OSX ships with an older version of Python. Install using Homebrew:
brew install python
This installs Python alongside the version in OSX. To access this version, it's necessary to run:
➜ python --version Python 2.7.16 # <- Still the old OSX version! ➜ python3 --version Python 3.7.4 # <- This is the version we want
pip3 (instead of
➜ pip --version pip 19.1.1 from /usr/local/lib/python2.7/site-packages/pip (python 2.7) ➜ pip3 --version pip 19.1.1 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)
Finally, it's necessary to add the path to Python 3.7 /bin, in
# If you come from bash you might have to change your $PATH. export PATH=/Users/<MYUSERNAME>/Library/Python/3.7/bin:$PATH
If you want to replace “python3” and “pip3” with “python” and “pip”, add this:
# /usr/local/opt/python/libexec/bin <- makes python3 the default when calling python export PATH="/usr/local/opt/python/libexec/bin:$PATH"
After that, running “python” will use the newer version by default.
