Rails Generate Controller给我加载错误

Question

I try to generate a controller but it gives me this error. I can't find where in my files what caused this error so help would be much appreciated. I am running Ruby '2.0.0' and rails '4.2.0.beta2' if that helps at all. PLEASE help! Thanks

I don't undestand WHY this post is getting marked as a duplicate. My question has nothing to do with that other question. Plus, I am asking what to do to fix it, and as far as I read, I didn't even see a fix to that error. PLEASE HELP!

Answer 1

The problems is the Rails 4.2.0.beta depends on the pty gem and is unable to find it:

`require': cannot load such file -- pty

The reason is that the pty gem is not available on Windows. Hopefully that gets fixed before Rails 4.2 is released. At the moment you can fix this problem by removing the web-console gem from your Gemfile :

# Gemfile
# gem 'web-console'

Run bundle install after removing that gem.

To fix the problem that no source of timezone data could be found (TZinfo::DataSourceNotFound) please add the following line to your Gemfile :

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]

And then try again:

bundle install
bundle exec rails generate controller StaticPages home help
