我在加载设计 gem 时出错：

Something went wrong while loading config.ru

Bundler::GemNotFound: Could not find gem 'devise (~> 3.5.1) ruby' in any of the gem sources listed in your Gemfile or available on this

这是我的 gems 文件中的内容：

source "https://rubygems.org"

gem "sinatra"
gem "activerecord"
gem "sinatra-activerecord"
gem "rake"
gem 'devise', '~> 3.5.1'
gem "rack-ssl-enforcer"
gem "haml"


group :development do
  gem "pry"
  gem "shotgun"
  gem "tux"
  gem "sqlite3"
end

我不知道它可能是什么。我做了捆绑安装，它安装了设计gem。当我删除设计时，一切正常。

【问题讨论】：

标签： ruby-on-rails ruby ruby-on-rails-3 devise gem

【解决方案1】：

您是否尝试过仅使用 gem 'devise'？如：

gem 'devise'

版本 3.5.1 是最新的（在撰写本文时），因此默认情况下它应该安装最新版本（除非你这样做的原因我错过了）。

【讨论】：

我收到此错误：执行 gem 时 ... (Gem::CommandLineError) 未知命令设计。当我尝试捆绑更新时，我得到这个错误：Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension。 /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby extconf.rb 检查 C 编译器是否接受 ... 是检查 C 编译器是否接受 -Wno-error=unused-command-line- argument-hard-error-in-future... no Building nokogiri using packaged libraries...
如何从我的计算机上完全卸载所有 gem？

【解决方案2】：

config.ru 出错 Bundler 找不到 gem 设计 3.5.1 所以，尝试运行bundle update

【解决方案3】：

固定：

问题在于安装设计的依赖项之一：nokogiri。

我关注this guide 安装 nokogiri 并排除故障，现在已解决。
