When I try to install Pylivetrader in Anaconda on Mac, the install fails with following message. I created separate environment with Python 3.5, 3.6 and 3.7, the pylivetrader install fails on all listed versions of Python. I tried installing both through Anaconda Navigator and through Terminal command line. Both failed. Also, alpacahq channel shows pylivetrader version 0.0.29 in Anaconda.
UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
- pylivetrader -> python[version='2.7.*|3.4.*|>=2.7,<2.8.0a0|>=3.7,<3.8.0a0|>=3.8,<3.9.0a0|3.3.*|3.6.*']
Your python: python=3.5
If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.
The error message with Python 3.6 is slightly different.

Output in format: Requested package -> Available versions
I’m experiencing these issues as well, any workarounds?
I was able to install it on an environment using python 3.5 but any version greater than that causes issues with a package within Pylivetrader called bcolz which has stopped being maintained.
