Question

我正在遵循一个教程来建立一个简单的Ruby on Rails博客，但是当我输入“ rails new blog”时，出现以下错误。有人知道问题出在哪里吗？我没有使用Rails的经验，最近才开始学习Ruby，我们将不胜感激。谢谢！

Ruby版本：ruby 2.5.3p105（2018-10-18修订版65156）[x64-mingw32] Rails版本：Rails 5.2.3 操作系统：Windows 10 64 bit

我在命令提示符下尝试了建议，并运行以下行：

gem install sqlite3 -v '1.4.0' -- source 'https://rubygems.org/'

但我收到此错误：

最初运行后出现错误：rails新博客

An error occurred while installing sqlite3 (1.4.0), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.4.0' --source 'https://rubygems.org/'`
succeeds before bundling.

In Gemfile:
  sqlite3

这是gem_make.out文件中的内容

Answer 1

您会尝试这个宝石吗？它可能必须弄清楚。

gem 'sqlite3', git: "https://github.com/larskanis/sqlite3-ruby", branch: "add-gemspec"

Answer 2

宝石文件

将gem 'sqlite3'替换为

gem 'sqlite3', git: "https://github.com/larskanis/sqlite3-ruby", branch: "add-gemspec"
