所以，我跟着一个udemy angular课程，讲师是用mac而我用windows。当我创建一个新的项目，我从他得到不同的屏幕是正常的，或者我错过了什么。这些屏幕都是附件，我的是黑屏。我得到了一系列的创建命令，然后是一系列的警告。

你可以忽略这些警告。在我印象中，它们与git有关。当我几个月前参加他的Angular课程时，我使用Win 10 Pro没有任何问题。
你是否使用vs代码终端来安装clinpm？
这是他的课程内容1.5中关于解决安装问题的信息。
通过确保你使用最新版本的NodeJS、npm和CLI本身，很多问题都可以解决。
更新NodeJS。
到nodejs.org下载最新版本--先卸载机器上的（所有）安装版本。
更新npm。
运行[sudo]
npm install -g npm(sudo是Mac Linux上才需要的)更新CLI
[sudo]
npm uninstall -g angular-cli@angularclinpm缓存验证
[sudo]
npm install -g@angularcli以下是一些常见的问题& 解决方案。
创建一个新项目需要很长时间（超过3分钟），这在Windows上时常发生 => 尝试以管理员身份运行命令行。
你得到一个EADDR错误(地址已经在使用中) 你可能已经有另一个ng serve进程在运行--确保退出该进程或使用ng serve --port ANOTHERPORT在一个新的端口上服务你的项目。
我的更改没有反映在浏览器中（应用程序没有编译） 检查运行ng serve的窗口是否显示错误。如果不是这样，请确保您使用的是最新的CLI版本，并尝试重新启动您的CLI。
希望能帮到你
我想这是Windows的标准，使用两个字节作为回行。
这只是意味着创建的文件将被修改，以更好地适应你所使用的操作系统的标准。
没什么好担心的。
