依存関係「std_msgs」を「std_msg」と誤って命名したことがわかりました。だから私は修正しました!、しかし待ってください、依存関係を修正したにもかかわらず、catkin はまだ lawnbot_description が依存関係として "std_msg" を望んでいると考えています:

それはまだ、lawnbot_description パッケージが「std_msg」を必要としていると考えています。なぜこれが難しいのですか？パッケージ情報を変更して更新するのは、これほど複雑ではありません。
catkin_tools clean というパッケージがあることがわかりましたが、単にワークスペースを更新するために追加のパッケージをダウンロードする必要があるのはなぜですか?
私が試してみました：
-catkin_make
-catkin_make --force-cmake
- I have seen solutions that involve deleting entire build/devel directories which horrifies me. That seems like a ton of work just to add an 's' to the end of a name
catkin clean lawnbot_description がパッケージ全体を削除するのではないかと心配しています。これは私の最良の選択肢ですか？
