Environment

  • Development Kit: none
  • IDF version (run git describe --tags to find it): v4.3.1
  • Build System: idf.py
  • Operating System: Linux - Ubuntu 18
  • Using an IDE?: No

Problem Description

Environment: Ubuntu 18, installed package python3-python (3.6.9), NO python 2 package installed, NO python-minimal

install.bat fails with error:

Creating a new Python environment in /home/georgik/.espressif/python_env/idf4.3_py3.6_env
The path python2 (from --python=python2) does not exist

Manual execution of: /usr/bin/python3 -m virtualenv /home/georgik/.espressif/python_env/idf4.3_py3.6_env' returns:

The path python2 (from --python=python2) does not exist

Root-cause: install.sh is not explicit about binary for virtualenv. Creation of virtualenv picks different Python than running instance.
Correct solution is to pass parameter -p with explicit path to the Python.
The similar solution is already in Windows Installer: https://github.com/espressif/idf-installer/blob/main/src/InnoSetup/Environment.iss#L423
Correct line should look like this:

/usr/bin/python3 -m virtualenv /home/georgik/.espressif/python_env/idf4.3_py3.6_env' -p /usr/bin/python3 --seeder pip

Note: do not forget seeder pip to avoid further problems.

Expected Behavior

Installation works.

Actual Behavior

Installation fails with message above.

Workaround: sudo update-alternatives --install /usr/bin/python2 python2 /usr/bin/python3.6 1

Steps to reproduce

  1. make sure to have Ubuntu 18, with python3 and no python (2)
  2. clone ESP-IDF
  3. execute ./install.bat

- Check if pip is installed for sys.executable before attempting to
  create the virtual environment, bail out with an error if not.
- Don't pass --seeder argument to virtualenv if its version is
  too old. For example, on Ubuntu 18.04, virtualenv 15.1.0 doesn't
  support this argument.
- Pass --python argument to virtualenv to request specific interpreter
  to be used.

Closes #8045
