"python" has been detected

Adding ESP-IDF tools to PATH...

Using Python interpreter in /home/jk007/.espressif/python_env/idf4.4_py3.6_env/bin/python

Checking if Python packages are up to date...

Python requirements from /home/jk007/esp/esp-idf/requirements.txt are satisfied.

Added the following directories to PATH:

  /home/jk007/esp/esp-idf/components/esptool_py/esptool

  /home/jk007/esp/esp-idf/components/espcoredump

  /home/jk007/esp/esp-idf/components/partition_table

  /home/jk007/esp/esp-idf/components/app_update

Done! You can now compile ESP-IDF projects.

Go to the project directory and run:



  idf.py build
