Getting an error when starting a rails app server

Question

Part of the traceback on terminal says

There was an error while trying to load the gem 'jbuilder'. (Bundler::GemRequireError)

Please help

Gemfile:

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.5.1'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '~> 5.2.2'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use Puma as the app server
gem 'puma', '~> 3.11'
...
gem 'jbuilder', '~> 2.5'
...

Answer 1

也许您可以尝试“捆绑安装”？

Answer 2

我不确定，但尝试检查config / database.yml，然后尝试：捆绑安装-如果不配置开发，则不进行开发测试：和测试：或仅对它们进行注释。

Answer 3

the issue was the various ruby versions I had installed on my machine. The solution was, I removed them and reinstalled ruby using rvm.
