condaでyamlから環境を再構築しようとしてエラーが出た時の対処法
起こった問題
conda env export > hoge.yml
を使って仮想環境に含まれているパッケージのリストをyamlファイルに書き出し、
conda env create -n envname -f hoge.yml
を実行して hoge.yml
に書かれた仮想環境を再構築しようとしたところ、以下のエラーが出現して実行できませんでした。

解決方法
このページ の "AFTownsend commented on 15 May 2019" のコメントを参考に
VSCodeでhoge.yml
のエンコーディングを見てみると、UTF-16 LE になってました。
そこで、エンコーディングの所をクリックしてUTF-8に変更して保存しなおしたら、
問題なく
conda env create -n envname -f hoge.yml
を使って仮想環境を再構築できるようになりました。
