[python-control-discuss] Installation problem

[Alan Z. <a.z...@sh...>]

To install control-Python Ryan Krauss advised me to type:

     sudo python setup.py install

in Terminal on my Mac.

I obtain:

Python2012 alanzinober$ sudo python setup.py install
Password:
running install
running bdist_egg
running egg_info
writing control.egg-info/PKG-INFO
writing top-level names to control.egg-info/top_level.txt
writing dependency_links to control.egg-info/dependency_links.txt
error: package directory 'src' does not exist
unknown-78-ca-39-b1-18-cf:Python2012 alanzinober$

src does not exist ?     Perhaps from a different Python installation 
package.

I am using Python2.7 on a Mac.
I installed Pythons using      fonnesbeck-ScipySuperpack-fb2fc07 .

I believe that I have installed scipy, numpy and matplotlib, and other 
items in the package.

Perhaps more detailed instruction for control-Python might assist me.

Strange.  Here's what I got running this on a Mac running 10.7.3:

Which version of the package did you download?

In your debugging effort, first make sure that you are invoking the correct Python binary by looking at

$ which -a python

To see the details of the installation process, call Python with the "-v" flag (for "verbose").  I suggest redirecting to a plain text file so that you can grep for keywords.  E.g.,

$ sudo python -v setup.py install > foo.txt 2>&1
$ grep -i numpy foo.txt
