railsでcronを実行した時、bundleとgemの読み込みでエラーが発生してしまう。

前提・実現したいこと

下記のshファイルに記載されたシェルスクリプトを実行し、記載した処理を実行したいです。

発生している問題・エラーメッセージ

cronでshファイルを実行させていますが、出力先であるログを確認すると下記のようなエラーメッセージが記載されてます。。

該当のソースコード

#!/bin/sh

cd /app/kaminari_API/kaminari_API_rails

echo "$(date): executed Lightning.download_nc_file_from_NASA" >> /var/log/cron.log 2>&1

/etc/cron.d/api_cron

*/2 * * * * root /app/kaminari_API/kaminari_API_rails/lib/tasks/dl_and_save_lightning.sh

試したこと

通常のrailsアプリ配下 /app/kaminari_API/kaminari_API_rails/のディレクトリ位置で bundleとrailsの実行ファイルのパスを確認すると、

root@27ec0cfd9457:/app/kaminari_API/kaminari_API_rails# which bundle 
/usr/local/bin/bundle
root@27ec0cfd9457:/app/kaminari_API/kaminari_API_rails# which rails
/usr/local/bundle/bin/rails

となるため、パス指定は間違ってないと思います。さらに、/app/kaminari_API/kaminari_API_railsで
rails cを打っても、

root@27ec0cfd9457:/app/kaminari_API/kaminari_API_rails# bundle exec rails c
Loading development environment (Rails 5.2.2)
[1] pry(main)>

とちゃんと起動します。なぜcronで実施した時のみ、エラーが出るのでしょうか。。

その後、色々試しています。

sh /app/kaminari_API/kaminari_API_rails/lib/tasks/dl_and_save_lightning.sh

でcronからではなく、ターミナルから直接コマンドを実行すると、ちゃんと動作してくれます。なぜcronから実行させると上記のようなエラーが出てしまうのでしょうか・・・

Sorry i was wrong. -- I dont have a good clue but it seems that you should move to the directory in which your rails project exists within your cron execution. --

thank you for commenting! in the /app/kaminari_API/kaminari_API_rails/lib/tasks/dl_and_save_lightning.sh, ``` #!/bin/sh cd /app/kaminari_API/kaminari_API_rails ``` My intention was to move to the directory in which your rails project exists. I think it works. so what is the other problem...

cronでの大きな違いとして考えられるのは環境変数の違いです。環境変数を確認してみてはいかがでしょうか。
