app installation problem on mac os x lion

edit

Folks, I've had a similar problem. Downloaded the Sage.app, tried launching it, then (as suggested here) tried launching from the command line. Here are the results:

209 $ /Applications/Sage-4.7.1-OSX-64bit-10.6.app/Contents/Resources/sage/sage
----------------------------------------------------------------------

    import IPython
ImportError: No module named IPython
210 $

iPython is installed in my normal Python world.

I had exactly the same problem than@Louisa Grey with the "no module named _socket"

I found the following solution :

1- install the 2.7 version of Python for OSX

2- go into the easy_install directory and type "sudo easy_install-2.7 iPython" in a Terminal bash

3- again in the same Terminal session, type "sudo easy_install readline"

then it worked fine

I had the same problem on lion (2011 MBA). I fixed it by going to python's website, downloading, and installing the latest version, as the base version of python installed on OSX is very far behind. Hope this helps!

Hi

I have installed the Sage 5.6 - OSX 10.6 on my Mac with OSX 10.7 Lion. It works pretty well until I decide to use sagetex (with TeXShop). And some problems arise: 1) I can't have the notebook anymore with safari (error message: 'can't connect to localhost:8000') while sage in the terminal works properly; 2) when I run the SageTest.sagetex.sage, I got this message:

File "/Users/janyphiphi/Library/TeXShop/Engines/Inactive/Sage/SageTest.sagetex.py", line 19, in <module> _st_.endofdoc() File "/Applications/Sage-5.6-OSX-64bit-10.6.app/Contents/Resources/sage/local/lib/python2.7/site-packages/sagetex.py", line 282, in endofdoc sagef = open(self.filename + '.sagetex.sage', 'r') IOError: [Errno 2] No such file or directory: 'SageTest.sagetex.sage' logout

Any idea?

I'm french and beginner in terminal , python, and so on, so, be pretty, be clear, as far as possible! Thanks a lot

Found the problem with the "RuntimeError: no available port." issue.

The key is:

------------------------------------------------------------
   File "<ipython console>", line 1
     b Integer(134)
             ^
SyntaxError: invalid syntax

The mac version, for whatever reason is expecting the port arg as a string, not an int.

This works:

sage: notebook(port="8000")

Note the quotes around the port number.

I am having precisely these problems also. I'm new to Sage, looking forward to learning how to use it.

Using the Sage-4.7.2-OSX-64bit-10.6.app binaries on Lion 10.7.2, with xcode 4.2, the latest iPython (32 I think), I'm able to get sage to start, with menus. The terminal shows the errors noted above. No sage prompt. When I try to open the notebook, I get the error "could not connect to localhost:8000" which I'm presuming means the server did not start.

I was considering trying to build it myself, but I've looked at the build problems in http://trac.sagemath.org/sage_trac/ti..., and I think I'll just wait to see how it goes, obviously there are a lot of little hidden nasties in the new versions of OS X and xcode to deal with.

Kind Regards, Michael Hund

just to confirm, does a non-app version of Sage, i.e. sage-4.7.2-OSX-64bit-10.6-x86_64-Darwin.dmg work for you? My understanding is that it should work. The only inconvenience is that you have to start it from Terminal...

I had the same problem. I installed Xcode and the latest python 2.7. It still didn't work until I did a manual run with

/Applications/Sage-4.7.2-OSX-64bit-10.6.app/Contents/Resources/sage/sage

Now it works fine with the app or with automatic startup. I don't know if it needed Xcode or new Python or if the manual start was enough to get it working.

Here's my Lion attempt:
