*Also filed this issue on git here: * https://github.com/sagemath/sage/issues/38779#issue-2568964546
*Steps To Reproduce* 1. My machine is Mac M2 with the OS Ventura 13.4 2. I already have anaconda installed: conda --version prints conda 23.10.0 3. I used the command conda create -n sage sage python=3.9 to install sage in python as explained in installation guide <https://doc.sagemath.org/html/en/installation/conda.html#sec-installation-conda> 4. Then setting the environment using conda activate sage sets the appropriate environment. 5. The following program returns an error: from sage.all import * var('a,b,c,d,x,y,z') qf = qepcad_formula ellipse = Integer(3)*x**Integer(2) + Integer(2)*x*y + y**Integer(2) - x + y - Integer(7) F = qf.exists(y, ellipse == Integer(0)); F qepcad(F) *Expected Behavior:* *There should be no error and a formula should be returned.* *Actual Behavior:* *The error reported is* Traceback (most recent call last): File "/path/anaconda3/envs/sage/lib/python3.9/site-packages/sage/interfaces/expect.py", line 521, in _start self._expect.expect(self._prompt) File "/path/anaconda3/envs/sage/lib/python3.9/site-packages/pexpect/spawnbase.py", line 354, in expect return self.expect_list(compiled_pattern_list, File "/path/anaconda3/envs/sage/lib/python3.9/site-packages/pexpect/spawnbase.py", line 383, in expect_list return exp.expect_loop(timeout) File "/path/anaconda3/envs/sage/lib/python3.9/site-packages/pexpect/expect.py", line 179, in expect_loop return self.eof(e) File "/path/anaconda3/envs/sage/lib/python3.9/site-packages/pexpect/expect.py", line 122, in eof raise exc pexpect.exceptions.EOF: End Of File (EOF).
