Argh. I just want to plot some charts in Python. Why does it have to be so hard?
I tried to
but this fails with some byzantine errors that I can’t make heads or tails with.
So after going through the tedious process of figuring out what’s wrong when a package installation fails (here, here, a here), I finally found a page that promised to take me to the land of milk and honey.
But my journey wasn’t over. OS Lion choked on
python setup.py build
So then I found this very detailed page on how to install Python, NumPy, SciPy, matplotlib and IPython on Lion.
Everything’s going well for a bit as I follow each step in order. And I get stuck on
pip install -e git https://github.com/scipy/scipy#egg=scipy-dev
with error “no matches found”. I looked around on the github repo for a tag with
but couldn’t find anything.
But I figured it out! Just build from source. This is always a last resort for me, because package managers make it so easy to install and uninstall. I’m often scared of building from source because I see a flood of matrix green letters cascading down my black background terminal. And I have no idea what’s going on. But this seems to be the only way for now until the packages are fixed.
git clone https://github.com/matplotlib/matplotlib cd matplotlib python setup.py build python setup.py install
To check your installation:
1 2 3
You should see version 1.1.0 (as of this writing) and path
To Install Scipy
git clone https://github.com/scipy/scipy cd scipy python setup.py build python setup.py install
1 2 3 4
You should see version 0.10.0 dev (as of this writing) and path
