Issue

サーバーのデバッグのため，node --inspect=0.0.0.0:9229 dist/server/index.jsとしたところ，以下のようなエラーが発生しました．

[以下，最後の２行の繰り返し]

--inspect=localhost:9229でも同じです．

多分，以下と同じ問題です．

• Node process with --inspect cannot fork child process without passing --inspect nodejs/node#14325

src/server/Model/Operator/EPGUpdate/MirakurunManageModel.ts#L47が原因です．

コマンドラインオプションを引き継がないspawnやexecFileなどに置き換えることで問題を回避できると思われます．

修正する時間が取れないので、しばらくお持ちください。

PRがあれば見ます。

私もすぐに修正を行うことができません．

急いでいるわけではありませんので，このまま残しておいてもらえれば，時間ができたときに修正を試みてみます．
