Anvi-interactive won't run with cherrpy>=9.0

[jmeppley]

My latest installs have been failing because pip is now up to cherrypy 10.0. The issue comes up when I launch anvi-interactive:

Traceback (most recent call last): File "/Users/jmeppley/anaconda3/envs/anvio/lib/python2.7/multiprocessing/process.py", line 258, in _bootstrap self.run() File "/Users/jmeppley/anaconda3/envs/anvio/lib/python2.7/multiprocessing/process.py", line 114, in run self._target(*self._args, **self._kwargs) File "/Users/jmeppley/anaconda3/envs/anvio/lib/python2.7/site-packages/bottle.py", line 3117, in run server.run(app) File "/Users/jmeppley/anaconda3/envs/anvio/lib/python2.7/site-packages/bottle.py", line 2777, in run from cherrypy import wsgiserver ImportError: cannot import name wsgiserver

It seems that, as of cherrypy 9.0, the wsgiserver module in cherrpy has been relocated. Technically, this is probably a bug with the dependency definitions in bottle, but it might be worthwhile for anvio users to limit cherrypy to versions <9.

I see this problem both with the pip installed anvio (2.1.0) and the python3 version of anvio (the new-profiling branch). I don't have a working install from the master branch to test with, sorry.

Hi John,

I realized that a very short while ago and fixed the requirements.txt in the master (https://github.com/merenlab/anvio/commit/d23bb1f584e6fc49787a074baa4bebd3e99244f7) :/

We clearly need to stick with explicit version numbers in the requirements just to make sure things will not fail in the long run. My mistake.

I know you don't need any help to resolve it, but I updated the installation manual, and I've been referencing people who complain about this error to this e-mail:

When py3 repo is merged to master the fix will be in affect. Sorry for the inconvenience, and thank you for the report.
