我在Stack Overflow上找不到我的问题的答案，我认为这可能是因为在遵循youtube教程后，我以错误的方式安装了SQLite3。
我按照本教程安装SQLite https://www.youtube.com/watch?v=zOJWL3oXDO8&t=176s。我最初在SQLite网站上的Windows的“预编译二进制文件”部分下安装了http://sqlite-tools-win32-x86-3260000.zip。我提取了文件，然后将其粘贴到C：\ sqlite（我将文件夹的名称更改为sqlite）。然后，我去编辑系统环境变量（我只是在Cortana搜索中键入了它），然后单击环境变量。单击“路径”，然后单击“编辑”，然后单击“新建”，然后键入C：\ sqlite。
我在Windows 10计算机上运行了以下内容。
$ rails new blog
$ cd博客
$捆绑安装
$ rails服务器
然后返回以下内容：

问题是，然后我尝试删除C：\ sqlite文件夹，然后删除在“环境变量”中所做的编辑。然后在命令行中运行以下命令：
$ gem'sqlite3'，git：'https://github.com/sparklemotion/sqlite3-ruby'
然后返回：
错误：执行gem时...（Gem :: CommandLineError） 未知命令sqlite3，
所以现在我真的很困惑。

幸运的是您的系统是64位，因为我不知道32位的解决方案。
下载此内容：
https://ci.appveyor.com/project/MSP-Greg/sqlite3-ruby/build/3/job/hhk6ie8gdo545svr/artifacts
在下载它的文件夹中，打开cmd并运行：
gem install sqlite3-1.3.13.20180326210955-x64-mingw32.gem
在cmd中可以使用更短的方法，但是我很具体。

我删除了所有内容。红宝石，rails，sqlite。然后我下载了RailsInstaller并使用了它，就可以了。第一次尝试RailsInstaller时，它似乎发生了错误，做了一些奇怪的事情。这次没有。
