Question

我找到了project on GitHub，但我在运行它时遇到了问题。有人可以尝试让我知道如何做到这一点吗？

我下载了项目，在rails上启动了一个新项目，转到myapp /并尝试rails s但是它没有启动。

我安装了所有宝石，现在它向我显示了这个错误：C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/sqlite3-1.3.13-x64-mingw32/lib/sqlite3.rb:6:in require': cannot load such file -- sqlite3/sqlite3_native (LoadError)

像这样看我的gemfile

source 'https://rubygems.org'

git_source(:github) do |repo_name|   repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")   "https://github.com/#{repo_name}.git" end

基本上要让任何回购工作在本地，您需要检查的第一件事是Gemfile和Database.yml

以下是步骤

将zip和Extract下载到您想要的位置。
打开项目并转到database.yml并使用正确的数据库适配器，用户名和密码（适用于所有环境）在测试环境中使用sqlite3。您可以将其更改为postgresql以解决错误。
在gem文件中包含您用作数据库的gem。如果您使用mysql2作为适配器，那么在Gemfile中添加该gem。
捆绑安装。（这将产生新的依赖关系，如果你在这里得到版本控制错误然后删除Gemfile.lock并再次捆绑安装[试试这个作为最后的尝试，尽管不推荐]）
rake db：create and rake db：migrate
然后按s

如何启动现有项目轨道？
