我刚刚在我的 Windows 10 PC 上安装了 RailsInstaller。我无法运行rails s或rails g controller StaticPages home help.

我还尝试按照相关 StackOverflow 问题的建议通过安装 zeus gem 来解决此问题，但没有成功。

宝石文件：

source 'https://rubygems.org'

gem 'rails',        '4.2.2'
gem 'sass-rails',   '5.0.2'
gem 'uglifier',     '2.5.3'
gem 'coffee-rails', '4.1.0'
gem 'jquery-rails', '4.0.3'
gem 'turbolinks',   '2.3.0'
gem 'jbuilder',     '2.2.3'
gem 'sdoc',         '0.4.0', group: :doc
gem 'pry-nav', group: [:development, :test]

group :development, :test do
  gem 'sqlite3',     '>= 1.3.9'
  gem 'byebug',      '3.4.0'
  gem 'web-console', '2.0.0.beta3'
  gem 'spring',      '1.1.3'
end

group :test do
  gem 'minitest-reporters', '1.0.5'
  gem 'mini_backtrace',     '0.1.3'
  gem 'guard-minitest',     '2.3.1'
end

group :production do
  gem 'pg',             '0.17.1'
  gem 'rails_12factor', '0.0.2'
end

错误：

回溯告诉我们 Web 控制台 gem 需要 Ruby 的 pty 库。不幸的是，PTY（伪终端）是 Windows 上不存在的 Unix/Linux 功能，因此 Ruby 库也不存在。

您可以通过以下几种方式开始行动：

  • 如果您现在不关心 web-console gem，只需将其从 Gemfile 中删除。

  • 如果您真的需要 web-console gem，请尝试用这些 gem 替换 web-console：

    gem 'rubysl-pty', platforms: :ruby
gem 'web-console-rails3', platforms: :ruby

我通过以下步骤解决了这个问题：

  1. 首先检查你的Gemfile.lock，如果你在那里提到了bcrypt版本，那么你不需要在Gemfile中提到bcrypt版本。
  2. 如果 Gemfile.lock 中缺少 bcrypt 版本，则执行以下步骤： a) gem install bcrypt b) 打开 Gemfile 并粘贴 "gem 'bcrypt', '~> 3.1.7'" c) 在控制台中运行命令：捆绑安装

我希望按照上面给出的步骤可以解决您的问题。
