Installation issue with pip v10

[Derek Matthew Croote]

With a fresh conda env I have an issue installing changeo with the latest version of pip on my Linux machine. Interestingly, this is solved by downgrading pip:

$ conda create -n ct python=3 cython numpy scipy pandas
$ conda activate ct

$ python --version
Python 3.6.5 :: Anaconda, Inc.

$ pip --version
pip 10.0.1

$ pip install changeo --no-cache-dir

$ pip install pip==9

$ pip install changeo --no-cache-dir

Not sure if you can reproduce?

Greetings @dcroote,

Yeah, v0.3 won't install with pip 10. We fixed this is ceb3ba6, but we've been slow in getting v0.4 out the door.

You could install the latest build from the bitbucket and it should work, but it has a lot of changes since v0.3.

If you need v0.3, you should be able to install it by just replacing the setup.py file with the current one from bitbucket. You'd have to remove lines 35-36 (BuildTrees and ConvertDb install) as they are new to v0.4.

We'll try to get v0.4 out next week though. fingers crossed.

Ah I wasn't thinking- yes right you are, everything works!

Apologies, Derek
