Ruby on Rails中的Bcrypt gem

Question

I've just created a fresh Rails 5 application. I don't have any MVC's generated yet inside my application.

I added some gems to the gem file including gem 'bcrypt', '3.1.11' .

When I try to create a controller with the rails generator, I get an error.

This is the command with the error that I got:

command > rails generate controller StaticPages home help

All I did was add gems to my gemfile, so I'm not sure why the rails generator isn't working.

I did notice that my generator stops working when I add the gem bcrypt .

Can someone tell me the reason I can't use my generator once I installed gem 'bcrypt', '3.1.11' ?

Answer 1

从gem文件中删除gem'bcrypt'，'3.1.11'并使用$ gem install bcrypt
