do it manually： can see that the 'esptool' module exists

I tried adding 'peintf('\n aaa \n')' to 'D:\software\esp.espressif\python_env\idf5.0_py3.8_env\Scripts\esptool.py' and 'D:\software\esp.espressif\python_env\idf5.0_py3.8_env\Lib\site-packages\esptool.py', but I don't see the output, but I can see two outputs when I add it to 'd:\software\esp\esp-idf\components\esptool_py\esptool\esptool.py', apparently 'd:\software\esp\esp-idf\components\esptool_py\esptool\esptool.py' is importing itself

If 'idf.py' is used, it is normal

I renamed 'esptool.py' to 'esptool2.py' and executed it manually, the result is correct： Although there is a 'No such file or directory: 'main.bin'' error in the middle, it is simply solved

Hello @xiaguangbo, thank you for the detailed report, this will help us a lot! ~~There are reports of this issue in the esptool repository: https://github.com/espressif/esptool/issues/740~~ EDIT: not the same thing We will fix this ASAP.

dotlambda commented 2 years ago

@radimkarnis I assume it's the same thing. The reason this happens is that sys.executable is in d:\software\esp\.espressif\python_env\idf5.0_py3.8_env\Scripts while esptool.py is in d:\software\esp\esp-idf\components\esptool_py\esptool. It's definitely a case fixed by https://github.com/espressif/esptool/pull/742.

radimkarnis commented 2 years ago

@dotlambda This issue seems to be a result of this wrapper script importing itself. This wrapper is a part of ESP-IDF and serves as a compatibility layer. You can see that in this one, we try to remove the path to the script itself:

    sys.path.remove(os.path.dirname(os.path.realpath(__file__)))  # do not import this script

https://github.com/espressif/esptool/pull/742 concerns a wrapper script, which is directly in the esptool repository. The issue is similar, but I don't think both of these can be solved in the same place.

RavioliSauce commented 2 years ago

@dotlambda I was getting the same "module 'esptool' has no attribute '_main'" error. Your fix worked for me! I am now able to communicate with my ESP8266!

radimkarnis commented 2 years ago

@RavioliSauce, thanks for confirming this! Could you please verify if this also solves the issue?

xiaguangbo commented 2 years ago

@radimkarnis Today I reinstalled the whole environment and it works fine, I don't know if this is a code fix or something is wrong with my previous environment

radimkarnis commented 2 years ago

@xiaguangbo thanks for the info and cooperation!

We have released esptool v4.0.1 with a fix. Hopefully, this definitely solves the issue.

wreyford commented 2 years ago

I used ESP-IDF setup in Visual Studio Code insiders, and installed Master and tools using the interface, on a Windows10 PC, and got the same issue now. I cannot flash my code to ESP32-S3-DevKitC-1

xiaguangbo commented 2 years ago

@wreyford Delete the esptool_py folder and use git pull, delete ./espressif/python_env and reinstall using the install script, try

hola cuando intento flashear un esp32 me sale este error Traceback (most recent call last): File "C:\Users\Osniel\AppData\Local\Programs\Python\Python312\Scripts\esptool.py", line 37, in esptool._main() ^^^^^^^^^^^^^ AttributeError: module 'esptool' has no attribute '_main'

como pudiera solucionar esto

LAestafa commented 1 month ago
