As a rule of thumb, don't ever install anything into /opt/local/ other than via the port command. The reason for installing packages with -user is that if instead you install packages using sudo python setup.py install, the packages will be installed inside the MacPorts tree, but MacPorts won't be aware of it, so this could cause issues in future if the package is installed via MacPorts. Note that you can also install packages in a similar way using easy_install-2.7 and pip-2.7 by specifying the -user option. This will place user installed packages in ~/Library/Python/2.7/lib/python/site-packages where they will automatically be picked up by the Python installation, without messing up the MacPorts file structure. pydistutils file if you have one, then simply use: When installing packages not in MacPorts, first make sure that you remove your. Sudo port install py27-aplpy +montage -rgb For example, the following will install APLpy with support for Montage, but not for RGB images: To include a variant not installed by default, use +variant. To remove a default variant, use -variant. Variants listed with are installed by default. Universal: Build for multiple architectures Montage: Include support for Montage reprojection To check if a package is available through MacPorts, you can do:īe sure to install the one for the correct Python version ( py27-* if you've been using the above instructions).īefore installing the package, you can check what variants are available:Īvm: Include support for AVM meta-dataĭs9: Include support for DS9 region files Note that this is optional - you can also invoke this Python installation by using python2.7 and ipython-2.7. Make this Python installation the default: These settings are likely to be the most useful for plotting astronomical data. Optionally, you can uncomment and set the image.origin and image.interpolation lines to This ensures that when you use Matplotlib interactively, a window will pop up. matplotlib/matplotlibrc and change the following line matplotlib in your home directory and copy the default matplotlibrc file to it:Ĭp /opt/local/Library/Frameworks/amework/Versions/2.7/lib/python2.7/site-packages/matplotlib/mpl-data/matplotlibrc ~/.matplotlib/Įdit.

If you want to install these, use sudo port install py27-atpy +sql) and sudo port install py27-aplpy +montage respectively). MacPorts will automatically take care of any dependencies! (by default SQL dependencies are not installed for py27-atpy, and the Montage dependency is not installed for py27-aplpy. Sudo port install py27-pyfits py27-pywcs py27-atpy py27-aplpy To install Astronomy packages, use for example: Note that this will probably take several hours, and is best done overnight. Sudo port install py27-matplotlib py27-numpy py27-scipy py27-ipython To install most of the basic Python packages, run: Go to the terminal and update the package index:.
