Pipenv Install RuntimeError：場所が作成も指定もされていません

Pipenvを使用してプロジェクトの依存関係を管理しています。今までは問題なく動いていました。今私はbootstrap pipenv installと私は次のエラーを受け取ります：

HomebrewでPipenvをインストールしました。何が変更されて機能しなくなったかはわかりません。他の古いプロジェクトは引き続き機能しますが、環境を作成しようとするたびに、このエラーが発生します。

ありがとう！

だから私はそれをうまく動かすことができました。私のデフォルトpythonシステムのインストールは3.7.3。しかし、pipenvは何らかの理由でそれを気に入らなかった。インストールしましたpython 3.7.7 homebrewとpipenvを使用すると、そのバージョンを適切に特定し、それを使用して仮想環境を作成できました。

要約すると、この問題を修正するには、もう一度python=をインストールしてみてください。私の場合：

brew install python
