ImportError: No module named html

I'm stuck trying to run the example code:
https://github.com/jwkvam/bowtie-demo/blob/master/example.py

I believe I have all dependencies installed via conda and pip (plotlywrapper), and I've tried running it in several environments and consoles.

Thanks for the report! Can you check what version of bowtie you have installed?

python -c "import bowtie; print(bowtie.__version__)"

If you're not running 0.9.1, please upgrade and try again. If you are running 0.9.1 please let me know.

My mistake I went into the python shell and executed the code line by line and no errors at:

from bowtie.html import Markdown

./example.py in my system terminal results in:

(py36bowtie) users-MacBook-Pro:bowtie-demo-master user$ ./example.py
Usage: example.py [--help] COMMAND [ARGS]...

Bowtie CLI to help build and run your app.

Options:
--help Show this message and exit.

Commands:
build Write the app, downloads the packages, and...
dev Recompile the app for development.
prod Recompile the app for production.
run Build the app and serve it.
serve Serve the Bowtie app.
(py36bowtie) users-MacBook-Pro:bowtie-demo-master user$

Looks like my IDE was having path issues with v0.9.1 and v0.8.1 has the issue

Cool, thanks for confirming :)
