error trying to start tileserver - ImportError: cannot import name on_invalid_geometry_make_valid

[songololo]

I am getting this error when attempting to start tilserver:

I get this when using git tags 0.5.0, 0.5.1, 0.6.1 and on Ubuntu 14.04 and 16.04

Traceback (most recent call last):
  File "/tileserver/tileserver/__init__.py", line 5, in <module>
    from tilequeue.command import make_queue
  File "/usr/local/lib/python2.7/dist-packages/tilequeue/command.py", line 9, in <module>
    from tilequeue.format import lookup_format_by_extension
  File "/usr/local/lib/python2.7/dist-packages/tilequeue/format/__init__.py", line 3, in <module>
    from tilequeue.format.mvt import encode as mvt_encode
  File "/usr/local/lib/python2.7/dist-packages/tilequeue/format/mvt.py", line 1, in <module>
    from mapbox_vector_tile.encoder import on_invalid_geometry_make_valid
ImportError: cannot import name on_invalid_geometry_make_valid

Is this a circular dependency of some sort?

Thanks.

Looks like it's expecting a new version of mapbox-vector-tile. Can you try using mapbox-vector-tile 0.3.0?

[songololo]

I'm explicitly installing map box vector tile via pip, which uses version 0.3.0, and still seem to be getting the error.

Here are my build steps:

sudo apt-get update \
    && apt-get install -y git build-essential autoconf libtool pig-config \
    python-dev python-virtualenv libgeos-dev libpq-dev python-pip python-pil \
    libmapnik3.0 libmapnik-dev mapnik-utils python-mapnik

# avoids an errors when running requirements.txt
pip install pip --upgrade
pip install python-dateutil
pip install mapbox-vector-tile

git clone https://github.com/tilezen/tileserver.git
cd /tileserver
git checkout tags/v0.6.1
pip install -U -r requirements.txt
python setup.py develop

[songololo]

It seems that setup.py installs mapbox-vector-tile v0.0.11.

If I upgrade mapbox-vector-tile after running setup.py then it upgrades the following:

However, the error still occurs.

Sorry, I was too hasty in my response. Seems like that function doesn't actually exist in that tag. Can you try mapbox-vector-tile master?

If that works for you and you'd prefer to point to a tag, I can push out what's currently on master to a new 0.4.0 release.

[songololo]

Thanks, what ended up working in the end was cloning and running setup.py on the master branch for each of these (in this order)

1. tilserver,
2. mapbox-vector-tile,
3. tilequeue

[rmarianski]

Great! Glad to hear it works for you and sorry for the confusion. Let us know if you want us to release a new tag.
