pip install でSSL証明書関連？のエラー

pip installしようとすると、下記のエラー。

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/pip/

Requirement already up-to-date: pip in ./.anyenv/envs/pyenv/versions/3.7.3/lib/python3.7/site-packages (19.0.3)

SSL関連のエラーっぽいので、とりあえずOpenSSLを入れ直したりしてみる。

brew install openssl

が、ダメ。~/.pip/conf.pipにtrustedの設定を追加してもダメ。

解決

Pythonとpipを再インストールすると解決した。pyenvを使っていたので、

pyenv install 3.8.0

pyenv global 3.8.0

curl -kL https://bootstrap.pypa.io/get-pip.py | python

を実行後、再度pip installを実行すると問題なく動いた。

もやもやするけど、動いたから一旦よしとしておこう。。。
