https://wsvincent.com/install-python3-mac/

...I was pleasantly surprised that solved the problem without further ado - no moving files, re-installing, rolling back, etc. Everything working as expected now.

- Sat Feb 01, 2020 1:49 am #85519 I spent much time to find the solutions. Now I have solved the problems on my MacOS so that I would like to give a summary here. I hope it could help you when you meet the similar issues.

Install the CP2102 driver （USB to UART Bridge VCP Drivers）
Silicon Labs Link: https://www.silabs.com/products/develop ... cp-drivers

Check your USB cable
There could be the problem with your cable. I used the cable from my power bank. However, it was not the data cable! So please be sure that you are using a data usb cable to connect your board.

Install Python3
After I got my COM Port successfully, I still had the problem with compiling. As the picture above, it told me that it could not find Python3 file.

Library/Arduino15/packages/esp8266/tools/python3/3.7.2-post1/python3: no such file or directory

After checking online, I found the problem could be MacOS hasn't preinstalled the python3. (have a look at https://installpython3.com/mac/)

Finnally, I installed Python3 from python official website for my MacOS.

- Sat Feb 01, 2020 1:54 am #85520 But I met the error problems as following:
► No COM Port: I chose the board NodeMCU 1.0 (ESP-12E module), but I cannot find my COM PORT in TOOLS
► Error Compiling: I upload the blink for a test, but it showed ERROR as
Library/Arduino15/packages/esp8266/tools/python3/3.7.2-post1/python3: no such file or directory

- Wed May 06, 2020 2:27 am #86941 Most likely, the problem is that you're using a relative file path to open the file, but the current working directory isn't set to what you think it is.

It's a common misconception that relative paths are relative to the location of the python script, but this is untrue. Relative file paths are always relative to the current working directory, and the current working directory doesn't have to be the location of your python script.

You have three options:

Use an absolute path to open the file.

Generate the path to the file relative to your python script.

Change the current working directory before opening the file
