pipenvを使おうと思ったら pipenv shell でエラーが。

To activate this project's virtualenv, run pipenv shell.
Alternatively, run a command inside the virtualenv with pipenv run.

proc.args[0] が -/bin/bash となっているのだけど28行目でそのまま抜けてしまってそれが使われてしまっているみたい。
もとのリポジトリをたどると下のcommitで修正されていた。
pipenvのリポジトリも更新が入っていたのでそのうち直るだろう。
とりあえずは、PIPENV_SHELLという環境変数を指定するとそれが使われるようなので、
[obilixilido@srv:/work/obilixilido/w]$ export PIPENV_SHELL=/bin/bash
[obilixilido@srv:/work/obilixilido/w]$ pipenv shell

(w-ZuYzNmXn) [obilixilido@srv w]$
で解決。
しかし他に同じようにトラブってる人を見かけないのはなぜか...。
