pip 21.2.3 from /usr/local/lib/python3.9/site-packages/pip (python 3.9) Python 3.9 also comes with pip, the package installer for Python. To use Python 3.9, invoke python3.9 or its absolute paths /usr/local/bin/python3.9 instead. $ python3 -Vīoth give the same output like this. However, you still use it the same way as before, by invoking python3, python3.8, or their absolute paths /usr/bin/python3 and /usr/bin/python3.8. Python 3.8 is the default Python version. Using make altinstall instead of make install avoids overwriting Python 3.8 with Python 3.9. Installing Python 3.9 side by side with Python 3.8 is better than overwriting Python 3.8 because it allows existing programs that are not compatible with the new version to continue to work.
When finished, you have a Python 3.9 binary suitable for a production installation. The -s option tells make to print only warnings and errors. The -enable-optimizations flag actives all stable optimizations.īuild the source (this may take a few minutes). $ tar xzf v3.9.7.tar.gzĬhange the working directory to the source directory.
