some error messages like file not found can be fixed by some investigation, other's which are more complex can be googled. it's quite possible that someone else got that error and asked about it either in some github issue or some developer forum like stack overflow.
asking on irc/matrix can be helpful, you get help pretty quickly on irc/matrix specially for errors related to languages and tools. you can also get some good ideas as people there are quite experienced with software and tools.
