Just did a clean install (i.e. on formatted drive) of the OS and IDE, updated the preferences with... http://arduino.esp8266.com/stable/packa ... index.json
...included the 8266 boards, etc. Everything seemed to go OK, but compiling Blink I get...
Arduino: 1.8.10 (Mac OS X), Board: "Adafruit Feather HUZZAH ESP8266, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:2MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 115200"
fork/exec /Users/twc/Library/Arduino15/packages/esp8266/tools/python3/3.7.2-post1/python3: no such file or directory
Error compiling for board Adafruit Feather HUZZAH ESP8266.
...the problem is the targeted file is an alias that doesn't resolve. Digging a little deeper, I notice elsewhere in the ESP8266 file hierarchy there's a 'staging' folder with python3-macosx-placeholder.tar.gz. This might be related to issues you can see by googling 'esp8266 python file does not exist', but a solution didn't leap out. It seems like I have to gather/move a python executable? Any help appreciated, thanks in advance.
