Hello, I wanted to download an open source and run a python file for 2D mapping. But it keeps giving me an error that the module doesn't exist. I did a search on the site, but couldn't find an answer that worked for me. How do I install this module?

It’s telling you that ‘)’ is missing. From the function generate_launch_description the return statement is not properly closed.

I'm sorry to have to do this for something so seemingly unimportant, but please don't post screenshots of terminal text in questions on ROS Answers. It's all text, so there is no need. Just copy-paste the text from the terminal into your question text. Do make sure to format it properly by selecting the text and pressing ctrl+k (or clicking the Preformatted Text button (the one with 101010 on it)).

You don't need to post a new question, just edit your curent one. You can use the edit button/link for this.

After you replace the screenshot with the error message itself, we can re-open your question.
