"source activate env" not running after update "unsupported format character"

[Gareth]

Hi

I updated conda and now I have an error not easily found on the web or stackoverflow.

I'm on macOS 10.13.2

I updated conda/hombrew/npm all around the same time and only now vaguely remember noticing that conda(?) was updating futures.

I mention this because it was referenced in an unrelated but similar bug report.

Thanks in advance

Gareth
