anacondaでconda createを実行しようとすると「 Solving environment: failed 」と出て実行できなかった

Last updated at Posted at 2019-01-23

環境

Windows10 64bit
anaconda3(2018.12)

解決法

anacondaディレクトリ内の\Library\binをpathに追加するだけ

至るまでの経緯

anacondaをインストールして機械学習用の環境を構築しようと思い、他記事を参考にcreateコマンドを打ってみた所以下のエラーが発生


>conda create -n deep python=3.5 anaconda
Solving environment: failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/pro/win-64/repodata.json.bz2>
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://www.anaconda.com blocked, please file
a support request with your network engineering team.

SSLError(MaxRetryError('HTTPSConnectionPool(host=\'repo.anaconda.com\', port=443): Max retries exceeded with url: /pkgs/pro/win-64/repodata.json.bz2 (Caused by SSLError("Can\'t connect to HTTPS URL because the SSL module is not available."))'))

エラー文でググってみると、sslを無効にすれば出来ただとかcondaをアップデートしろだとか出てきたが行っても解決せず
(condaに至ってはupdateコマンド打っても同様のエラー発生で実行できない)

困り果てながら探していると以下のコメントを発見

言われるがままにpathへ追加した後コマンドを打ち込むと成功


>conda create -n deep python=3.5 anaconda
Solving environment: done
