(Reinstall to fix it?) Error to solve simple equation

I am running sagemath 7.3 on a MacBook air 2013 with MacOS Sierra 10.12.1 (downloaded .app.dmg) but I have the following issue: When I try a simple 'solve' I get an error, literally I copy + paste the lines of an example. (I use the noteboom interface) cell

x = var('x');solve([x^2 == 4],x)

output

RuntimeError: ECL says: The function SET-LOCALE-SUBDIR is undefined.

I don't remember to have this issue in the past, (and OS upgrade get messy?) I check that Xcode is up-to-date and not sure if reinstalling it will fix it (currently doing this).


The complete output:

For this previous Ask question the solution was to reinstall Command Line Tools at the command line with

xcode-select --install

and then delete the hidden directory ~/.sage in your user's home directory before restarting SageMath.

This error was reported by me as https://trac.sagemath.org/ticket/21443.

Be careful, the directory ~/.sage contains your sage notebook worksheets.

Having encountered similar problems in the past, it was enough to remove these files:

  • ~/.sage/sage_notebook.sagenb/users.pickle
  • ~/.sage/sage_notebook.sagenb/sagenb.pid

@slelievre thanks for the clarification. The user on the previous question was brand new so this was a nonissue, but it is certainly relevant for upgrades. I've added the information to the Trac ticket and will keep it in mind when the question arises again.

The solution described here did not work for me. I am trying sage-7.5.1-OSX_10.11.6-x86_64.app.dmg on macOS Sierra (10.12.3), and I installed the latest Command Line Tools (by running xcode-select --install with Xcode 8.2.1) just before Sage. (Running again xcode-select --install returns the error message "command line tools are already installed, use "Software Update" to install updates".) Removing users.pickle did not help, and I don't have sagenb.pid. Removing the entire directory ~/.sage had no effect either. Update: I gave up on the binaries and installed Sage 7.5.1 from the source code; it seems to work.
