pipenvでdotenvをinstallできなかった問題【解決済み】

おや？　dotenvをpipenvでインストールしようとしたらエラーが出た。

[pipenv.exceptions.ResolutionFailure]: Warning: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies.
You can use pipenv install --skip-lock to bypass this mechanism, then run $ pipenv graph to inspect the situation.
Hint: try pipenv lock --pre if it is a pre-release dependency.
ERROR: No matching distribution found for dotenv

Pipfileを見てみる。

修正前

Pipfile

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
dotenv = "*"

修正後

Pipfile

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
python-dotenv = "*"

dotenvがpython-dotenvになってなかったね。これでOK。
