我正在尝试遵循一些web开发主题的在线教程，这些主题在github上有相关的代码。当我下载它时，关联的目录结构如下所示:
E:devangular-components-step-1>dir

创建我正在跟随的教程的人说下载后运行npm install。当我这样做时，我得到了以下内容:

在我看来，问题是这个应用程序中使用的包的新版本自本教程创建以来已经出来了。
我的问题是:
即使这些包的新版本已经发布，为什么我不能直接使用project.json中指定的版本?
如果我想让这个工作，我需要遵循的一般过程是什么?也就是说，我是否可以得到当前版本，一切都应该工作，或者我需要做些什么来确保一切都能一起工作?
是否普遍认为这样的事情会发生在从github下载的项目中，如果他们是在一段时间前创建的，这只是经常需要处理的事情?
更新不会影响以前的版本，只影响较新的版本。所以，只要它在你所遵循的教程中有效，它也应该适用于你。但是，请注意，package.json中的插入符号和波浪符号操作符相应地下载最新的次要版本或补丁版本。因此，您可能会使用比教程稍微更新的版本。无论哪种方式，通常都不会引起问题。
