MacOS Installation¶
Binary Installers¶
OSX install has become a challenge. With the Enthought transition to Canopy we cannot figure out clean install directions for 3rd party packages and therefore can no longer recommend using EPD for SpacePy.
Python¶
The Python that ships with OSX is not going to work. We recommend Python 2.7 from http://www.python.org/download/
Numpy¶
There is an OSX package at http://sourceforge.net/projects/numpy/files/NumPy/1.7.1/
Scipy¶
There is an OSX package at http://sourceforge.net/projects/scipy/files/scipy/0.12.0/
Matplotlib¶
There is an OSX package at http://matplotlib.org/downloads.html
CDF¶
If you wish to use CDF files, download and install the NASA CDF library. The default installation directory is recommended to help SpacePy find the library. There is an OSX install package.
- Get the package from ftp://cdaweb.gsfc.nasa.gov/pub/software/cdf/dist/cdf34_1/macosX/
- Unzip and install
ffnet¶
easy_install –user ffnet
SpacePy¶
With the dependencies installed, SpacePy is ready to build and install. This uses the same basic setup as ffnet (standard Python distutils).
Build:
python setup.py build
If this fails, specify a FORTRAN compiler:
python setup.py build --fcompiler=gnu
(python setup.py build --help-fcompiler
will list options for
FORTRAN compilers.)
Install for one user:
python setup.py install --user
Or install for all users on the system:
sudo python setup.py install
Full MacPorts Install Instructions¶
These were current as of 13-May-2013, path especially go out of date quickly. We recommend installing this way for the best results.
Dependencies¶
- Install xcode from the app store
- Open xcode
- Xcode -> preferences -> Downloads -> install command line tools
- Install MacPorts (http://www.macports.org/install.php)
- sudo port -v selfupdate
- sudo xcode-select -switch /Applications/Xcode.app
- sudo port install gcc49 +gfortran
- sudo port select gcc mp-gcc49
- sudo port install python27
- sudo port select –set python python27
- sudo port install py27-ipython py27-scipy py27-numpy py27-matplotlib readline py27-h5py ipython-select
- sudo port select –set ipython ipython27
- Download spacepy source (or clone from git) (http://spacepy.lanl.gov/download.shtml)
INSTALL SPACEPY¶
- python setup.py install -–user (in the spacepy directory after unzip)
POST INSTALL TWEAKING¶
- Create .matplotlib/matplotlibrc
- Add: backend : MacOSX
- Add: interactive : True
