Downloaded Sage 7.3 (the download) for the first time and learning the interface. I tried to solve a nonlinear equation of some complexity and got an error. I followed up with the following example from the Sage 7.3 tutorial manual:

g = var('g')
solve(g^2 + 3*g + 2, g)

and received this error (the same error as the equation of some complexity)

Didn't get much luck with google searches on the exact cause of this, but some sources recommended installing Xcode or iPython, though I do not have any rational to connect the reccomended solution to the original problem.


I downloaded Xcode 7.3.1 and Command Tools per the instructions,(Command_Line_Tools_OS_X_10.11_for_Xcode_7.3.1).

First I downloaded Command Tools only, and tried Sage, and the result below occurred. Next I downloaded Xcode and initialized Xcode, it did not work ... (more)

Although you shouldn't have to, please try installing the OS X Command Line Tools for Xcode as described here:

This error has appeared before and installing these tools solved it. If that works for you, then please replay back so that I can start the process to fix the error again. Thanks!

I went ahead and added an update in the original problem description, this solution did not work (I followed to the best of my ability)

I'm running El Capitan with Xcode and Command Line Tools both installed. I just downloaded the same .dmg file and the extracted .app solves the equation for me, so there should be a way to get it to work for you.

Since you've already installed Xcode, try reinstalling the Command Line Tools with the Terminal command xcode-select --install and give Sage another go. If that doesn't help, then try deleting the .app folder, extract Sage again from the .dmg file and try one more time.

Uninstalled then reinstalled command line tools and re-executed. Did not work out.

i moved the sage app from my applications folder to trash then installed sage again, did not work out.

Then i tried

rm -rf "~/.sage/"

without quotes on sage and then opened sage, tried again, and it worked out.

Thanks for the help.
