After updating python now I am having issues with Spyder

After updating python to solve an earlier issue I am now receiving this launch error when I try to open spyder. The error prevents me from even opening the application.

Problem Description

Traceback (most recent call last): File “/anaconda3/bin/spyder”, line 7, in from spyder.app.start import main File “/anaconda3/lib/python3.6/site-packages/spyder/app/start.py”, line 27, in from spyder.config.main import CONF File “/anaconda3/lib/python3.6/site-packages/spyder/config/main.py”, line 22, in from spyder.config.user import UserConfig File “/anaconda3/lib/python3.6/site-packages/spyder/config/user.py”, line 26, in from spyder.utils.programs import check_version File “/anaconda3/lib/python3.6/site-packages/spyder/utils/programs.py”, line 18, in import subprocess File “/anaconda3/lib/python3.6/subprocess.py”, line 136, in import _posixsubprocess ImportError: dlopen(/anaconda3/lib/python3.6/lib-dynload/_posixsubprocess.cpython-36m-darwin.so, 2): Symbol not found: __Py_set_inheritable_async_safe Referenced from: /anaconda3/lib/python3.6/lib-dynload/_posixsubprocess.cpython-36m-darwin.so Expected in: flat namespace in /anaconda3/lib/python3.6/lib-dynload/_posixsubprocess.cpython-36m-darwin.so

Just want to update that I had the same error, so it seems been have forgotten, but it was fixed via conda update python.app

Thanks for reporting. This is a duplicate of #6876 which apparently is a problem with the Mac conda executable of Python itself, and there isn’t much we can do about it. However, according to ContinuumIO/anaconda-issues#9025 you can fix it with conda update python.app.
