Ruby on rails 无法运行rails服务器无法找到sqlite3

我找不到关于堆栈溢出问题的答案，我想这可能是因为我在遵循youtube教程后以错误的方式安装了SQLite3

我按照本教程安装SQLite。我最初安装在SQLite网站的预编译二进制文件部分。我提取了文件，然后将其粘贴到C:\sqlite中。我将文件夹的名称更改为sqlite。然后我去编辑系统环境变量，我只是把它输入Cortana搜索，然后点击环境变量。我单击路径，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操作

$rails新博客

$cd博客

$bundle安装

$rails服务器

然后它返回以下内容：

问题是，然后我尝试删除C:\sqlite文件夹，然后删除我在环境变量中所做的编辑。然后，我在命令行中运行了以下命令：

$gem'sqlite3'，吉特：

然后它返回：

错误：执行gem时。。。Gem:：CommandLineError 未知命令sqlite3

所以现在我真的很困惑。

C:/Ruby25-x64/lib/ruby

幸运的是，您的系统是64位的，因为我不知道32位的解决方案

下载此文件：

在您下载的文件夹中打开cmd并运行：

gem安装sqlite3-1.3.13.20180322610955-x64-mingw32.gem

---

在cmd中有一些较短的方法，但我已经具体说明了。

我删除了所有内容。Ruby、rails、sqlite。然后我下载了RailsInstaller并使用它，它工作正常。我第一次尝试RailsInstaller时，它做了一些奇怪的事情，似乎出错了。这次没有。

我不想看YouTube视频来了解你做了什么，我怀疑其他人也不会，所以我建议在你的帖子中包含视频中的相关信息。但是我可以告诉您，命令是gem install sqlite3，而不是gem sqlite3。您应该能够打开控制台并从命令行运行sqlite3。我怀疑它不在您的环境路径中。
