新しい環境でAnacondaをインストールしたらSSLErrorが発生したので解決した（Windows10、Anaconda3-2019.10）

1．Anaconda3-2019.10-Windows-x86_64.exeでAnacondaをインストール

2．Anaconda Promptを開き、仮想環境を構築する際に、下記のエラーが発生

(base) C:\Users\xxx> conda create -n py36 python=3.6 anaconda
Collecting package metadata (current_repodata.json): failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/win-64/current_repodata.json>
Elapsed: -

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.

If your current network has https://anaconda.com blocked, please file
a support request with your network engineering team.

SSLError(MaxRetryError('HTTPSConnectionPool(host=\'http://repo.anaconda.com\', port=443): Max retries exceeded with url: /pkgs/main/win-64/current_repodata.json (Caused by SSLError("Can\'t connect to HTTPS URL because the SSL module is not available."))'))

3．OpenSSLはこちらからWin64OpenSSL-1_1_1d.exeをインストール（※Win64OpenSSL-1_1_0L.exeだとエラー）

4．C:\OpenSSL-Win64に展開されていたので、C:\OpenSSL-Win64\binの中身をすべてAnaconda3\Library\binにコピペ

5．Anaconda PromptからOpenSSLが使用できることを確認

(base) C:\Users\xxx>openssl
OpenSSL> exit

6．システム環境変数の確認

7．Anaconda Promptを開き、仮想環境を作成できた

(base) C:\Users\xxx>conda create -n py36 python=3.6 anaconda
Collecting package metadata (current_repodata.json): done
Solving environment: done

8．SSLのエラーは消えるが、大学内だとダメなときもあるのでテザリングで
