Thanks a lot!
I have tried to compile python from source. However, the problem remains.
Is it because I still didn’t compile python successfully to work with gdb? Here is the make test result
----------------------------------------------------------------------
Ran 73 tests in 1.854s
FAILED (failures=5)
test test_urllib2 failed
3 tests failed again:
test_gdb test_urllib2 test_venv
Total duration: 13 min 22 sec
Tests result: FAILURE
make: *** [test] Error 1
Focus on one: /Users/Natsume/Downloads/Python-3.6.2/debug
I tried to compile it twice, but the same result like above.
What else should I try? thanks!
