ESP32,ESP-WROOMをArduino IDEで使う(No module named serialエラー)

UbuntuのpythonはPython2.7なのでPython3を使う

~/.arduino15/packages/esp32/hardware/esp32/1.0.5/platform.txt

の

tools.esptool_py.network_cmd=python "...

tools.gen_esp32part.cmd=python "...

recipe.objcopy.bin.pattern.linux=python "...

tools.esptool_py.upload.pattern.linux=python "...

これらの行を以下のように編集。

...=python "...

↓なのを

...=python3 "...

へ、変更
