Problem within parso?

[svw26]

Hiya Matt,

Due to some 'pip problems' I thought I'd start fresh by installing RSSMOSPipeline in a new conda container. The installation (via pip install RSSMOSPipeline within the container) appears to be successful, but I run into the following SyntaxError:

I'm not familiar with parso...

Thanks, Sarah x

Hi Sarah, parso isn't part of RSSMOSPipeline - it seems to be used by IPython, which I use for debugging. So I guess IPython isn't working for you in your new conda installation?

Cheers Matt

Yeah, it appears so :( It looks like the installation downloads parso 0.8.0, when you actually need parso 0.7.0 for it to still work with Python 3.5 (https://github.com/spyder-ide/spyder/issues/13605). I've done the following to get RSSMOSPipeline output again:

1. conda uninstall parso -- this also removes ipython and jedi
2. To get those two back again, just need to conda install ipython
3. conda install parso=0.7

Thanks, Sarah x
