# 前言 #

因为之前对前端设置这方面有一定的学习，认为这方面学起来非常有意思，但是因为自己可能是菜鸟，所以出现的错误也不少。在网上总是能看到很多前端大神提起Angular，但是我对这方面不太了解，所以就想学，丰富自己对前端的认识，因为之前没有接触过这方面的知识，所以出现错误的概率很大，接下来我就介绍一下我遇到的这个bug，希望对大家有帮助

# 内容 #

搭建好Angular环境，因为教程里面是用cmd搭建，然后给出了查看搭建结果的的代码：`ng serve`，所以我就尝试了一下，出现的内容是这样的，如下：  
![这里写图片描述][70]  
这说明环境已经搭建好了，而且已经成功执行了。这个时候我的WebStorm也安装好了，于是我点击进去，找到相关文件打开，点击运行，打不开网站，并出现下面错误。

![这里写图片描述][70 1]  
因为我是刚刚才开始学习Angular的，所以觉得懵逼了，因为刚下载，什么东西都没有敲，直接运行的话应该可以的啊！但问题就是我运行不了，而且报出了上面的错误，没办法，百度一下，给出的答案是：我已经启动了该项目，所以无法再次打开，原来这样。  
解决方法：  
将cmd命令窗口关闭，然后再在WS中运行，这次成功了。在WS中部署完代码，然后成功加载，显示的内容如下：

"D:\Program Files\JetBrains\WebStorm 2018.2\bin\runnerw.exe" "C:\Program Files\nodejs\node.exe" "C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js" run start --scripts-prepend-node-path=auto

此时，打开浏览器，输入`http://localhost:4200`，立马可以执行，别问我为什么输入这个代码可以执行，因为这时部署时候给出的网站，如下图：  
![这里写图片描述][70 2]  
给出的网站打开的内容如下：  
![这里写图片描述][70 3]  
![这里写图片描述][70 4]  
这样说明已经成功部署了WS中的代码，然后成功在指定的网站打开。

# 总结 #

刚开始学习Angular，然后遇到bug，心中莫名有一种恐惧感，也许这是它给我的下马威，没关系，我会慢慢积累自己的能力，然后逐渐的去熟悉它，认识他，了解它，然后跟它一块合作做出所期待的美好的项目！

谢谢您的阅读！
