WSL2でpipenv installができないときのメモ

概要

• WSL2でPythonを使っている
• WindowsではPythonを使っていない
• pipenvがうまく動かない

詳細

WSL2でpipenv installをつかうと以下の様なエラーがでた。

~/d/jupyter ❯❯❯ pipenv install

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

Windows側にPythonを入れていないのにPythonのパスがある。
これはWindowsStore用のPythonリンクに繋がっている。

どうもWSL内からコマンドを叩いてもWindows側のコマンドが優先される様子。

対応方法

python.exeを削除する。
しかしエクスプローラーからだとエラーが出て削除できないので、管理者権限のプロンプトから削除を行う。

管理者権限cmd

cd C:\Users\xxxx\AppData\Local\Microsoft\WindowsApps
del python.exe
del python3.exe
