Version conflict in editable install

[theoreticalbts]

Do the following steps:

• Do a fresh git clone into a local directory
• Install into a freshly created virtualenv with pip -e
• Run txgen.py

Then get this error:

Traceback (most recent call last):
  File "/home/theoretical/ve/tn/lib/python3.6/site-packages/pkg_resources/__init__.py", line 635, in _build_master
    ws.require(__requires__)

During handling of the above exception, another exception occurred:

pkg_resources.DistributionNotFound: The 'toml==0.9.3.1' distribution was not found and is required by steem

I am going to add requirements.txt, and then add -r requirements.txt to the command line, see if that fixes the issue.

Nope, that didn't work. It says:

Collecting toml==0.9.3.1 (from -r /home/theoretical/src/tinman/requirements.txt (line 25))

later on it says:

It works fine with non-editable install. This just means you have to do pip install --upgrade path/to/tinman whenever you edit the files in the tinman directory, which is a pain for iterative development :(
