`block in load_missing_constant'：启动 Rails 服务器和控制台时未初始化的常量 Pry::Command::ExitAll (NameError)

Question

我正在 rails 上开始一个新项目，由于“撬”gem 的错误而无法启动 rails 服务器或控制台（我想..现在开始怀疑）

我的宝石文件看起来像这样：

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

ruby '2.6.5'


gem 'rails', '~> 6.0.2', '>= 6.0.2.2'
gem 'pg', '>= 0.18', '< 2.0'
gem 'puma', '~> 4.1'
gem 'sass-rails', '>= 6'
gem 'webpacker', '~> 4.0'
gem 'turbolinks', '~> 5'
gem 'jbuilder', '~> 2.7'

gem 'bootsnap', '>= 1.4.2', require: false

gem 'autoprefixer-rails'
gem 'font-awesome-sass'
gem 'simple_form'

group :development, :test do
  gem 'pry-byebug'
  gem 'pry-rails'
  gem 'dotenv-rails'

end

group :development do
  gem 'web-console', '>= 3.3.0'
  gem 'listen', '>= 3.0.5', '< 3.2'
  gem 'spring'
  gem 'spring-watcher-listen', '~> 2.0.0'
end

group :test do
  gem 'capybara', '>= 2.15'
  gem 'selenium-webdriver'
  gem 'webdrivers'
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

撬宝石版本：

pry (0.13.0)
pry-byebug (3.9.0)
pry-rails (0.3.9)

每当我尝试启动控制台或服务器时，这就是我得到的：

我尝试卸载 pry 并重新安装它但没有成功。 有任何想法吗？

Answer 1

@mcout 现在我自己有了这个，我通过将我的 gemfile 中的psy-byebug版本升级到至少 3.9.0 来修复它

给它一个bundle install后它工作......

也许这有助于这些天出现同样错误的人......
