I'm getting this exact issue on Python 3.5 (xenial system installation).
All my existing venvs (from before my upgrade to xenial) work. Here's the diff:
> diff .venv/bin/activate.fish ../wrapt/.venv/bin/activate.fish
35c35
< set -gx VIRTUAL_ENV "/home/tin/pg/hypothesis/.venv"
---
> set -gx VIRTUAL_ENV "/home/tin/pg/wrapt/.venv"
58,59c58,59
< if test -n "$(.venv) "
< printf "%s%s%s" "$(.venv) " (set_color normal) (_old_fish_prompt)
---
> if test -n "(.venv) "
> printf "%s%s%s" "(.venv) " (set_color normal) (_old_fish_prompt)
The added dollar signs are the issue. Removing them fixes the problem.
For the record:
> fish --version
fish, version 2.2.0
And here's the actual error message, the same as in the png:
> . .venv/bin/activate.fish
$(...) is not supported. In fish, please use '(.venv)'.
.venv/bin/activate.fish (line 58): if test -n "$(.venv) "
