I'm relatively new to Ruby and Rails, been teaching myself in free time. I recently added a few gems to my gemfile, and now my scaffold is giving me errors--couldn't find another answer on StackOverflow that addressed my issue (apologies in advance if my search prowess isn't up to par).

As you can see it seems to be having an issue when it gets to the "_form.html" part of the scaffold generation.

I checked to make sure there were no strange permissions on files. I suspect it has something to do with Foreman (which is a Heroku thing), or maybe dotenv (which is necessary for local development stuff, so I can store secrets). I found some posts elsewhere about previous beta versions of rails 5.1 have issues with Thor, but I don't even know what Thor does (it is some dependency) and they said that that bug was fixed on subsequent releases (e.g. I'm using 5.2 anyway).

My other theory is that it's related to Jbuilder and json stuff, which I'm also new to, and don't even know where to begin to tackle.

Any ideas? In the meantime I'm going to work without scaffolding.

Anyway, thank you for your time!

Thank you for your time!

Update!

Well, I solved the problem on my own, and just wanted to report back. So, I forgot I had had trouble installing Nokogiri as well. Whenever I ran "bundle update" I was getting an error that said I needed to make sure the latest version of Nokogiri was installed correctly before continuing. I ignored this, because I couldn't figure out out. This was solved by simply following the instructions at nokogiri.org and installing the necessary libraries:

sudo apt-get install build-essential patch ruby-dev zlib1g-dev
liblzma-dev

gem install nokogiri

After I did this I thought to myself "Uh, duh, this is probably the solution to the scaffolding issue." Indeed it was.
