Ubuntu 22.04でpipenvのPkgResourcesDeprecationWarningエラーが出るとき

したいこと

@Ubuntu22.04, Python3.10 がデフォルトなのですが、3.9を使いたい

前提として、 pyenv とpipenvをインストールしてあります

エラー

pipenvをインストールしようとするとこのエラー

/usr/lib/python3/dist-packages/pkg_resources/__init__.py:116: PkgResourcesDeprecationWarning: 0.1.43ubuntu1 is an invalid version and will not be supported in a future release

対処その1

このissueを見ると、バグらしく、 環境変数を書くといいらしい。

$ SETUPTOOLS_USE_DISTUTILS=stdlib pipenv install

この書き方で進んだのですが、

initできていない気がする。Macでやったときは 初期のPipfileが作成された気がしたのですが。

対処その2

しかたないので、当該フォルダにPipfileを作って入れておきます。例

[[source]]

url = "https://pypi.org/simple"

verify_ssl = true

name = "pypi"

[packages]

requests = "*"

numpy = "*"

pytest = "6.2.4"

[dev-packages]

[requires]

python_version = "3.9"

エラーは出るけど成功しました。3.9が入っていないのでpyenvで同時に作っています。
