rails 新博客安装失败

rails new blog failing to install

我正在按照教程在 Rails 博客上设置一个简单的 Ruby,但是当我输入 "rails new blog" 时,出现以下错误。 有谁知道问题出在哪里?我没有使用 Rails 的经验,最近才开始学习 Ruby,希望能提供帮助。谢谢!

Ruby版本:ruby2.5.3p105(2018-10-18修订版65156)[x64-mingw32] Rails版本:Rails5.2.3 OS: Windows 10 64 位

我已经尝试了命令提示符中的建议,运行 行:

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

但是我得到这个错误:

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

你会试试这个吗gem? 它可能必须弄清楚。

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

Gemfile

gem 'sqlite3'替换为

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