[FIXED] Spyder keeps crashing during load in all Anaconda environment

Issue

I was running python 2.7 in Anaconda2 in spyder 4 up until today with no problems. But now I keep getting the same error, when I make an environment and install python 2.7 and spyder in it:

Traceback (most recent call last):

This started happening after I reinstalled the package "pydicom" in the environment, and now nothing works. I have reinstalled anaconda2, used spyder --reset, and all other common suggestions.

Spyder 3.3.6 works in the base environment, but every time I make a new environment and install spyder in this, I get the same error. Any suggestions?

Solution

(Spyder maintainer here) To fix this problem, you need to install QtAwesome 0.7.3 in your environment. For that, please use the following command:

conda install qtawesome=0.7.3
