- Thu Oct 29, 2020 3:54 am #89244 I've got the same issue. I did try EVERYTHING! and can't get it work. I did downgrade all the way down to version 2.7.2 (of ESP), I did downgrade ArduinoIDE down to 1.8.12, I did erase all ESP packages and performed manual install (over terminal over git), I did download esptools package directly to Python (over pip command). I did even forget all Arduino IDE and tried make everything manually with the help of makeEspArduino (downloaded files into Documents folder and worked all out of there). NOTHING did work. Always the same outcome: "pyserial or esptool directories not found next to this upload.py tool."

I am so desperate now. I should mention I am running macOS 11.0 Big Sur.

edit:
I have managed to get it work through the makeEspArduino. It is important to install the esptool (via pip3 command) with sudo, since espmake has to be run with sudo as well. I think I've had to override folders makeEspArduino and esp8266 with 0755 privilege, not sure tho'.

However ArduinoIDE has still got the same issue. Cannot figure that out. And since I don't need it as I use VSCode anyways, I just don't use it.

I got the same problem of my MacOS Big Sur since the update and I did the following :

1. Download https://github.com/espressif/esptool/archive/v3.0.zip
2. Download https://github.com/pyserial/pyserial/archive/v3.4.zip
3. Extract the contents to esptool/ and pyserial/ in the ~/Library/Arduino15/packages/esp8266/hardware/esp8266/2.7.4/tools/ folder (an equivalent must exist on Windows)

Everything works now

Hello, thanks for your post! I did it like you describes it. I found two older folders (pyserial and esptool). Both I renamed to old-... than I take the old names to both new folders. Do I have to delete the old folders with the names old-..., because it still does not work on my Mac with Big Sur. It is the same report when I try to send the sketch to my ESP8266.
