[toolchain v2.0] How to flash binary? (ImportError: No module named serial)

[DrSegatron]

I can flash the newly built binary with idf.py flash no problem, but how do I flash a supplied binary?

I get this tip after building from source:

Project build complete. To flash, run this command:
..\..\..\..\..\esp-idf\components\esptool_py\esptool\esptool.py -p com26 -b 921600 --after hard_reset write_flash --flash_mode dio --flash_size detect --flash_freq 40m 0x1000 build\bootloader\bootloader.bin 0x8000 build\partition_table\partition-table.bin 0x1d000 build\ota_data_initial.bin 0x20000 build\project.bin
or run 'idf.py -p com26 flash'

But when run:

Pyserial is not installed for C:\Python27\python.exe. Check the README for installation instructions.
Traceback (most recent call last):
File "C:\esp-idf\components\esptool_py\esptool\esptool.py", line 37, in <module>
import serial
ImportError: No module named serial

pyserial is already installed:

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/developme ... -2-support
Requirement already satisfied: pyserial in c:\users\jebj\.espressif\python_env\idf4.0_py2.7_env\lib\site-packages (3.4)

Edit:

Using cmd shell.

If you are using a new cmd.exe window (not the one where you were using idf.py) then run path\to\idf\export.bat first. Then you can use esptool.

Or open the "ESP-IDF Command Prompt" shortcut in start menu, it is created by the installer.

I am using the same window.

[ESP_igrr]

Ah, I see now. Can you please try adding 'python' in front of the pyserial command? I.e.

python ..\..\..\..\..\esp-idf\components\esptool_py\esptool\esptool.py -p com26 (rest of the command)

[DrSegatron]

Yes that makes it work.

But I had to restart the shell to get the message to work again:
