Standard Setup of Toolchain for macOS¶
ESP-IDF will use the version of Python installed by default on macOS.
sudo easy_install pip
install CMake & Ninja build:
It is strongly recommended to also install ccache for faster builds. If you have HomeBrew, this can be done via
brew install ccacheor
sudo port install ccacheon MacPorts.
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
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:
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:
If above command returns an error, it means Python 3 is not installed.
Below is an overview of steps to install Python 3.
Python 2 deprecation¶
Python 2 reached its end of life and support for it in ESP-IDF will be removed soon. Please install Python 3.6 or higher. Instructions for macOS are listed above.
To carry on with development environment setup, proceed to Step 2. Get ESP-IDF.
