:

echo "export PATH=/opt/homebrew/bin:$PATH" >> ~/.zshrc

brew doctor

brew install python3

Let me know if this fixes the issue.

Sara

HEY SARA ..  I did a spotlight search on Macintosh HD and found that Brew is actually there!
Path is Macintosh HD>OPT>homebrew>bin>brew.   as shown in the status bar of “Finder”
 

Hi.
It seems there is some issue with your brew installation.
Let’s try to fix it using the following commands.

1) Unninstall:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

2) Then, install again:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

3) Now, add bre to the Path variable:

echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bash_profile

echo 'export PATH="/usr/local/bin:$PATH"' >> $HOME/.zshrc

4) Try to install python again:

brew install python3

Let me know if this works.

Regards,
Sara

Hi.
There seems to be an issue with the MAC OS version (https://github.com/orgs/Homebrew/discussions/446)
Can you try the following two commands:
 

eval "$(/opt/homebrew/bin/brew shellenv)"

brew install python3

 
Tell me what you get.
Regards,
Sara

Appears to be successful and below is a paste of the last section from the terminal window.
However, I have a new problem regarding my Blink code download to my ESP32. It appears to upload ok but it doesn’t RUN the code.  I Shutdown V studio code and opened Arduino IDE, selected the board (DEVKIT V1 -DOIT 36 pins) and uploaded and successfully saw the blue LED blink. (also blinked an Ext. LED on GPIO 2) I S/D IDE, re-launched V studio code & Downloaded.  The blinking stopped and the Terminal window seemed to indicate a success.  So I know it’s not the ESP32 module itself.  (Same USB port designation checked!). Just doesn’t seem to run. (Tried boot PB and EN PB to no affect). Noted that the Arduino IDE upload didn’t require me to press the boot PB)

you’ll need to read your database using the older version of Homebrew Python and convert to another format.
`dbm` still defaults to `dbm.gnu` when it is installed.

Hi.
Do you get any errors on the Serial Monitor?
How does your platformio.ini file look like?
Are you sure you uploaded the code? There are the option to compile and the option to upload. Are you sure you clicked on the upload button?
 
Regards,
Sara

Terminal output suggested all ok.  Definitely did an upload which explains why previous Arduino blinking led went out.  Simply didn’t run on ESP.  Spent another hour installing software on Win 11 V.M. WAS looking good until I was getting requests to access folders on my Mac OS.  Wasn’t thinking straight but now realise that I should have isolated the VM from the MacOS.
The good news is that I have a working install on my Windows 10 Dell Laptop and now a successful upload and blinking LED.  I believe I haven’t done the MacOS install in correct order and so Platform IO extension done before the python install.  Maybe I’ll start again from scratch  I am thinking that perhaps I should stick with Windows but preferably Windows 11 on an isolated VM.  (I also remembered that I have a Ubuntu VM on the Mac Studio. ) So now I have too many choices. At least with Windows OS I can open device manager and see comm port designations.
11 pm here time to sleep.  Send me your thoughts on the above.  Thanks for your help. Jim.

Hi.
To be honest, I don’t know why you’re getting the issue with the blinking project on MAC OS, but I don’t think it’s related to the order you installed the software.
 
You can try to start from scratch just to make sure and try it out once again…
 
Let me know your results.
 
Regards,
Sara

Hi Sara. Have abandoned the MacOS and managed to get things going OK on the Windows11 “Parallels” Virtual Machine.  I isolated the VM from the Mac to begin with.  This caused 2 problems.  The network connection was preventing VCS to get extensions.  It had to do with DNS settings etc. Somehow I got it working. Then I couldn’t upload the blink Led and after looking at DEVICE MANAGER determined it needed The CP2102 USB to UART Bridge driver installed. I removed the isolation from the Mac but haven’t uninstalled VCStudio as yet.  So I have 2 working installations – The windows 10 Dell Laptop and the Windows11 VM.  This will aid in fault-finding in the future plus provide portability to projects.  For any future calls for help, shall I start a different help session?
Regards, Jim

Hi.
Yes. I’ll mark this issue as resolved now.
If you need further help, you just need to open a new question in our forum.
Regards,
Sara
