由于 Nokogiri，加载设计时出错 Gem

Question

我在加载设备时遇到错误 gem:

Boot Error

Something went wrong while loading config.ru

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

我不知道它会是什么。我做了 bundle install，它安装了这个装置 gem。当我删除设计时，一切正常。

Answer 1

您试过只使用 gem 'devise' 吗？如：

gem 'devise'

Ver 3.5.1 是最新的（截至撰写本文时），因此默认情况下它应该安装最新版本（除非我错过了您这样做的原因）。

Answer 2

config.ru 出错 Bundler 找不到 gem devise 3.5.1 所以，试试运行 bundle update

Answer 3

固定：

问题在于安装设计的依赖项之一：nokogiri。

我按照 this guide 安装 nokogiri 和解决问题，现在已经解决了。

由于 Nokogiri，加载设计时出错 Gem
