Install Prerequisites
|
|
=====================
|
|
|
|
ESP-IDF will use the version of Python installed by default on macOS.
|
|
|
|
- install pip::
|
|
|
|
sudo easy_install pip
|
|
|
|
- install CMake & Ninja build:
|
|
|
|
- If you have HomeBrew_, you can run::
|
|
|
|
brew install cmake ninja dfu-util
|
|
|
|
- If you have MacPorts_, you can run::
|
|
|
|
sudo port install cmake ninja dfu-util
|
|
|
|
- Otherwise, consult the CMake_ and Ninja_ home pages for macOS installation downloads.
|
|
|
|
- It is strongly recommended to also install ccache_ for faster builds. If you have HomeBrew_, this can be done via ``brew install ccache`` or ``sudo port install ccache`` on MacPorts_.
|
|
|
|
.. note::
|
|
If an error like this is shown during any step::
|
|
|
|
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
|
|
|
|
Then you will need to install the XCode command line tools to continue. You can install these by running ``xcode-select --install``.
|
|
|
|
Installing Python 3
|
|
-------------------
|
|
|
|
Basing on macOS `Catalina 10.15 release notes`_, use of Python 2.7 is not recommended and Python 2.7 will not be included by default in future versions of macOS. Check what Python you currently have::
|
|
|
|
python --version
|
|
|
|
If the output is like ``Python 2.7.17``, your default interpreter is Python 2.7. If so, also check if Python 3 isn't already installed on your computer::
|
|
|
|
python3 --version
|
|
|
|
If above command returns an error, it means Python 3 is not installed.
|
|
|
|
Below is an overview of steps to install Python 3.
|
|
|
|
- Installing with HomeBrew_ can be done as follows::
|
|
|
|
brew install python3
|
|
|
|
- If you have MacPorts_, you can run::
|
|
|
|
sudo port install python38
|
|
|
|
Python 2 deprecation
|
|
====================
|
|
|
|
Python 2 reached its `end of life <https://www.python.org/doc/sunset-python-2/>`_ and support for it in ESP-IDF will be removed soon. Please install Python 3.6 or higher. Instructions for macOS are listed above.
