If it helps, even devs have problems following the install instructions.
It could be for a lot of reasons. Usually it's because it's open source and we can't test it for every possible configuration. Or we are just trying to code, not deal with the dozen other setups.
Me in particular, all my application projects don't include node versions, and assume Linux. Even I forget that sometimes if I'm loading a old project and suddenly it doesn't build, and I have to futz around for an hour eupdating packages.
If it makes you feel even better, I'm a software engineer and I had lots of trouble learning to use GitHub and git, it's embarrassing to admit it but I'm super glad I learned!
Git isn't properly taught. I've studied programming both in college and in a boot camp, and both times they rushed right over git, showing only the bare essentials. This left me unprepared for the real world. I didn't know how to do basic stuff like exclude files or even undo changes.
It's so complex, they really should have a separate class for it.
Same. I learned about the 'releases' section only recently thanks to some kind Lemmy user (kinder than some I've seen on Lemmy and reddit discussing this same image, some people are openly supporting gatekeeping of software).
