任意のアイデアをどのような問題はここにある可能性がありますか？事前に多くの感謝。

Answer 1

こちらを参照してください。 https://github.com/conda/conda/issues/3929

問題は、暗号パッケージの古いバージョンでした。これは、実行することによって固定することができますだけでなく、Windows上で動作するSSL証明書の検証を無効にする

CONDA_SSL_VERIFY=false conda update pyopenssl 

Answer 2

別の方法：

は.condarcファイルにssl_verify: Falseを追加します。

.condarcファイルはデフォルトでは含まれていませんが、最初にconda configコマンドを実行したときにユーザーのホームディレクトリに自動的に作成されます。

次のコマンドを使用することができssl_verifyを設定するには：

conda config --set ssl_verify Falseを。
