Currently ESP_PYTHON is used in the install.sh script, but it's
overwritten in detect_python.sh. This allows to explicitly specify
python binary, which should be used to create venv.
$ ESP_PYTHON=/usr/bin/python3.7 ./install.{sh,fish}
$ ESP_PYTHON=/usr/bin/python3.7 ./export.{sh,fish}

# This is a helper script for detecting Python executables in the PATH. It is intended to be used for determining
|
|
# which Python should be used with idf_tools.py for installing tools and exporting environment variables.
|
|
#
|
|
# 1. The script is looking for python version same or greater than minimal required version on path
|
|
# 2. If required version of python is found it is assigned to environmental variable `ESP_PYTHON`
|
|
# 3. If required version of python is not found, script will fail
