Cannot find name ‘console’. Do you need to change your target library? Try changing the ‘lib’ compiler option to include ‘dom’.

背景：

在通过ts-node工具执行test.ts文件时，出现了如下报错信息

D:\WebstormProjects\web-demo-master\typescript>ts-node test.ts
 C:\Users\Administrator\AppData\Roaming\npm\node_modules\ts-node\src\index.ts:820
     return new TSError(diagnosticText, diagnosticCodes);
            ^
 TSError: ⨯ Unable to compile TypeScript:

 }

出现该报错信息，主要是因为没有配置tsconfig.json文件导致的

解决办法：

1、首先需要进入到test.ts文件的目录下，然后执行tsc -init命令，从而创建一个tsconfig.json的配置文件

2、然后再次通过ts-node执行test.ts文件即可
